Hi. I have this old desktop that has a18 gb hard drive and is running windows xp. I am running out of diskspace and i have this hard drive at home : A 40.0GB Quantum Fireball Plus AS. I connected it up, set the jumper to slave and restarted the computer. The system bios is recognizing the drive but i am getting an error message:BOOTMGR IS MISSING. Press Ctrl. Alt. Del. to restart ???Can anyone help with this matter please? Thanks a lot.
