GRUB loading error

[xenogizmo]

Hi,

I'm a Linux newbie, and I just setup a dual boot of Windows Vista and Linux Ubuntu 9.10, it was a clean install and I ran both OS's for a day without incident. This is on my Dell Inspiron.

However, after restarting my computer I got the following error:
"GRUB loading.
the symbol "b_dd?nit" not found.
Aborted. Press any key to exit"

Any help how to solve this would be greatly appreciated!
Thanks

This sounds like a BIOS problem that is being corrected by the BIOS reinitializing itself on Ctrl-Alt-Del. Check the BIOS to be certain it correctly reports the size of the hard drive. At the right end of the line which gives cylinders, heads, and sectors, there is a field to change from NORMAL to LBA. Something like the disk addresses being incorrect the first time. Have you got something like a PCI secondary IDE controller with its own BIOS extension on it?

Grub error can be found due to one of the following reason:

1. Hard Disk Error
2. Floppy Error
3. Read Error
4. Geom Error

So, check them all and then you can able to solve your problem.
