Trying to use the BFU to remove Micro Billing Systems. Different methods either do or don't recommend using Safe Mode. When I restart, tapping F8 in the BIOS screen does not give me the option of using safe mode (I am using XP). I have gone ahead anyway and run the BFU. The MBS icon disappears from the desktop during this process. After restarting I thought all would be fine. After about 3 minutes the MBS invoice screen reappears. Arrrrgh! Please help
