ubuntu & andrioid grub problems.

[rhcm123]

Hey all,

i just felt like trying out an install of android on my netbook to see how its going. i resized my ext4 partition and created a new one for android then installed it, done. however, i wasn't able to setup grub (lives in the ubuntu partition) to see the android partion. Im very bad with grub2 so i need some help.

These are the lines android supplies for grub:


default=0
timeout=6
root (hd0,2)
splashimage=/grub/android-x86.xpm.gz

title Android-x86 1.6-r2
kernel /android-1.6-r2/kernel quiet root=/dev/ram0 androidboot_hardware=eeepc acpi_sleep=s3_bios,s3_mode SRC=/android-1.6-r2
initrd /android-1.6-r2/initrd.img

title Android-x86 1.6-r2 (Debug mode)
kernel /android-1.6-r2/kernel quiet root=/dev/ram0 androidboot_hardware=eeepc acpi_sleep=s3_bios,s3_mode DEBUG=1 SRC=/android-1.6-r2
initrd /android-1.6-r2/initrd.img


i put these lines in /etc/grub.d/40_custom:


#!/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 "Android-X86" {
set root (hd0,2)
splashimage=/grub/android-x86.xpm.gz
kernel /android-1.6-r2/kernel quiet root=/dev/ram0 androidboot_hardware=eeepc acpi_sleep=s3_bios,s3_mode SRC=/android-1.6-r2
initrd /android-1.6-r2/initrd.img
}
menuentry "Android-X86 DEBUG" {
set root (hd0,2)
splashimage=/grub/android-x86.xpm.gz
kernel /android-1.6-r2/kernel root=/dev/ram0 androidboot_hardware=eeepc acpi_sleep=s3_bios,s3_mode DEBUG=1 SRC=/android-1.6-r2
initrd /android-1.6-r2/initrd.img
}
#!/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 "Android-X86" {
set root (hd0,2)
splashimage=/grub/android-x86.xpm.gz
kernel /android-1.6-r2/kernel quiet root=/dev/ram0 androidboot_hardware=eeepc acpi_sleep=s3_bios,s3_mode SRC=/android-1.6-r2
initrd /android-1.6-r2/initrd.img
}
menuentry "Android-X86 DEBUG" {
set root (hd0,2)
splashimage=/grub/android-x86.xpm.gz
kernel /android-1.6-r2/kernel root=/dev/ram0 androidboot_hardware=eeepc acpi_sleep=s3_bios,s3_mode DEBUG=1 SRC=/android-1.6-r2
initrd /android-1.6-r2/initrd.img
}


then i ran update-grub, but the new options didn't show up

where did i go wrong

Old grub counts partitions from 0, where grub2 counts starting at 1.
root (hd0,2)
becomes
set root = (hd0,3)

Grub2 also seems to use linux in place of kernel.

Do not know about splash image - Is that still a valid keyword?

Besides converting the old grub menu to a grub2 40_custom entry, you can install old grub to the Android partition and chainboot it. You have to have grub in the partition for chainboot to work.

Did you try changing the set root = (hd0,3)? I do not see it in your boot script? The script also does not show the kernel & initrd, but may not. Confirm that they are really there.

menuentry "Chainload Other Systems Grub Menu on sda3" {
set root=(hd0,3)
chainloader +1
}

i try and solved with this (http://www.franklinstrube.com/blog/dual-booting-ubuntu-netbook-remix-and-android-x86-on-an-asus-eee-pc/):D
