thanks digimax, i have read that several times over and have tried everything i can think of. i have used different sd cards, different usb cables, usb ports on my machine. i even went out and bought a brand new 8 and 16GB class4 sds and still nothing. i have used win 32 disk imager, acronis dd, ubuntu live, and fedora core that i have dual boot on my machine. i have downloaded the image from 4 different sources( using alberts method) and tried each of them numerous times. is it possible that my NT is unrootable? would it help if i downgraded from 1.4.3? if anyone has a verified working link on an image ill try that. if i can get CWM going then i can take it from there as far as kernels and roms, its just getting to that point that is so frustrating

Just to confirm: what you burn to the SD card (using win32diskimager) is the .img file extracted from inside the downloaded zip file, and not the zip file itself?

I extracted the zip which contained win32diskwhatever and the image file i used win32 in admin mode to write the image and create the partition on the sd card. im currently abandoning that route though and am just going to try breaking down and flashing CM10.1 on it. i saw a post where you had stated that that was an old way so im going to try something newer. i have all the files downloaded and have built the partitions using mini tool partition manager im copying them over now but i think it will be tomorrow before i try to flash ill let you know if it works, and just to be clear when i flash the CM10 on the sd card i can remove it and the NT will still boot CM10?

If you flash onto and run CM off an SD card (e.g., as described in http://forum.xda-developers.com/showpost.php?p=36685310&postcount=1), that CM10 SD card has to stay in the SD card slot in order for your NT to run CM10.
If you want to be able to run CM10 without an SD card you'd have to flash CM10 internally on EMMC (e.g., see http://forum.xda-developers.com/showpost.php?p=43326042&postcount=123) to replace whatever ROM (stock or otherwise) you currently have.
Note thatSD-based installation and EMMC-based installation use different versions of ROM zip files which are not interchangeable, so make sure you pick the right version.

ok i tried using the premade image and putting it on the sd card to boot from. i made sure card was flagged as primary active 0x0C LBA and it was set to boot( if that makes any sense, been up too long lol ) that didnt work. so i tried to build the card my self reading through several times and double checking as i went. still nothing when i try to boot up with the usb cable. i have been using the stock cable could that be a problem? this is what i came up with when the NT booted normal (attachment below) can you tell did i do something wrong? would it be easier to throw CM onto the eMMC? if so can you link me to a version of CM that would work on the NT 8GB? thanks in advance!
Personally, I had trouble booting & running SD cards. I'm convinced it wasn't hardware but my noobness! Since then I've always loaded only to emmc. I also had trouble going directly & straight to CM10 roms from the B&N 1.4whatever OS.
So, looking for a recovery + rom that matched, I used Indirect's app to get cwm 5, then had no trouble loading a CM9 rom (all to emmc). Once CM9 was up & running good, I used Goo Manager to load an updated TWRP recovery suitable for CM10, then Cm10.1, etc. That's what worked for me & to this day I see no need to boot from SD's. Just me tho.

If booting of a pre-made image does not work, there might be a flaw with your NT that precludes it from booting off SD card, and if this is true I am not aware of any way to root or flash stock ROM onto emmc if your NT is currently running stock.

It's indeed true that there really doesn't seem to be anyone not being able to get their NT to boot from sd, provided they follow suggestions. So I repeat the questions I asked in your own topic (and please, try to stay within one thread to maximize the chance of getting this sorted!):
1. Are you 100% you are dealing with a Tablet and not a Color? (Model no fr Tablet 8GB is 250A)
2. Are you using a SanDisk class 4 sd card? (And burn it according to instructions)
3. Have you tried turning the device off, inserting the card and then insert USB cable connected to power (not computer!)

