I have two hard drives on my computer. One hard drive (Master) has Windows XP Home Edition and the second hard drive (Slave) has Windows XP Professional. How can I get the black screen where I can decide which OS I want to be on without opening my computer and changing the jumpers from Slave to Master?
Do I leave the jumpers alone or do I change them both to Master for the dual boot?
Leave the Master/Slave jumpers alone - edit Boot.ini to reflect both OS. If both OS were installed on your pc the necessary Boot.ini entries should have been created during the install. If you have simply added a system drive from another pc it probably won't boot.
