Hi, my name is Sam and I have a situation that I have never seen before. I have a Windows XP Pro machine from HP. Apparently, windows became corrupted so I performed a system restore using the recovery partition on the hard drive. The recovery went fine. I then started the normal windows updates. At the end of the updates I restarted the system normally. When it restarted it somehow went to a Windows 8 startup. I have no idea what happened or how this occurred. I know this system cannot run on Windows 8. What I'm trying to figure out is (1) how this happened and (2) how can I get this back to Windows XP Pro. I believe the recovery partition is destroyed because I can't get back to it. I tried to reinstall Windows XP Pro from an OEM disk but now I get a BSOD screen with the code 0x0000007B. In my years of working with windows operating systems I have never seen a situation like this. Does anybody have any ideas as to how to correct this issue. Thank you in advance for your time and considerations.
