Oops!
See if you can restart the install, either from CD or USB

Sorry to whoever I've stolen the following chunk from:

Mac keyboard, maybe Ctrl+Option+F4) after the GRUB step to see the errors

For GRUB errors I really really need the logs. I bet it's looking for a
partition that you blew away earlier ;)

Definitely don't mess with LILO.
