I'm running Ubuntu 12.04. I installed Ubuntu from USB using the 64-bit iso.
After realising my graphics card was not properly supported in EFI mode I tried to switch from grub-efi to grub-pc.
I ended up not being able to access the grub menu. Output from boot-repair is shown below:
I discovered that I could boot Ubuntu from a grub-recovery cd using the following commands:
set root=(hd0,4) linux /vmlinuz root=/dev/sda4 ro initrd /initrd.img boot
Does anyone know how I can get grub to boot off my hard drive?
