dual boot problem
 

Hi ;)
I have dual booted vista and ubuntu, but since my computer crashes when i try any other operating system than vista i desided to delete the partition with ubuntu on. When i restarted my computer i got this error: error: unknown filesystem.
Grub rescue>
Please help!

If you deleted the UBUNTU partition than have to restore Vista boot to MBR .
Do you have A Vista Cd or rescue disk ?
Boot from the rescue disk and and type at the commandline Bootrec.exe/FixMbr
