How to install Remix OS alongside Ubuntu (Dual Boot) - Remix OS for PC

1. Create a second ext4 partition for Remix OS using Gparted
You should delete the linux-swap and the extended partition first. After reducing the size of your Ubuntu partition sda1 you can create your Remix OS partition sda2.
Finally you'll create a new extended partition containing the linux-swap.

2. Install Remix OS into the new partition
Use the steps described in "Installing Remix OS to Hard Drive or Virtual Machine without additional tools", but there are a few differences:
- Skip step 3, because you have a formatted ext4 partition already (in my example: sda2)
- Step 4: Select sda2 for your installation (formatting of sda2 not needed)
- Step 5: Do not install a boot loader GRUB; do not install EFI GRUB2 (you'll customize the Ubuntu boot loader)
3. After a reboot Ubuntu will start. Please install grub-customizer
sudo apt-add-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
4. Start grub-customizer and add a new entry (Ctrl + N) named e.g. "Remix OS", Type "other"
Boot sequence:
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,2)'
linux /android-2016-07-12/kernel quiet root=/dev/ram0 androidboot.hardware=remix_x86_64 androidboot.selinux=permissive SRC=/android-2016-07-12
initrd /android-2016-07-12/initrd.img
(hd0,2) has to be changed if you use a partition other than sda2 on hd0 for Remix OS.
Example: If you are using sdb2 on hd1 the "set root" command is
set root='(hd1,12)'.
You can obtain the Android path (e.g. /android-2016-08-11/) by mounting the Remix OS partition with the Linus file manager.
Example of boot menu entry for Remix OS
http://postimage.org/index.php?lang=german
If you are working with the Remix OX 32bit version you have to use ". . . androidboot.hardware=remix_x86 . . ." in the last line (beginning with linux).
Example: With version 3.0.103 (2016080805) 32bit the line has to be:
linux /android-2016-08-08/kernel quiet root=/dev/ram0 androidboot.hardware=remix_x86 androidboot.selinux=permissive SRC=/android-2016-08-08
initrd /android-2016-08-08/initrd.img
5. Make the Remix OS entry the second boot menu entry
http://postimage.org/index.php?lang=german
6. Modify the General Settings
- Default: first entry
- Show menu
- Start default after 5 seconds
http://postimage.org/index.php?lang=german
7. Save the new grub configuration
8. Check the new swap UUID and correct it in /etc/fstab
sudo blkid | grep swap
9. Reboot and select the second entry "Remix OS"

Thanks for the guide it's really useful for me since I'm already using ubuntu and had a separate partition ready for another OS.
I am having some trouble with the grub configuration.
Error: Disk <<hd0,3>> not found
alloc magic is broken at 0x6ff89b20: 6fded940

Here's my disk layout:
sda1 EFI system partition

And here's my grub entry:
insmod gzio

initrd /android-2016-07-12/initrd.img

I have changed only "insmod part_msdos" to "insmod part_gpt" since I'm using GPT/UEFI (I'm running it on an old mac mini, only boots UEFI)
Any idea what might be wrong? I already triple-checked the grub entry and stilll can't figure out what's going on. Tried also editing hd0,# on boot to no avail either.
EDIT: Would it be easier to have it as single OS? I already backed up and cleaned the HDD.

Are you sure it's (hd0,3)?? You may have to recheck that. Enter the command mode by pressing 'c' at Grub menu and execute 'ls' command to list partitions. I guess it must be (hd0,gpt3) or something like that. You can double check which is RemixOs partition by using 'cd' into each partition executing 'ls' to list files.

