download RC.iso from the following link:http://www.thecomput...edic.com/rc.iso
You need to burn this image to a CD and boot your computer with it--this is different than burning a file to a CD. If you do not know how to burn an ISO image, then download the following program to another Windows XP machine, install it.
make certain you download the proper installation for your version of windowshttp://isorecorder.a...isorecorder.htm
After installation, right click the RC.iso file you downloaded above and choose COPY IMAGE TO CD.
Then reboot your broken PC with that CD in the CD-ROM drive.
This will give you a recovery console to use to run
Insert the CD in non-functioning CD, set the PC to boot to the cd-rom first in the boot order section of bios (get there by pressing f1,f2, or del depending on machine while memory is counting up)
When boot begins, a windows setup will appear to start, but you will be taken to a recovery console. You will need to select your windows installation by pressing a number, then typing in the administrator password, which is blank for XP Home or whatever you set when you installed your machine for XP Pro.
After entering the password, you will find yourself at a command prompt
copy C:\WINDOWS\ServicePackFiles\i386 c:\windows\system32
Eject CD and reboot...