ok through a series of unfortunate events and through no fault of my own i now no longer have a NT but i do have a nook color now. for those of you wondering i DID have a tab but the screen ended up mysteriously shattering. wife was trying to be nice and ordered me what she believed to be a tablet but a color shipped instead. still trying to decide if i want to do anything with that but thats for a different thread. so i still dont know what happened the tab wouldnt boot CM10 before it broke ( or after either lol ) but i pulled the sd out and tried it again in my wifes tab using the wall charger to jumpstart it and it booted CM right up. so i guess i just got the crap draw out of the nooks we bought at the exact same time. still trying to figure out how i can pin this on best buy for selling me a faulty device lol, but i just wanted to say thanks for everyones help and feedback. when i threw the sd into my wifes tab it loaded CWM and CM10 just fine. ordered her a class 6 san disk sd to put in it to see if that helps with some of the lag issues.:good:
Ok, so I'd like to piggyback off this before starting my own thread. I have a bunch of Nook Colors that I have no problem booting off of SD cards for my kids. Now the 8gb Tablet is proving much harder for me. I've redone the SD card method 4x by two different methods and I keep getting the same result: It boots up fine, allows me to create the google account and even dowload apps. However, out of nowhere it will reboot and then I am stuck on the CM10 boot screen that just loops forever. I am repartioning a 16 GB card, making it active, windisk img the zip file to the card fine.... Does my symptom sound specific of something? Let me know. Thanks!

I encountered this same problem for the first time yesterday when I tried out a CM10.2 SD build.
If you are using 10.2 you might want to go back to using 10.1 for a while longer.
Yeah, but what if I'm on CM 10.1? I used one build from June (2x) then one from Aug (2x) and now have the same symptoms. This does not sound indicative of something specific? Like aren't some 8gb tablets troublesome from SD? Or is this a user error still of some sort?

I have an 8GB Nook Tablet and made the foolish mistake of attempting to try and root it with acclaim-update.zip. Now my Nook will no longer boot and I've tried every unbricking method available. No progress was made.
I was a bit too eager to eager and rushed headfirst into it without researching it more thoroughly. If there's no fix for it, then that's fine. I just wanted to run through ever resource possible before giving up on it. I have spent the past few hours scouring the internet and coming up with little to nothing.
Have you tried booting CM7 from sdcard?
What things have you tried to make it boot?

Shouldn't you just be able to put the unmodified acclaim_update.zip on your sdcard? It should work and fix your nook. When you put the sdcard in, make sure the device is off, and then connect it to the power adapter to get it to turn on
IF its completly dead/ erased boot erea then your only option will be jtag.

So far I've tried the Ubuntu method of unbricking it, factory reset, and booting with the 1.4.2 zip file to return it to factory settings. None of them have worked.
But I'll try CM7 and see if it works.
Am in the the same shoes... got a bricked NT 8GB... looking forward to restoring 1.4.2...
attempts to restore the firmware to factory:
Cyanoboot + altboot + B&N 1.4.2
Followed guide here http://forum.xda-developers.com/showthread.php?t=1562130 , using (a) the img from dropbox and (b) nooktablet_1_4_2_update.zip from B&N. No luck. The process stops on the initial screen on cyanoboot, where it shows 'Loading (sd)...'. I don't even get to enter the menu that shows the boot options.
flashing_boot + B&N 1.4.2 update in ext3 partition
Next I downloaded the img link above, http://forum.xda-developers.com/showpost.php?p=24912163&postcount=5 , no luck also, the tick appeared on the flash 'Installing new software' screen after 4 minutes. After I removed the mSD card, the NT did a data cleanse, and got an error message about 40% into the factory restore prompting me to contact B&N. It then goes into the reboot loop (this is where I am now).
Ubuntu unbrick
No luck. NT don't even boot up to mSD with the mSD card slotted in.
I've tried the above multiple times, downloading the files few times as well. Am still stuck in the reboot loop.
Would like to seek help from gurus here for pointers... Am stuck at this point.
Thanks alot!

