There are two possible solutions (depending on the use of the 'clone'):ġ) set the changed disk signature back to the old one Ģ) set the references in the Registry to the new disk signature or remove them and let the system recreate them Įach value in it referring to a volume or to a drive letter residing on a 'hard disk like' device is a hex value made of:ĭisk Signature+Offset to the beginning of the partition, EXAMPLE: The one with the changed signature won't boot, because the OS cannot (in a nutshell) 'find itself'. The sheer moment two disks with the same disk signature are connected at the same time to a NT system the disk signature ot one of the two will be changed. Point being that NO TWO clones can be connected to a WINNT system at the same time. The actual (good ) question is how (EXACTLY) the disk was cloned (IF it was actually cloned)?

If the system loads there are no issues with the active partition. I also F12 booted into BIOS and turned off Keyboard Errors - no help. I was too dumb to mark down the BSOD stop code. Rebooting into 'Last known good configuration' did not help, and I also could not boot into Safe Mode Command Prompt. When I retried in Safe Mode, I saw the drivers load (the vertical list of drivers in white letters against a black background) so I know the machine was able to read the drivers off the WD clone, But again a BSOD. The WD clone would start booting and after the black XP screen with a progress bar would trigger a BSOD. I did the clone with Macrium Reflect 7.2 running on a bootable USB stick, and I had the clone do a 'Verify'. Before I did the clone, I wiped the WD and formatted it for NTFS.

The 'new' one is a classic 500GB WD5000AAKX, which had worked fine in another machine. The old one (currently running) is a 488GB Seagate ST95005620AS, which is also known as a Maxtor Hybrid HDD+SSD. So I put the old one back in and can boot OK. Just spent most of the day cloning my old hard drive in my XP machine to a newer although slightly used one, but when I boot from the 'new' one, I get BSODs.
