I went to my computer the other day and the screen was black. I thought my screensaver was on, but when I went to move my mouse, the screen remained black, but I could still see my white cursor arrow. I restarted my computer, and a black screen came up saying that Windows XP could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM.

At this point I got my OS disc (xp 2000) and put it into the computer, hoping to reinstall the software. When I restarted the computer, it was giving me the same "corrupt" notification, or it was telling me there was a keyboard failure. Every F1, F2, F8, F12 just leads me right back to the black screen with the error message. The OS disc is not running when I put it into the computer. Any suggestions how I can get this darn thing up and running again?

go here..download the following file: rc.iso....then run chkdsk /r
from the rc.iso cd...be sure the bios is set to boot from the cd drive first...

if you don't have a burning program that will burn .ISO files go here and get burncdcc ..a small FAST no frills iso burning program...

NOTE...do not put a blank cd in until burncdcc opens the tray for you
1. Start BurnCDCC
2. Browse to the ISO file you want to burn on cd/dvd ....in this case its rc.iso
3. Select the ISO file
4. click on Start

make sure in the bios the cd drive is the first boot device....put the cd in the cd drive..boot your computer....

boot from the rc.iso cd....
type in chkdsk /r press enter
note the single space before the /

While chkdsk is running, you will see a light blue window with a dark blue band at the top and bottom. Chkdsk will display the specific stage it is checking as well as the percentage of completion of the stage. You cannot do anything else on your computer while chkdsk is running. When chkdsk is finished, it will automatically reboot your computer.
NOTE this can take a long time to complete..it may even appear to hang or get stuck at a certain % for a couple of hours...then complete
it may even back up and go over the same area...this is normal...let it run...there are 5 stages
DO NOT TURN OFF YOUR COMPUTER WHILE RUNNING CHKDSK or you can have severe problems...
nojoy...
boot from the cd again...
then type fixmbr press enter...reboot
no joy ....boot from the cd again...
type in fixboot press enter...reboot
nojoy...boot from the cd again...

Type in bootcfg /scan and press Enter

if it says total identified window installs: 1

Type in bootcfg /rebuild and press Enter...

It will identify your XP installation...type Y once you see this prompt.

You will be prompted to enter the load identifier...type in Microsoft XP Home Edition or Microsoft XP Professional depending on whichever version you have...press enter

You will be prompted to enter the load options...type in /fastdetectand press Enter

Type in exit and press Enter

remove the cd

Reboot

Thank you for the response, but I can't even get onto my computer to burn anything. I am on my work computer right now. Sorry if I seem a little confused, but I am not that great with computers

on some systems ...when you first press the power button it may say press F11 or F12 for boot menu ....on the screen...
others are set in the bios...to get into the bios you start tapping the delete key immediately (about once per second ) after powering up...and search thru until you find the boot order...set it to cd first and hard drive second...save the settings by pressing the F10 key (usually)...but read the screen to be sure