Can you get to CWM using Indirect's NT-CWM-SD package from here: http://forum.xda-developers.com/showthread.php?t=1466583
Get a micro SD card, fire up gParted (or whatever partition manager), put a new MSDOS partition table on it. Then make a new FAT32 partition at the beginning of the disk. Set the boot and lba flags. Copy the contents of Indirect's zip onto the disk. Stick it in the NT. Hold power + n for 10 seconds and wait for the grey "n" to show up on the screen for a second. Then turn it on.
If that takes you to CWM, then you've got options.
using a properly formatted SD card should solve most issues.. its the great thing about the nook.
1.make sure your using a good SD card. sandisk 8gb class and up would be best
2. make sure you grab the 8gb nook cm7 image.
3. preferably use a component based card reader. by that i mean one other then a laptops.. the laptop ones tend to be picky and lots of people in the nook color days had issues and most were resolved by using a computer one over a laptop one
4. with the nook OFF plug the usb cable into the nook then into the usb port on a computer
check out stickies too

Negative. I wish you were correct but - in this case - you are not.
Your advice is probably appropriate for those who cannot get an SDCard to boot properly. However, the O.P. has a bricked device and his original post is most descriptive. His NT8 will not boot to the INTERNAL EMMC. (I have the same problem.)
There are several of us here on XDA who are not novices with this issue. The O.P. has listed the various steps that he has followed and they are much more involved than a simple SDCard format issue.
BTW, most formatting issues are when users are attempting to format with Windows. I use Linux exclusively and I can ALWAYS build a boot SDCard without issues.
Also in the same boot as the O.P.
I also am having this problem. Been going through it for mths now. I've tried every possible fix people could come up with. I have been talking to a youtuber albertwertz. he would like me to send in my nook tablet to him to fix and try out different things. I would like to but cant afford it at the moment. Dang I hope someone finds a fix for this or make a cm9 sd bootale img or something dont get me wrong i like booting cm7 from sd but is this all im subject too. HELP SOMEONE. what are these developers working on. lets get this fix my people. PS thanks for all you all hard work on all roms.
Lost Nook 1.4.0 partition
Hi, Lavero.
I think I may have accidentally deleted the default nook partition. I can still boot up via SDCard and goes into CM7. How can I recover those default partition? Do you have those commands within Terminal Emulator or any other options?
If I do not put in my SDCard, with power cable connected, the nook tablet 16GB keep rebooting. I still want to recover my Nook default OS so that I can repartition it the next time I go to BN.
Hope to hear from you. Thanks.
I apologize if there is an answer to this somewhere but I have spent the last 3 days looking and could not find a clear answer. I have tried many different methods, SD cards and many many MANY attempts but I can not get my nook tablet to boot from the SD card. The closest I get is after I hold power and N to power up then down, insert the SD card and then power up (USB and Button get the same result). After the N screen I get a flash of the root screen but then the factory reset question. ANY help would be appreciated. My wife is going to kill me if I spend too much time on this! Thanks in advance!
What type and class of micro SD card are you using? I always have used emmc to boot, but it seems that a Sandisk Class 4 seems to be the recommended choice when attempting to boot from it. I also remember a issue along time ago when people would have to have their nook plugged into their wall charger to boot. Btw what ROM are you attempting to boot to? Also, whose guide are you following? Good Luck....

If you are trying to make a CM SD card, you can find instructions/tools here.
It is tough for me to follow those instructions. Sorry guess I am just a noob I was able to make the SD card but the instructions on what to put where on the card confused me. Can you help me out?

I will start this reply off stating that I am rather noobish.
I've seen evidence that the boot sequence has been modified by B&N to kill this procedure. I am in the process of doing the same with my Nook Color BNTV250a. I think we may have to over-write the emmc rather than use the microSD if possible. I really don't know why they care so much. We buy their product, and we want to make it more dynamic...

I posted an overview of the process I used to build a CM10 v0.06 SD card using Succulent's tools here.
However, you can simply just download a CM10 SDcard ready-made image built by Succulent and posted here, and write it to your SDcard.

