If this machine has a recovery partition you can restore it to it's original condition. If it does not, then you will have to install windows again from the installation disks. If it came with no disks then you'll have to purchase the disks. Before you do that see if this computer will run xp by looking to see that it meets the system requirements for that. Good luck.

Try rebooting the computer with the back up disk inserted in the slot. This should work because the computer looks at all the disk drives when it reboots. And should default to the backup disk. :)

you cannot get a new registry, this is formed by the o/s as it is installed and contains all the information regarding your installation. if you are getting a corrupted registry message, the system places a copy on your root drive which the system should access on its own, so if you are getting this message, try your recovery disks. Stick em in the optical drive, set that drive as the first boot device and reboot the machine. When it asks if you want to boot from cd/dvd, press any key or answer yes and let the thing load.. Then use the recovery option in the menu that appears..

u have to format the hard drive and then installing windows, if the problem persist, it has to do with *********** board.

Try using the instructions here from Microsoft .. I know you are able to boot but this will allow you to return your registry files

To turn on system restore, go into control panel, system. Click on the system restore tab. There you can turn on your system restore again.

This problem is indeed caused by a faulty MBR but there are solutions other than zero-filling the drive.
If you can get access to a RipLinux CD there is a little utility called Testdisk that will write a new MBR code to the first block of the drive. I just did this on a Sony PCG-K15 this morning (after cloning the drive just to be safe) that was giving the same error of "LOAD ERROR- Press any key to reboot" and it worked like a charm. The machine booted right up.
Hope this helps...
