Grub won't boot Windows XP

[w5ami]

I just installed Ubuntu 10.04 LTS and can no longer boot windows from Grub.

Here is what Grub shows for Windows in grub.cfg:
insmod ntfs
set root='(hd0,1)'
search --no-floppy --fs-uuid --set 69f64f5f4e6215b2
drivemap -s (hd0) ${root}
chainloader +1


Here is the output of fdisk -l

Disk /dev/sda: 250.1 GB, 250059350016 bytes

I hope someone can tell me what I can try. Currently, when I select Windoze to boot, it simply does nothing. No errors, just sits there with the cursor blinking at the upper left.

Thanks in advance.

Hello Brian!

Have you tried repairing the grub?

I saw this guide that seems to be very clear regarding grub2 repairs that ubuntu started to use.

Best of luck!
