I'm trying to dual boot ubuntu and xp pro

below is my fdisk print out

Disk /dev/sda: 400.0 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 1 637 5116671 83 Linux
/dev/sda2 638 892 2048287+ 82 Linux swap / Solaris
/dev/sda3 * 893 1275 3076447+ b W95 FAT32

/dev/sda5 1276 12748 92156841 7 HPFS/NTFS

I installed ubuntu first then xp and couldn't get back to ubuntu, so being a newbe I reinstalled ubuntu, now xp won't boot from grub. I had to manually add in the xp option in grub
here is the list from the menu.lst

title Windows XP Professional
root (hd0,3)
makeactive
chainloader +1
