[GUIDE]Triple Booting Remix OS, Linux and Chrome OS

The trick is to install Chrome OS first, shrink the Chrome OS main partition, and install Linux and Remix in their own partitions.

• Download Chrome OS from here and install it as directed. It will destroy everything else on the disk, and make a large partition for data storage, and another 11 partitions for whoknows what.
• Boot Linux with a live USB stick or CD. Shrink the first, large partition using parted. I started out with a 450GB partition that I shrunk to 180. Make 5 new partitions using fdisk or whatever you like for partitioning. I made a 250 MB partition for Linux boot, a 120GB partition for Linux /, a 120GB partition for Linux /home, an 8GB partition for Linux swap, and a 30GB partition for Remix. Use your own judgment.
• Install Linux in the Linux partitions. I use Gentoo, but you can use whatever you like.
• Boot up linux.
• Install Remix OS in the last partition:
  • Download the zip file from this thread. Unzip the file; it contains an installer for Windoze(<somethingorother>.exe), and an .iso file. Make a temporary directory
    
    Code:

    ---

    mkdir /mnt/tmp

    ---

    and mount the iso in it:
    
    Code:

    ---

    mount -o loop <name_of_iso>.iso /mnt/tmp

    ---

  • Format the Remix partition, mount it, and copy the files in the iso to the Remix partition (in my case it is /dev/sda17):
    
    Code:

    ---

    mkfs.ext4 /dev/sda17
mkdir /mnt/remix
mount -t auto /dev/sda17 /mnt/remix
cd /mnt/tmp
find . -xdev -depth -print | cpio -puvdm /mnt/remix

    ---

  • Make a grub menu entry for Remix OS in /etc/grub.d/40_custom:
    
    Code:

    ---

    #!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
menuentry "REMIXOS Resident Mode" --class android-x86 {
    insmod part_gpt
    search --file --no-floppy --set=root /system.img
    set root=(hd0,17)
    linux /kernel initrd=/initrd.img quiet root=/dev/ram0 androidboot.hardware=remix_x86
    androidboot.selinux=permissive quiet SRC= DATA=/ CREATE_DATA_IMG=0
## VGA=791
    video=uvesa DPI=96 UVESA_MODE=1280x800
    initrd /initrd.img
    }

    ---

    You may need a different VGA= or MODE= depending on your monitor.
  • Make a data directory. For some reason it doesn't get created automatically:
    
    Code:

    ---

    mkdir /mnt/remix/data

    ---

  • Assuming grub is installed, make the grub menu and finish up.
    
    Code:

    ---

    mount /boot
grub2-mkconfig -o /boot/grub/grub.cfg
umount /boot
umount /mnt/tmp
umount /mnt/remix
rmdir /mnt/remix

    ---

• When you reboot, you will see two entries for Chrome OS, generally listed as "Unknown Linux Distribution". Either one will work to boot Chrome.
• Follow the directions in the Remix thread listed above on how to enable the Google Play store on Remix.

Took me a lot of trial and error. Hopefully it will be easier for you.
