Ok, here we go...
I am running WIN XP SP3 which is an old original copy of windows xp that has been upgraded via downloads over the years which means my original disk is just win XP with no service packs.

i had a problem yesterday where my puter would not recognize my PS2 keyboard (i know, i need to upgrade to a USB and i am going to) so i rebooted the computer to try to get it working. well after a few attempts of trying to get it to work i get this message

unable to start windows due to missing or corrupt:
windows\system32\config\system file.

Here is the Wrinkle:
after resetting my BIOS to boot from CD and installing my original XP cd into the drive and letting it load i hit "R" to start the repair program and it brings up the question of which Windows operating system i want to repair and it type in "1" because that is the only operating system on my puter and then it doesnt do anything. i know the next step should be that it asks for admin password but it doesnt. and thats were i am stuck, i tried this several times after reboots with no change. i then decided i would just reload the OS and the disk wouldnt do that either.

So here are my questions:
1. since the disk is an original XP with no SP's would this keep it from working on my OS since its up to date and the CD is not?
2. i have read the online steps to recover the REG HIVES but since i cant get the repair console to load is there another way to replace the corrupted file?
3. is there another way to get a Command/DOS prompt where i can do it without the repair console?

yep...

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

well my computer is back up and running. here is how i did it.

I have a friend who had a copy of Koppix 5.3.1 that i used as a boot up disk and copied the system file from the repair directory after deleting the system file from the windows/system32/config directory. the computer then went thru finding all the hardware again and loading the needed drivers for them. the only thing that didnt recover was my Norton 360 program and i was unable to delete it and reload so i had to have Norton load a removal program on my computer and then reload it. i actually think my computer is running cleaner and faster now than it was before. all in all i think i spent a total of 2 hours fixing everything once i got the computer booted using Koppix.
