I'm trying to use GRUB2 to boot Android-x86. The following menu entry works fine on a ThinkPad 20FR but not 20UB (which it just boots to Android command-line).
menuentry "Android" --class android-x86 { savedefault
set root='(hd0,msdos5)'
linux /android-9.0-r2/kernel quiet root=/dev/ram0
initrd /android-9.0-r2/initrd.img
}
