try this method :   (not sure why you put it in the Windows7 section)
http://support.microsoft.com/kb/307545
----------------------------------------------------------------------------------------------
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

Have you tried a straight System Restore - from within Safe Mode?

Have you tried last know good configuration under the boot menu  (F8)

If it's XP Pro - use the XP Bootable CD and do a repair - not repair console but chose install then repair - that usually resets enough of the flags and drivers to get you up and working without having to re-install everything. Like alway - It would be worth the time to clone the drive first just to make sure you don't lose any data.

Also - Have you checked the memory with a bootable memory tester - I've seen this loop stuff happen often because of faulty memory
