I recently created a partition for XP in order to run some programs i wanted to run and the creation and installation went well. However, when i restored my GRUB, i cant get onto my XP partition anymore. It gives me Error 21: Selected disk does not exist. I think the fact that BOTH partitions are on the same HD, as I only have one, has something to do with it. can anyone help?

Here is my sudo fdisk -lu

title Windows XP (hd1)
root (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

title Windows XP (hd2)
root (hd2,0)
map (hd0) (hd2)
map (hd2) (hd0)
chainloader +1


I actually have 2 like that haha. It looks like the second one is completely wrong because i dont have a second HD
I think i maybe set it to a nonexistant hardrive? should it be (hd0,?) maybe (hd0,2)?
