vista still exists in you BOOT.INI
..
unhide your system files and hidden files then goto C: drive
open your boot.ini in notepad
then copy and paste this into it
Code:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
Btw DONT DO THIS untill some other member verify's it
..
