Where you trying to do a dual boot with XP and Vista, with XP on a separate drive or partition? If you were then doing steps 7 on in METHOD TWO of this tutorial may help.
If you installed XP on top of your Vista, then you can do a factory restore to reinstall your Vista back like it was the day you got it.
Reboot the system and press ALT+F10 every second during the POST to start Acer eRecovery Management.
Select Restore system to factory default.
The wizard will lead you through formatting the designated drive and installing Vista.
