I decided I want to try Linux Mint 12 LXDE on my netbook, but keep Android for convenience.
I installed Mint and Android on separate partitions but of course Mint doesn't show Grub at boot by default, and grub-update doesn't detect Android.
First off, to show Grub at boot I had to follow the instructions on this thread.
Basically you need to edit /etc/default/grub and comment out the line that says
GRUB_HIDDEN_TIMEOUT=0
and then uncomment this:
GRUB_GFXMODE=640x480 (and set your resolution)
before running
sudo update-grub.
Then, to add Android to the Grub choices, you need to edit /etc/grub.d/40_custom and add the following: (Which I found here)
menuentry "Android" {
insmod ext2
set root='(hd0,HERE NUMBER OF PARTITION WITH YOUR ANDROID)'
linux /android-4.0-RC1/kernel quiet root=/dev/ram0 androidboot.hardware=eeepc acpi_sleep=s3_bios,s3_mode SRC=/android-4.0-RC1
initrd /android-4.0-RC1/initrd.img
}
(I changed hardware to eeepc from asus_laptop)
Then sudo update-grub and that should be it.
