Cloning is not an issue (or it seems not to be). After the cloning, I reinstalled the cloned HDD in to the D600 laptop and boot from the OEM Reinstallation CD (for XP Home Edition. When finished, I get the BSOD with the 'fltmgr.sys.....' error.
I have tried the Recovery Console chkdsk/f and /r. I have wiped the to-be-cloned HDD clean before I cloned the Dell 5150 HDD..no joy.
Is it not possible to do what I want to do? Yes, I know, it would be 'swifter' to fresh reinstall and reinstall all the programs affter moving all the data files. But I have a special reason for wanting to be successful doing it the way I proposed.