Thanks Thisu, but no dice, I even tried installing RemixOS as the main OS without any luck. I have used crappy linux installers (like way back knoppix) but damn Remix takes 1st prize. Right now I'm trying to reinstall GRUB2efi from an ubuntu live USB. No matter what kind of installation I do for Remix I get the typical "blank" GRUB screen (the one that states "....minimal bash command...." and a GRUB> prompt)
I don't know what's the matter with this installer, it's never consistent. sometimes it asks for a data file creation, sometimes doesn't, sometimes just reboots after the install, sometimes prompts what to do... Resident mode tends to work but from this particular drive and computer, is barely useable due to poor speeds. And trying to repurpose an old mac with this is far worse, the PoS won't even try booting a normal MBR scheme. it HAS to be EFI
/rant

I am no GRUB specialist, and I do not use EFI. I found a working GRUB configuration for Remix OS by copying and modifying the primary GRUB configuration for Linux Mint 17.3. The tool I used is the "grub-customizer". I installed Remix OS in partition sda2, and "set root='(hd0,2)' " worked for me.
I created and formatted sda2 using GParted; so during the Remix OS installation sda2 did not have to be formatted. Because I wanted to use the Ubuntu GRUB installation, the Remix OS installer has been told not to install GRUB und EFI GRUB2.

In case if someone still looking for help, use the example below. I was successfully able to boot with configuration below.
All you have to do is to mention right gpt partition where you have installed remix os mine was gpt6.
Then by running the "blkid" command in ubuntu terminal find the UUID of the partition
Replace my UUID which is in this example with yours.
Instead of root=/dev/ram0 use root=UUID of the partition.
Hope it will help some
insmod part_gpt
insmod ext2
set root='hd1,gpt6'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd1,gpt6 --hint-efi=hd1,gpt6 --hint-baremetal=ahci1,gpt6 c604b8c5-95f4-4b14-b0cb-88bd45d871e9
else
search --no-floppy --fs-uuid --set=root c604b8c5-95f4-4b14-b0cb-88bd45d871e9

Installing Ubuntu first is at least easier, because Ubuntu will not detect Remix OS as "installed system" and will not offer installing Ubuntu as second system, providing dual boot.

ok, i have finally install everything,followed what have been put here.
but i get an error once i choose remix os on GRUB
error '/android-2016-07-12/kernel' not found
error 'you need to loadthe kernel first'

@remixtester
Firstly, thanks for the guide. I've got it mostly figured out but I have a couple of questions for you.
The partition I have installed Remix to is sdb12, so how would I edit the grub? Is it:
Code:
set root='(hd0,12)'
or
Code:
set root='(hd1,12)'
or something completely different?
Answer:
sdb = hd1 so the code is:
Code:
set root='(hd1,12)'
Also, the "/android-2016-07-12 has to be changed if you will use a Remix OS version other than 2.0.403 (2016-07-12)" section might need a little more clarification. I understand that I need to change this because I'm using Version 3.0.104, but there's no indication in this guide on how to find the correct information for builds that differ from the one you mention using. So how do I find out what to change that line to (as per the build I downloaded)?
Answer:
Mount the partition you installed Remix to in the Linux file manager and view the folder there.
Even though I've answered my questions I'm leaving this here for anyone else having the same questions in future. It might be a good idea to add this info to your guide.

Which version of Remix OS did you use? 32bit or 64bit?
What's the name of the partition where you installed Remix OS?
Did Remix OS start after you clicked OK here:
http://postimage.org/index.php?lang=german
Which boot sequence did you enter into the boot menu entry for Remix OS (Ubuntu "Grub Customizer")?

Actually i did a mistake. Infact its a mistake in your code for boot sequence in your guide
In eg of 32 bit , you have written initrd=/andoid..... And correct is initrd /android......
Anyways hardly matters, your guide was awesome. Thank you !!!

helpp
I followed every step on the guide, but when I try to boot Remix Os, it just says "disk /dev/ram0 doesn't exist", I don't know what to do, I've tried changing /dev/ram0 for other disks and dir,, but just says the same "disk -the disk I decide to put- doesn't exist
also, sorry for my bad english, I mostly speak spanish

Ok everything went ok boots up and runs fine. my question be if you were going to root this you would want it to be after you make the bootable usb which will then change it to system.img and make the change on the grub customizer then install it to the partition with "Tab" INSTALL=1.

error when trying to start Remix OS
After the procedure, when I tried to start the operational system an error appeared "error archive '/android-2016-07-12/kernel' not found. alloc magic is broken at 0xb798ee00: b76cfc20." . How can I find the correct name of the kernel I had installed to make some changes in the grub costumization.
Thanks.

Label RemixOS partition as RemixOS using gparted and use the script in below link either through custom grub entry or grub-customizer.
