I recently configured a dual boot with Windows XP Professional SP2 and Ubuntu v4.10. I already had XP installed, and I resized my partition using partition magic. Then I installed Ubuntu to the new partition.

When I turn on the computer, if I select Ubuntu from my list of operating systems, it will load just fine. But when I select Windows, it hangs. No errors or anything. Here is the grub config for Windows:

root (hdd0,0)
File system type unknown, partition type 0x7
save default
make active
chainloader +1

I have a picture of the screen it is stuck on, but I cant post a url until I have 5 posts.

Any help will be appreciated!

Assuming you windows is on /dev/hda1, your grub config should be,

rootnoverify (hd0,0)
makeactive
chainloader +1
