XP not booting

[pwolschen]

I installed ubuntu 8.04 on my computer running XP. i wanted to make it dual boot. When i start the computer it gives me an option between linux and XP. linux works fine but when i attempt to start windows nothing happens. This is what sudo fdisk -l brings up.

Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda2 29253 30401 9223200 c W95 FAT32 (LBA)
Partition 2 does not end on cylinder boundary.
/dev/sda3 14194 29252 120961417+ 5 Extended
/dev/sda5 14194 28899 118125913+ 83 Linux
/dev/sda6 28900 29252 2835441 82 Linux swap / Solaris

What can i do to fix this?
