Had a dual boot win XP SP3 and linux system. While trying to remove linux and the partition I deleted the MBR (received grub error 22). I ran a repair of windows via the installation disk (fixmbr and fixboot from the command line). It seemed to go fine other than at the prompt the drive letter was 'D:' Now on start up it goes to a black screen with a cursor and then freezes. How do I fix this?