Booting with sd on 1.4.3
I am having the same problem. I have tried a few different ways with no results. Anyone have any sucess yet?
this works for me
I'm new and I just installed CM10 on my tablet this weekend.
I had the same SD card issue.
Short answer for me is -- make the partition size of the SD card small in additional to the boot and lba flags settings and it worked.
I use 100-150 MB. Tried 300 MB and it failed.
I used an old 2G (class 1?) SD and a 16GB class 2 Sandisk, both behaved the same.
Nook Tablet had 1.4.3 installed and is about 9 months old.
To get my 1.4.3 Tablet to boot from sd I hold down the "n" when powering on. I let go of it before things really start going on on the screen. (5 seconds? I haven't timed it)
I have done all sorts of things from sd (rooting, repartioning, unrooting...). Some went well , some didn't at first, but thankfully there are guides here to get you back to where you started...
I am right now running CM10 from an sd card and it's performing amazingly well. You could always try that for a while! An almost fool proof guide here http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/ You don't have to mess with setting up partitions or anything. It's all done for you! Download, burn (and if you want to, espand one of teh partitions to fill up the card), pop it in and go!

If your NT is like mine, it will:
only boot from SD from a power-off state and upon insertion of a powered-USB cable
always boot into stock ROM if it's powered up via the power button
always reboot into stock ROM (even when tethered with a powered-USB cable)
If it does not boot from SD from a power-off state and upon insertion of a powered-USB cable, e.g.,
it gets stuck on a black screen then eventually boots into stock ROM, or
it boots straight into stock ROM without "hesitation"
then there is something wrong with the content and/or format of SDcard 1st partition, in which case check to make sure that 1st (FAT32) partition has LBA flag set and is set to active, and that the MLO and u-boot.bin are not corrupted (at least have the correct size in bytes) in the file copying to SD. I also found it helps to first copy the MLO and u-boot files then the rest of the files, since MLO and u-boot are to be loaded first, and it appears that OMAP only scans the first few entries of the partition-table to look for these two files.

I thought this was going to be rather straight forward, but I'm starting to curse technology. I tried making the bootable microSD card on a new 32gig class 4 Sandisk to no avail. I formatted it after to start from scratch, and now it cannot be detected. I haven't done anything really like this before, so I'm wondering if I should even bother risking the 8 gig card I use for music. I have the Nook Color BNTV250A as well.
hope this helps you out...

What process did you use to make the bootable SDcard?
Can your PC/Laptop detect the card?
Have you tried using a disk partition tool like "MiniTool Partition Wizard Home Edition" to see what's on the card?
I've seen multiple references to Nook Color and BNTV250A in the same sentence, but I believe that model number belongs exclusively to the Nook Tablet. I have an 8GB Nook Tablet with 1.4.3(pre-installed). I went through a lot of hassle with the SD card as well and what worked for me was getting the smallest size SD card I could find. I used a 2GB class 4 card. That worked well for me. On the boot process(from a powered down state with the SD card inserted) I started out by pressing and holding the "n" button and then pressing and holding the power button. I didn't release either until I saw the brown box on the screen so you might be releasing one of the buttons too early. Additionally I did not have a USB cable attached to my Nook during the whole process and it didn't affect the install in anyway. What I've seen with the USB cable attached is that a delayed power-on process is initiated once the cable is inserted. Maybe this defeats the "button press" sequence.
Good luck!

I apologize if there is an answer to this somewhere but I have spent the last 3 days looking and could not find a clear answer. I have tried many different methods, SD cards and many many MANY attempts but I can not get my nook tablet to boot from the SD card. The closest I get is after I hold power and N to power up then down, insert the SD card and then power up (USB and Button get the same result). After the N screen I get a flash of the root screen but then the factory reset question. ANY help would be appreciated. My wife is going to kill me if I spend too much time on this! Thanks in advance!

