1.) download Bart PE, RunScanner, and FixMoveHD.reg file.
2.) Prepare the Bart PE Recovery CD
3.) Use the new created CD to boot the problem computer
4.)Load FixMoveHD.reg file from PE
5.)Extract 'Atapi.sys,' 'Intelide.sys,' 'Pciide.sys,' and 'Pciidex.sys' to %systemroot%\system32\drivers" folder from '%SystemRoot%\Driver Cache\i386\Driver.cab or sp2.cab'.
In my case (Winxp sp2 deployment) I used the following commands :
expand sp2.cab -f:atapi.sys c:\windows\System32\Drivers
expand sp2.cab -f:intelide.sys c:\windows\System32\Drivers
expand driver.cab -f:pciide.sys c:\windows\System32\Drivers
expand driver.cab -f:pciidex.sys c:\windows\System32\Drivers
6.)Reboot the system to normal mode and it should work fine now

Well, the first thing you need to do is to get the system working again, so, put the system back in the original working configuration. If you changed the motherboard, change it back to the original. If you moved the drive to a new system, place it in the old one.

Now, for people that understand what they are doing, and how to do it, here are the "quick" steps:
1 - Extract 'Atapi.sys,' 'Intelide.sys,' 'Pciide.sys,' and 'Pciidex.sys' from '%SystemRoot%\Driver Cache\i386\Driver.cab' (or SPx.CAB if it exists, where x is the latest service pack)
2 - Copy those four files to the following location: '%SystemRoot%\System32\Drivers' (do not replace files already there)
3 - Merge the registry file found below (copy the text to notepad and save as a .reg file), or better, download it here
4 - THAT'S IT! Move it to the new system (or change the motherboard), and your system should start up.
