Error 13 : Invalid or unsupported executable format

[Creptio]

Ok, I know that this issue has been posted many times. I've been through alot of those threads and I still cannot fix my issue. I installed fedora after windows XP about a month ago, everything works fine on fedora except I can no longer boot into windows.
I get this error: Error 13 : Invalid or unsupported executable format

here is the output to fdisk -l:

# fdisk -l

Partition table entries are not in disk order

and here is my menu.lst:

Once again I'm sorry to repost something like this, I was just completely stumped. Thanks in advanced.

Any suggestions? i really don't want to have to reinstall XP, all the things i had on it and risk it removing grub completely...
