Ok it's been awhile since I had to go through this....I had the same problem. I think you have to put your hd number in and then enter. for me it was the number 1 and then i hit enter. Try 0 and enter....if doesn't work then try 1 and enter. One of those should work for you......fingers crossed and good luck
OP has to g to the second
repair console. He will have to select 'install' windows, then at the second
repair console select repair from there. The password for XP at the first repair console to command prompt is simply to hit the 'enter' key. The link with the instructions I posted are what OP needs to do to do a repair install.
