OK, so now a different issue... I don't have the Lenovo base, so I'm trying to install Ubuntu using the netboot method. No luck: the GRUB menu won't come up at all, and it loads straight into Windows. Suggestions? I've tried alternating between (hd0,0) and (hd0,1) in the menu.lst file. Also, my c:\boot directory already existed, and it was actually "c:\Boot". Might GRUB be case-sensitive?
