Removing Vista And Its Boot Loader

If you have Vista and XP in dual-boot and want to get rid of Vista, its boot loader is an obstacle. To get rid of Vista, insert your Windows XP CD and boot from it. Remember to set your first boot device as your CD/DVD drive. Press a key when it tells you to during boot up. When prompted, press [R] to load the Recovery console. Confirm your Windows installation by entering the number. Enter your Administrator password at the prompt. On the prompt, type fixmbr and then type fixboot.

Reboot and you should be able to boot into Windows XP. Make sure you have backed up all critical files. Then format the partition on which Vista was installed to clear out Vista. Another way to do this is to insert your Windows Vista CD and boot into Windows XP as usual. Go to Start > Run, type X:\boot\bootsec.exe /nt52 ALL /force. (Replace X with your CD/DVD drive letter). Reboot and format the Vista partition
