After a few hairy moments when neither Ubuntu nor Windows would actually boot, my re-install of Ubuntu has worked out ok.

What did I do different? Well, first of all I created a partition specifically for my /home/ directory. This is supposed to make upgrades easier since I won’t have to redo all my settings and such again.

The problem I ran into was with the famous GRUB startup menu. It wouldn’t allow me to boot to either OS, which of course is a problem.

Turns out all I really needed to do was to edit the /boot/grub/menu.lst and make sure that my linux partition was set to hd0 and windows to hd1. Then things worked out real good.
