I've got the same problem today. Seems like grub2 don't like something in its configuration file. I did something like that to boot the system:
sh:grub> linux /boot/vmlinuz-2.6.31-14-generic root=/dev/sda2 loop=/ubuntu/disks/root.disk ro sh:grub> initrd /boot/initrd.img-2.6.31-14-generic sh:grub> boot sda2=(hdd0,2) in my is a windows partition with /ubuntu folder on it. Sure thing, you will have to change your kernel version in files (or just hit TAB to suggestions). To find what drive is what you can use 'ls -l ' command or 'ls (hdd0,2)/' for the content. I've had (loop0) as an image of my linux root folder, supplementary partition (hdd0,1) and windows partition (hdd0,2). This will not solve the bug, but at least you will be able to use OS until it will be solved. It is really disappointing, that this things still happening. After this bug will be gone, I'll definitely disable updates.
