I have debian dual boot with windows and try to install prime os also, while install it i didn't install it's grub because i have debian grub, but after installation i can't found it in grub .

result in fdisk -l /dev/sda2 112687104 133169151 20482048 9.8G 83 Linux i try to install grub-customizer and add it by code

set root='(hd0,2)'
search --no-floppy --fs-uuid --set=root e5d445e4-f59f-5158-b9c7-465f7009bc23
linux android/kernel root=UUID=e5d445e4-f59f-5158-b9c7-465f7009bc23 quiet      androidboot.hardware=generic_x86 SRC=/android acpi_sleep=s3_bios,s3_mode
initrd android/initrd.img

then it was added successfully but when i open it it's show

android/kernel not found
file located at partition `PrimeOS/android/kernel

screenshot for partition details
partition details


from debian add the android entry to /etc/grub.d/40_custom

menuentry 'Android' --class android --class android-x86_64 --class gnu-linux --class os { set root='(hd0,2)' linux /android/kernel root=/dev/ram0 SERIAL=random logo.showlogo=1 androidboot.selinux=permissive quiet DATA= USB_DATA_PARTITION=1 initrd /android/initrd.img }

update the grub

sudo update-grub

according to this configuration your android root dir should be "android" inside the hard drive

in other words you still on debian mount /dev/sda2 to /mnt and check what's inside you should see "android" folder containing ( data initrd.img kernel ramdisk.img system ) ,

else you'll know what to do either rename your android root dir or deplace it depends on your case.

  • How to do that if you want to add PrimeOS and also Bliss OS?

  • just clone the same entry and change root=(hdX,Y) in case they are in different partitions , or just kernel & initrd paths , also menuentry name menuentry 'PrimeOS' .... menuentry 'BlissOS' .... N.B: (hd0,2) means 2nd part on first hard drive

  • It's what I did. But only PrimeOS boots, and Bliss was booting before adding PrimeOS. It's like if only one could boot. superuser.com/questions/1549073/…
