@patts:
GRUB not loading the boot-image can happen for a number of reasons. It did install though, as you got an error message.
It seems that it might be looking at the wrong partition for the linux boot image.
I don't know how well you know Linux, but GRUB will give you a minimal command shell. You can find information on available commands here:
http://www.linux-sxs.org/administration/grub-cmd.htmlIt may also fail because your PC is set to handle a large harddisk as "LARGE" in your BIOS instead of "LBA". Try changing that setting.
Hope this helps a bit...
