Add PrimeOS to the GNU GRUB bootloader

Solved
Roucoul7424 -  
Hello, I just installed a triple boot Windows / Ubuntu / Prime OS but when I open my laptop and it boots into grub, there is no option to boot into Prime OS

I don't know if you could help me, but Prime OS is installed on /dev/sda2 and I installed the grub customizer application on Ubuntu

Thanks in advance

    Hello,
    It's like with Phoenix OS, you have to add the entry to GRUB yourself.

    The os-prober command in Linux does not detect Android-based systems.

    What should I do if it is already installed
    Because the tutorial says to "install it" on Ubuntu

      @Roucoul7424Have you read the tutorial in the link?

      It installs in a folder in the root partition!
      Follow the tutorial step by step (if needed, use Google for translation).

      Otherwise, adjust the text to add in grub for your installation in a partition, but it's not a sure thing...

      Good luck!

      @jns55Okay, thanks, so basically it's possible but it's more complicated.

      @Roucoul7424It is probably necessary to replace 
      --set=root /primeos/system.sfs
      with 
      --set=root /dev/sda2/???/system.sfs

      and the same goes for the following lines containing "
      /primeos
      "
      Replace ??? with the directory where system.sfs is located (maybe /boot), you need to look in the directory structure.

      In any case, the installation described in the tutorial consists of creating a folder named primeos at the root of the ubuntu partition, decompressing the archive, and copying the obtained folders into it. Nothing too complicated so far; it's the modification of grub that is trickier because it's not obvious that it will work on the first try. I remember testing phoenix os a few years ago and I struggled quite a bit with grub to achieve dual-boot.

      These OSs based on Android or Chrome OS are not designed to be installed in dual-boot with Linux.
