The drive 0 is(was) my drive for almost 2 years. My thought was that I should NOT get that drive messed up in the cloning attempt. Drive 1 and drive 2 were also on separate SATA III cables. Unknown to me when I made my drive 0 original disk, is that W10 made it an UEFI GPT drive. It had never given me any trouble in all this time.
Now, since, I had added another bootable drive that is MBR and NTFS, it shows my original drive 0 as three partitions:450MB NTFS labeled as D:Recovery, 100MB FAT32 E: with no label, and the remaining 237GB has NO drive letter. Windows 10 does not recognize the 237GB portion at all. Used AOMEI Partition software to add a drive letter to that 237GB section, and then windows recognizes it. It will not let me view the files or folders, telling me: 'I' is not accessable, access is denied. The drive letter addition does NOT survive a restart...
I used another 3rd party software, and WAS able to read the files and folders on that 237GB section.
If I try and boot off that original drive 0, I get what must be described as a BSOD, that tells me C:\WINDOWS\System32\winload.efi is missing or corrupted. I say it looks like a BSOD because I have seen such a thing before on W10.
I am presuming that AOMEI Backupper changed my drive 0 so that IT would take over on restart (which it did). I do not know how to undo the Backupper mod to my drive 0!!!
