I had Backtrack5 in dual boot with Vista home edition. I deleted the BT5 partition and now I get Grub error. I have not got a live cd and only a burned Vista CD. i do have an original Windows XP cd though. when I boot from cd (the burned Vista disc) nothing shows on the screen except grub error. Can I use the XP disc to start from scratch on new installation or do a I have to have the live cd or the original Vista disc?
