Service Pack 2 Issues

I recently downlaoded the SP2 for my comp and when I rebooted all I got was a black screen. The only thing I could do was move my mouse around the screen. I called Microsoft and they have no answers (shocker). I tried to boot up in safe mode and the same thing happened. BLACK. I cannnot get the op system to load at all. It shows the boot screen loading, but as soon as that's done, nothing. Black, abyss, emptiness. Can anyone help me get back up.
A friend of mine said to install another hard drive and make it my primary and the original one my seconday, so I can at least access what's on my PC. Can this be done? If so, what do I need to do?

thanks in advance

Scroll down to the recovery console method.

 

Thanks for the link, but it can't be done. I can't even boot up to windows to get to my start menu. I tried putting in the boot disk to re-enter windows fresh and my system would not read the disk. Microsoft said something about the bios not reading the disk. Am I screwed?
All I want to do is just be able to access my content on my hard drive.

 

your friends suggestion of putting another Disk Drive in the system as the primary drive and your current (problematic xp install) drive as a secondary. Install windows on the new drive and you should have no problems getting to your data.

 

Thanks for the info. Gonna try the hard drive method. If all else fails at least I'll have a nice new shiny hard drive for my new PC.
