XP Pro OS repair from CD

Hi Folks, I have a XP Pro machine that keeps rebooting. I would normally try to repair the OS from CD once I get to that option in the blue screens, but that option is not available. It only whats to let me do a fresh install.

Question How do I repair the OS from the recovery console using the CD?

if you are not offered the option to repair then probably the windows folder is not there. make sure you do not have a corrupt filesystem or faulty hard drive. then you can try to install into the same folder the old windows has been installed.
usually it takes more time to repair than to install new so consider the repair only if there are some special and really hard to get software or user settings

Another cause apart from a corrupt file-system or missing folders (both of which are very likely), could be that your system needs a 3rd party driver for the Disk Controller. For the repair to function in such a situation you will have to put that driver on a floppy disk and press f6 while the CD loads and shows the driver option.

for running diiags :  download ubcd, and run memtest86+ for ram - and disk diag for your disk brand : http://www.ultimatebootcd.com/ 

Then you can run a chkdsk from recovery console : http://support.microsoft.com/kb/314058

you can also do a system restore like this :

----------------------------------------------------------------------------------------------
An easier way is to boot from a Bart PE CD (or UBCD4Win CD) and use the file manager for manipulating files. Here  the procedure :
1. rename c:\windows\system32\config\SYSTEM to c:\windows\system32\config\SYSTEM.bak
2. Navigate to the System Volume Information folder.
it contains some restore {GUID} folders such as "_restore{87BD3667-3246-476B-923F-F86E30B3E7F8}".
The restore points are in  folders starting with "RPx under this folder.
3. In such a folder, locate a Snapshot subfolder. This is an example of a folder path to the Snapshot folder:  C:\System Volume Information\_restore{D86480E3-73EF-47BC-A0EB-A81BE6EE3ED8}\RP1\Snapshot
4. From the Snapshot folder, copy the following file to the c:\windows\system32\config folder
 _REGISTRY_MACHINE_SYSTEM
5. Rename _REGISTRY_MACHINE_SYSTEM to SYSTEM
6. Exit Bart PE, reboot and test

Use a fairly recent restore point from at least a day or two prior to problem occurring .

** you can add the other hives also with this procedure
