OK So to begin Im upgrading from windows XP Professional.. Before I decided to up grade I ran into this error on my PC:
C:\windows\system32\config\system missing or corrupt
I tried the recovery disk and pressing r and typing in the commands in microsofts website and it said: access denied (or something along those lines) Ok so I gave up on that and when I start the computer I can go into BIOS and everything but as soon as it hits the screen where "windows didnt start last time, safe mode, blah, last known good configuration. If select any of them it freezes and if I allow the countdown it usually goes to a white / black screen and says that error up there ^^.
We couldnt get it fixed so I decided that I would upgrade to windows 7 and I purchased it online and downloaded it and it WILL not work with the computer. I go into BIOS and set CD/DVD first and press a key to boot from disk and it just restarts as soon as it loads and keeps redoing it. Occasionally Ill get a " the file is possibly corrupt, the file header checksum does not match the computed checksum.