Hey guys.
I am somewhat a noob. I bought a brand new 8gb nook color from wallmart on black friday. I heard about how you can put CM onto the sd card and boot from that without altering the device itself. I have tried for HOURS to do this. I have looked up COUNTLESS walk throughs and done everything they say, done alternations, and used different cards ranging from 2gb sandisk (class 1?) to 32 gb sandisk this is a class 4. I've used winimage and burned the image to the card, then dragged over cyanogenmod and done this task in countless different ways. Every time I shut down the nook, put in the card, then re-boot, the nook does NOT boot from the card. It boots normal, then I can actually browse the card after it boots up. I have done it EXACTLY how it says here and read tutorials so its not a question of whether or not I have followed standard proceedure. My firmware version is 1.4.3. Ive searched online to this and to no avail. My sister bought the exact same one at the exact same time and it does not boot the sd either. I have done about 8 straight hours of research on this guys, so I'm no pro but I have a basic understanding of how it works now. My questions are this:
1: Did Barns and Noble put restrictions on the newest nook color or on the newest software version? And if so is there a way around this?
and
2: If NOT, is there an alternate way/installation onto the card that I can do (such as an image pre loaded with CM etc.) that I might be able to try instead of the conventional way?
Thanks guys! Sorry for the uber long post : S
i have read several threads. Installe Ubuntu on a laptop and have come to the conclusion.........I have no business rooting, or anything i hav tried several metods to try and restore my 16gb nt and have been unsuccesful. is there any body out there willing to try and restore it for me. i will pay all shipping and will send it with my 8gb class 10 card. I just want it restored to cm7 or something functional HELL even stock would be great at this point. I do not have the skills to do it myself. It has been bricked for over a month now. This was a device used by all of my family members and now they are all upset with me for ruining it. Will B&N take it back and do a restore? anything ANYTHING PLEASE HELP!
Can't you just start by telling us what you have tried?
Have you for example tried the repart.img card already? If so, what happened?
Edit: I checked you previous posts and see that you tried to get Adam's method going.
Before going through the trouble of sending the Tablet around, try the repart.img
http://raywaldo.com/2012/06/how-to-un-brick-a-nook-tablet-8gb-or-16gb/
In short
1. Download, extract zip and save the repart.img in the same folder as you keep your Winimage
2. Open Winimage from within that folder. (Do not "install" and run, just open from the folder!)
3. Choose the "repart.img"
4. Burn it to the card
5. Boot to the card (inserted in Tablet)and wait for green checkmark
6. Turn off, remove card and Tablet will reboot automatically.
If green checkmark doesn't appear after a few minutes and a red cross appears instead, then you're in trouble and nee to try soimething else. But let's hope it deosn't come to that!
o.k.
Thank You! i have followed these instructions. i even started out with a new 8GB SanDisk microSD and a new usb card reader. i was able to successfully create the card. My 16GB NT does boot to the restore screen but I do have the red x in the corner the whole time. When it finishes, i get a the device will shut down in 5 sec. I have tried the re-boot without the card as well as booting with the power button and the cable. i am waiting for a fresh download of adam's file to try that agin. If that does not work I will move onto celtic's instructions.
FINALLY!
Alright! I have returned to stock. courtesy of the AdamOutlerUbuntuTotalReFlash. The problem is the touch screen doesn't work. I will be attempting to restore to a previous cm back up from here. I owe more than thanks to so many people here. asawi, AdamOutler, Albert Wertz, Celtic, indirect. and all who helped. them. I have learned a bit in a minute and have a long way to go. My 16 GB NT isn't fully restored but, it's closer today than 4 -5 weeks ago!
Woohoo!! And I see you already know how to fix the touch. I'm sure you'll do fine, and I hope you come back and let us know about your success!!
not quite
i am pretty happy with my success so far. and it is all due to this forum. I haven't figured out how to fix the touch yet. I have tried to flash a few different things but no success yet.
Have you tried just running CM10 from sd card? I don't know if you can do that and restore original touch firmware, but it's worth a try!
The Touchscreen app is included, so it "should" work...
Here's a link to and easy-peasy versio:
http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/
Download (first download under "Download", ending with SDC-IMG.RAR), extract and put img-file in your Winimage folder, burn to card, pop into Tablet and boot into sd card.
Open the Touch firmware app and go back to original.
Remove card and rebbot into stock and hopefully all is well now!
Since you don't actually plan to run the Tablet that way you don't have to expand the user partition on the card, just run it as it is!
Edit: FWIW, I went and tried to flash touch formware while running CM10 from sd-card, and it seems to work fine. I then took the card out a and rebooted to my "regular" (internal) CM10 and reflashed the touch firmware back to what it was.
(I have no need for 10 touch right now, so I keep it in original until I do),
So you really should be good to go with Succulent's (Iamafanof) ready-made CM10 (or CM10.1) card images!

