I have a 11.10 system was running 11.04 without any problems, which I upgraded to 11.10.
I noticed that there were many extra kernels that it wasn't using, so I removed all of them other than the 18.104.22.168 that it was using.
Since then the system will not boot. It stops just after starting Grub with a flashing cursor. If I hold down Shift, then it also displays "Loading Grub" and then hangs.
I have attempted all the Grub repair procedures using update-grub, grub-install from the Live CD and the Parted Magic CD, and using the Boot-Repair utility, etc...
Last night, I even completely reinstalled 11.10 from CD with a full repartition of my boot disk.
I'm at my wits end and don't know what to do.
I can think of only two more things to try:
- Use 'fdisk' to see if the drive is bootable, or
- buy another system.
