Hi,
There's a recent grub update, from version 1.99-17 to 1.99-21. I've tried to recover the system doing grub-install and grub-update, even though those commands ran successfully grub keeps telling me that it can't find the root partition when trying to boot.
As i'm using a macbookpro I can't install grub on the MBR but grub-install -f /dev/sda4.
Any thoughts?