I think what I am going to try is re-create and boot from the the AdamOutlerCard and see if that clears up the problem. The nook doesn't seem to recognize the sd card or the format? and will not boot to or from the sd card (CWM) . and then I will move on to Succulent's http://iamafanof.wordpress.com/2012/...r-nook-tablet/ . I really appreciate the advice and all the help.

At what stage of the recovery did you get this error message, e.g., during the process of initial sign-in to B&N?
o.k. I have achieved boot to SD card using sucullent's iamafanof cm10 image as instructed by asawi. my next goal will be researching and flashing the internals again. i suspect my initial problem resulted from having both cwm and cyanoboot resulting in the two arguing for permissions and rights. Additionally flashing the 10 touch which led to an unresponsive screen, which led me too trying to clear the "wrong" boot or mount and leaving me with only the cwm boot. patience!, clear thinking and help from all of you here got this device back in working order. Again I am extremely grateful for all the help!

Yes! Touch is working. I have not completed the registration for B&N yet. It seems that the updates that they push make it more challenging to root and / or flash to internal. I am just running CM off of an 8GB Class 10 micro SD. I don't want to do the B&N registration yet because I haven't 100% decided to flash to internal. Can the updates still be pushed even thogh I haven't registered? I am considering to keep running of an SD and get a 32GB class 6 card to do that. I would like to have the internal flashed because well let's face it the NT really isn't much to talk about until you. Unlock it's true potential. Question this process which I have followed here the repart and return to stock but running CM off the SD is that considered root?
I'm currently running CM 10.1 from an SD card and it does the same thing as internal boot. All information stored on the SD card with root privileges.
Sv: [Q] PLEASE HELP I GIVE UP and throw myself at the mercy of this community
I can't see any reason not to register your device if possible. You can block updates even if you're running stock as long as you're rooted.
It's more convenient running from internal than from SD, but I can't say I noticed much improvement in performance. Stick to class 4 unless you already have the class 6 lying around.
Be prepared that there might be problems registering after running the Ubuntu restore due to serial number possibly having been wiped.
O.K.

Alrighty then. I guess I will stick with just running off the SD card then. If I can't register then I will probably flash to internal. just curious why stick with class 4? Does the class 4 just run better or more compatible with the NT? How can I can confirm root?
SanDisk class 4 is the SD card most often recomended för NT. Runs fast and well and even devices that are fussy boot easily from it. The way data needs to be read for this kind of use isn't any faster on a higher class.

Is it possible or realistic that I can run a different SD card for different people using the tablet? i.e. using an 8 gig card with games and such for my kids to use. another card for my wife and then a card for myself. My fear is that the kids will eject the card or just not really know what they're doing and do something accidentally? (They are kids after all). My wife doesn't like the fact that I keep changing the configurations. Just overall giving everybody the ability to have the apps and configuration they want without encroaching on somebody else's preferences and hogging up all the space available on the card.

