I installed Ubuntu 10.04 about a week ago and have been able to dual boot between it and Windows 7 without any difficulty. A few days ago I went to boot windows and it wasn't in GRUB's menu. Per another question, I installed startupmanger, but it doesn't seem to offer any options for adding a new OS.
How do I restore Windows 7 to my GRUB2 menu?
Edit: Given that I don't have a
/boot/grub/menu.lst I'm assuming I'm using GRUB2
