My computer crashed when i installed Service pack 1 for windows vista, i spoke with a Microsoft expert, and supposedly my problem is very rare and the files on my hard drive are now corrupt and i cannot boot the computer. I have very important files on this and the only way to recover the files is to disconnect my hard dive and plug it into another computer as an external hard drive (not quite sure how to do this, i just plugged it in like the regular one was, might have done it wrong). Also, I tried running the computer on an alternate OS but there's some kind of password issue and i cant access the files. I plugged the hard drive into another computer but now i'm having the same problem as before i get a blue error screen. I need to somehow start the computer using the operating system on the working hard drive while still being able the access the files on the corrupted one. How do i do this? or how do i plug the hard drive in correctly in case i did it wrong?
