I have been setting up a new hard drive so I have been going from the old one to the new one after shutting down. Last night after I shut down and changed the cable it would not boot. The manufacture's splash screen comes up and then it goes to the black screen with the blinking curser where it just sets the curser does move down the screen about an inch but then just sets there. I put my Windows CD in my DVD drive and tried again to see if it would boot to the CD no go, move the CD to my CD drive and it saw the CD and asked if I wanted to boot from it I let it time out, It then booted normaly. It will not bootup without the Windows CD in the CD drive, I just let it time out and it boots. Any Ideas as to what could make it do this it does it regardless of which Hard drive I have hooked to the machine.