Yes that is possible. Just write the SDC version from iamafanof's page onto separate SD card. Recommended to use at least an 8GB Speed 4 microSD.
The other option is to use the profiles/users feature. It might be only CM10.1 builds that have the User capability. You can set up different accounts for yourself, your kids and your wife.
Okay. So my first issue is that I have been ebaying nook colors. Apparently I ended up getting a 16gb nook tablet instead of a color this last time. So the rooting process is apparently way more pain staking than the color was. Here's what i've tried so far.
First i tried this method:
http://forum.xda-developers.com/showthread.php?t=2056626
I set up one main partition, set it as active, my computer found it, and I moved all the appropriate files over. Inserted the SD card into the NT, plugged in the power cord and BLAM..... it won't even turn on. Pop out the sdcard, and it powers up just fine. So that got me to thinking. maybe i did something wrong, even though i followed the directions to a t.
So I decided to try the other method:
http://iamafanof.wordpress.com/2012/11/11/how-to-guide-bootable-cm7cm9cm10-sdcard-for-nook-tablet/
well. CM10 is 60mb to big for the way that that guy wants the partition setup. So i figure.... okay. I'll just swap CM10 for Liquidsmart (http://forum.xda-developers.com/showthread.php?t=2274244) and it's still to big! So I Deleted Gapps and now LiquidSmart fits.
So i'm about to try that method. i'm hoping it works. But i'm concerned because it doesn't call for a boot menu (re: twrp) to be transferred to the sdcard. So here goes. I'll post back in a few.
eta: WHOOT! Progress! got the boot screen to come up. but now it says "booti: bad boot image magic (in memory)
thoughts?
Get readymade.image here and run CM10 from sd. If you decide you want to install internally you can use the card to boot into CWM and install internally from there. It runs extremely well from sd though!

Sent from my GT-P7300 using Tapatalk 2
okay. so here's where i'm at. to be able to actually get INTO the boot menu you have to modify the files per http://iamafanof.wordpress.com/2012/11/11/how-to-guide-bootable-cm7cm9cm10-sdcard-for-nook-tablet/
the problem with this is that none of the roms i've tried will install after modification. They will attempt to, but they all abort due to one reason or another. that is to say that they will not install.
"set_perm: some changes failed
E:Error in /sdcard/cm-10.1-20130605-UNOFFICIAL-acclaim.zip
(status 7)
Installation aborted."
Why not use the readymade image I suggested? Just download, burn, expand one partition if you want to and run. Easy peasy!

It looked like you were trying to follow a guide to make a sd card install so I gave advice for an Easter option.You can still use that readymade image if you want to as a bootable CWM card and then install your ROM and corresponding gAppps.

Go and get a 16 gig microsd card and try it again.
A 2gig card is only good for recovery.
Are you trying to make this a dual boot thing with CM10.1 and the B&N original? or are you getting rid of the original os, and going stricktly Android?

it's been about a week since i tried this last so i forget exactly where i'm at. One of the tutorials i used got me into the boot menu but nothing would flash over. All the tuturoials saying to use winimage don't work at all. and thanks to that program I lost 10 years worth of programs because i chose to ignore what drive I was formating. Luckily i was able to use a partition checker to get most of them back. but that's another story.

