You can use the manual System Restore method - see here:
http://support.microsoft.com/kb/307545. A simpler method relies on you doing
this:
1. Use a suitable method to access the disk (see below).
2. Create a backup copy of the existing System hive
(c:\windows\system32\config\system).
3. Copy the most recent System hive file from the System Volume Information
folder (as explained in http://support.microsoft.com/kb/307545) to
c:\windows\system32\config.

Here are several methods to access the hard disk while Windows is
inoperative. Here are two of them:
- Remove the disk, then install it in a 2.5" external USB case which you can
then connect to some other WinXP PC.
- Boot the machine with a boot CD such as a Bart PE boot CD. It takes a bit
of time to create such a CD but it is an extremely useful repair tool.

Was this event preceded by a power interruption?

Do you have a bootable XP installation CD, bootable Recover Console CD
(you can makes one)?

hanged. I had to re-boot by holding down the main switch and here we go

XP but it hanged on formating stage after formatting 27%
