Predator Desktop not recognizing cloned SSD Predator Orion 3000

I have a Predator Orion 3000 that came with a 1TB Intel Optane HDD. I cloned it to a 1TB Samsung Evo SSD using the Samsung Data Clone software. As far as I know, there were no partitions in the original drive, I've done this successfully on 6-7 different computers w/o any issues. But on this one, the computer can't find a boot disk (only the cloned SSD connected). Checking BIOS, I can see the SSD listed only under the peripherals section as connected to Sata 1 port - event he serial no. is listed. But drive does not show up on the boot list under Windows Boot Manager. I tried disabling the boot manager and changing from UEFI to Legacy, I still don't see the SSD in the boot drive list or the general boot order list. Another strange thing I noticed is that after put the original HDD back in and connected the cloned SSD with a USB dongle, computer doesn't recognize the drive. However, the SSD does connect to other computers with the same dongle - I can check and verify that the cloned files are there, including the WIndows System files. It's just bizarre and I don't know what to do at this point. Any tips/help would be appreciated.

I was sure the disabling of the Optane memory and re-cloning was going to solve the issue but it didn’t. What DID solve it was cloning it for the 3rd time with Macrium Reflect. Although the Samsung software had always worked for me in the past, it really failed in this case. Thank you, Macrium!