Dude, I have a Nook Tablet 16GB too. It's really easy to flash, takes literally 10 minutes max.
Don't randomly do things next time, I took many hours to research before flashing my NT with Cyanogenmod.
Watch this video. This guy explains things really well.
youtube (dot) com/watch?v=c6D4s3okNQk
Not sure what your problem is. I took my Nook Tablet 16GB from a rooted stock 1.4.3 ROM to CM10.1.2 stable release in about 15 minutes. Fully set up, apps installed, multi-touch FW installed in less than 30 minutes. One of the easiest upgrades I've ever done on an Android device. And this 10.1.2 is amazingly stable, fast, excellent battery life, like having a brand new tablet.
I reload CWM recovery to get out of a boot loop. It has worked every time so far. For me, every time I've tried to load TWRP I get into a boot loop.
Ok, first off I want to give a big thanks to digixmax for all his help so far! His quick responses have helped me to stay somewhat calm even though I am extremely frustrated right now. I have tried several different ways to root and boot CWM and CM 10.X onto my NT the last few days and nothing seems to be working. I have tried http://forum.xda-developers.com/showthread.php?t=1439630, http://forum.xda-developers.com/showthread.php?t=2098419, http://iamafanof.wordpress.com/2013/01/09/cm10-1-android-4-2-1-jellybean-sdcard-img-for-nook-tablet-0110/, and http://forum.xda-developers.com/showthread.php?t=1529553 all with no success. i have used different cards, usb cables, and ports. i have used mini tool partition manager, acronis, gparted on ubuntu live, and fedora core that i have dual loaded on my laptop. i have downloaded the same files from different sources making sure to keep them separated in case one image is corrupt. and i have tried the preloaded image and built my own files onto a partitioned card making sure the card was set to FAT32 primary active 0x0C LBA and that boot was flagged. if anyone else has a suggestion i am all ears. im not opposed to just rooting into the eMMC either if someone wants to point me in the direction of a link with CM7.X or newer. the last build that i did on my sdcard looked like this (attachment below )
im not sure if anyone will be able to tell me if i did something wrong, maybe by file size? if more info is needed let me know. thanks in advance!
It's unclear to me what you want to do. Do you want to run CM10.x from sd card or install it internally? Or juts root? "Root" does not mea installing an alternative ROM, so it would be good to know what you're after.
If you want to run from sd Iamafanof's images should work. Personally I prefer his Android 4.1. Try it:
http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/ (It was not among those you said you've tried)
If it's not working, come back with more info on what you actually do and what happens (or doesn't happen).
If trying to install internally that image from Iamafanof can be used as a bootable CWM sd card and you can install CM10.x from there.

i was trying to root and rom CMsomething. at this point i dont care how it happens so long as something happens. your right i havent tried booting CM 10 and was actually looking for the version you posted. i read it was a good ver of CM to run on the NT. something that just started happening this morning when i use win32diskimager as admin a box pops up saying File error an error occured while accessing the device. This usually means that something else is accessing the device, please close all applications and try again. Error 1. Incorrect function. not sure what this is about. anyways ill try CM10 from that link and let post back later. thanks!
Make sure any file explorer is closed. That's what usually prompts that error for me. (I insert my card adapter, and the file explorer tries to access it.)

ok that helped some. its now saying write successful again. i tried the first link you gave me for iamafanof and that didnt work either, it still booted straight to stock. i guess im going to try flashing it to the internal memory. i cant believe how much trouble this is giving me, ive never had near this much trouble rooting and flashing with any phone ive ever touched. with the phones i may have been down a day or two trying to find a solution but today is going on day 4 or 5 that i have been trying to do this. time to try an alt route i guess. quick q, if i were to try and downgrade firmware from 1.4.3 do you think that that would help? has anyone tried this?
Having it installed internally is so much more convenient!
But before you give up on booting from sd, have you tried turning the NT off, inserting the sd card, and then plug it in to the charger? That usually gets even troublesome devices to boot from sd.
Edit: Version of stock firmaware makes no difference at all.

ok thanks i was hoping it would make some kind of difference. i have tried booting the NT with the power button, with it off insert sd and then jump start it with my stock cable and other usb cables. i have tried different usb ports on my computer with the cables and still nothing. i have been reading for days and trying everything. ive looked on xda, tabletroms, as well as many other sites that have dev support for the NT and rooting. thats why its so frustrating. im done i think with trying to boot off of the sd card. just going to have to start researching doing it by internal memory. i dont really care either way if i keep the stock software i think i would just be happy with even an early version of froyo or eclair at this point lol. if anyone cares to post links on rooting and installing roms on the eMMC or has any other suggestions about booting from the sd im open for suggestions. thanks guys for your help so far.
You say you've tried different ports on the computer but I told you to connect it to the charger. And also, just to make sure, you do use a class 4 card? SanDisk seems to be the preferred brand.
And I've already posted a link to my instructions.
If you can't boot from SD card any modification will be difficult so you need to get that part sorted.
Edit: And I also take it you are absolutely sure you have a Tablet and not a Color? Model 250A. I ask because it's not uncommon people mix them up.
