Comment 44 for bug 653134

@Colin,
Confirmed this fix... I changed grub-mkimage back to original, ran "grub-install /dev/sdaY". Reboot, still worked but now I am seeing the "No suitable mode found" messages flash by. Then I run "sudo update-grub" and reboot.... grub prompt.

So, updating wubildr followed by a regeneration of grub will do it.

Then I reapplied the fix, ran "grub-install /dev/sdaY" again - and it works fine again.

So the modules in my /usr/share/lupin-support/grub-mkimage looks like this now...
# Watch the modules order!
modules=" \
    loadenv biosdisk part_msdos part_gpt fat ntfs ext2 ntfscomp iso9660 loopback \
    search linux boot minicmd cat cpuid chain halt help ls reboot \
    echo test configfile normal sleep memdisk tar"
