Al,
First, please make use of backup software & offline backups to CD & DVD, and disk imaging utilities. {Programs like Acronis True Image, Drive Image, and, BootitNG}.
That way you have a good way of going back to a known good image.
Your situation calls for a note of caution. You & the other party would be breaking licensing terms. You can make a backup copy of "your" CD, and not someone else's.
Here is an alternative, but your system would need a diskette drive. A bootable diskette drive.
The XP setup diskettes can be used to bring up the Recovery Console, if needed.

{The site requires login with a Passport account}.
You need to do 1 download. Follow instructions. This process makes a set of 6 diskettes
Get the version that is proper to your edition of XP, and to the service pack on it. (e.g., if your Windows is on XP service pack 2, get the set for service pack 2. Also, if you have Home edition, get the one for Home).
(It goes without saying, you need to do the download & create the diskettes on a working pc).
Obviously, you need to mark each diskette (1 to 6) so you know which is which. <g>

When you do log in to Recovery Console, & run CHKDSK ---it ** will complain ** about "missing AUTOCHK.exe".
This is where you point it ---you'll need to type it ---
C:\WINDOWS\SYSTEM32 (then press Enter-Key)
Note: Your pc may have Windows at \WINNT .... if so, point to C:\WINNT\SYSTEM32
To exit the Recovery Console, use the EXIT command.

== Also keep this info handy
The MS Knowledge Base article noted below, may help in restoring a "prior XP
System Restore point", in the case where you are unable to do this from a
Windows session. This article describes how to start the System Restore
tool when you are unable to start your Windows XP-based computer normally or
in Safe mode.
You may be able to do it from a "special command prompt"... "Safe Mode with Command Prompt".
It would seem the requirements would be:
1. You had restore point(s) from before. (Which also means System Restore is active on your XP.)
2. You have to be able to "selectively" bootup your pc into "Safe mode with command prompt".
3. Follow the directions to use "rstrui.exe" the XP System Restore program.
