WindowsSystem32configsystem Cannot Load

Turn it on, and thats when it started I get passed the BIOS and before the Windows Xp loading screen i get this "WindowsSystem32configsystem cannot load, its missing or corrupted yadda yadda yadda.I followed the steps on this guide provided by microsoft, I get passed step 1, but it never asks me any of the Administration stuff. After all the copying and deleting of those files, i reboot. It gets me to windows, but its in 800x600 resolution and blue background . I click start and the top says "owner". I cant run antivirus or anything because it says i dont have permission. So i restart and hit F8 when the screen is at the dell screen loading the BIOS not the windows loading screen, F12 or F2 didn't have safemode as one of the options .The guide said to use F8 so i did) and i get more error messages.Same spot where the first problem started, i get a whole bunch of stuff about my computer and dell. At the very bottom, it says "Keyboard failed" It loads to the next screen where it has the normal menu when you try to enter safe mode and the keyboard seizes to work. I'm stuck at "run windows normally" and none of the arrow keys work.
