What caused this error, and how do I fix it?


  • If I use BU, backup, restore, it works with no error. Does not require universal restore. Why would backup restore work, but not clone? I am confused.
  • @AiArtisan, If you don't mind, could you try to do the system clone again via AOMEI Backupper?
  •      I spent 2 days on this. Here are the results.
         In these tests, I used Windows 10 PC internal SSD to external M.2 NVMe SSD to internal SSD. Almost always the 2nd internal disk was on a different PC.
         When using Partition Assistant (PA) in the first clone, it will always fail in the end, it doesn't matter what the 2nd application or setting is. Every other combination of application & settings succeeds.
         The goal is to find what glitch is causing the BSOD result referenced in the original post. The goal is not to find methods that work, I already know many methods that work. Therefore, I did not test BackUpper (BU) system clone method, that was not my goal, the scope is only Disk Cloning method, and the BSOD problem.
         While the chart below always has 3 disks, as you saw in my original post, even if I merely use 2 hard drives, it also results in BSOD BCD error, so it doesn't matter if I clone to 1 disk or 2. In this chart, when the result says "Bad", that means that the Aomei product reported 2 successful clone operations, but after reboot, Windows 10 reports BSOD BCD error. The Aomei products never reported an error in the application or operation. I always used intelligent sector, not exact sector-by-sector method.
         Admin, please send this to your development team, and reply with why the PA Disk Clone method always results in BSOD BCD error on 3 different PCs, and with 2 USB stick methods, thank you.

    Corrected 1 cell.
    Also, the "Windows Installation" at the bottom refers to using PA inside of a regular Windows installation, instead of a WinPE, like the others.

    @AiArtisan, We might need to check and compare the BCD files to analyze the problem. Could you offer the BCD files on the source disk and cloned disk? And, please also offer screenshots of Windows Disk Management so that we check the layout of the source and target disks.
