The computer was in fine shaped before I put my trial-and-error skills to work, as I always have and sometimes, ends things in catastrophe. Well, I've really done it this time.

I originally was trying to fix my CD-ROM drive. The computer was simply not detecting its presence although the hardware itself and drivers for it are intact. I got onto and found a post, explaining that it was a registry problem. The poster said to go into regedit32.exe, and delete the Upper and LowerFilters on my system's ControlSet blah blah blah. I did so, and in turn, retarded my computer. It would start up just fine, and once the OS booted up, and the desktop was showing, the computer would freeze.

Figuring I could do nothing but format (I tried Last Known Config, simple registry repair), I went into Safe Mode, tried Removing Microsoft Windows from the program screen. It would not allow me to do so.

I then went into Command Prompt and Formatted C:, only, it would goto 99% and stop.. I used my Windows XP CD to boot from, reinstall Windows and use the CD's Format option... still, only to 99% and never finish.

After these impulse actions, I'm left with that error message stated above, no matter what mode (other than occasionally letting me in when I boot from CD). The autochk function was probably deleted in the partial format and Windows removal. When the CPU allows me on to the Windows CD, i can enter Repair mode, which brings me to a command prompt C:\WINDOWS, but, i am only so computer literate that I am not sure how to create a new Autochk or what ever it is that needs to be available in order for my computer to atleast boot up with a clean slate.

But now, I'm thinking maybe I have ruined it? If anyone is able to type me through this, I would greatly appreciate it. Free but hard worked-for help is much better than easy expensives.

Your post is a mess. I have no idea where your current Windows installation stands?

Just boot off the CD & reinstall XP using the repair install method.
