You don't format harddisks, but partitions. In this case you would want to format your XP-partition, which you can even do from within Ubuntu.
Make sure you have unmounted the XP partition and go to System>Administration>Partition Editor
Select the XP partition and format it as NTFS..

Alternatively, to make your laptop start up with your XP-boot disk: at boot time press the button to switch boot-devices (on my HP it's F9) and select the cd-drive. Boot up as usual and let XP do its work.

You may have to reinstall GRUB afterwards. about which there's about 100.000 posts on this forum...

after you reinstall windows you will need to restore GRUB to MBR of your hard disk. Do this:

1. Boot your computer up with Ubuntu CD
2. Open a terminal window or switch to a tty.
3. Type sudo grub. Should get text of which last line is grub>
4. Type "find /boot/grub/stage1". You'll get a response like "(hd0,1)".
Use whatever your computer spits out for the following lines.
5. Type "root (hd0,1)", or whatever your hard disk + boot partition
numbers are for Ubuntu.
6. Type "setup (hd0)", to install GRUB to MBR, or "setup (hd0,1)" or
whatever your hard disk + partition # is, to install GRUB to a
7. Quit grub by typing "quit".
8. Reboot and remove the bootable CD.

In # 6 use setup (hd0) if you only have 1 hard disk.
