HELP I had two partitions in my hard drive. With Partition Magic, I deleted Partition C, because I only wanted Partition D. Now my computer doesn't boot, and I get the error message "Operating System not Found" everytime I restart. I tried restoring my PC with the manufacturer's Restore CDs, and also tried installing a fresh copy of windows XP with a new XP CD. Apparently my harddrive cannot read from the CD Rom, or is missing the CD Rom drivers. Anyways, I bought a new CD Rom drive to try to fix the problem, but it didn't work. I also bought a new hard drive, and I am still getting the same message. I need help desperately.
