I recently accidentally deleted my Ubuntu partition. When I rebooted the computer, I got the dreaded
grub rescue> prompt. I thought, "simple fix, boot an ubuntu CD and add a new MBR". However, my BIOS will somehow not let me access any menus with any keys specified by my PC manufacturer (MSI). I think this is something to do with a fast boot mode or something, because I don't see a MSI logo on boot, so it may be skipping POST.
I need a way to boot an Ubuntu LiveCD from grub or to boot the Windows partition. Nothing I have tried have worked. I tried listing the contents of all the drives provided by "ls", but GRUB can't read any of them.
