Based on your latest post, I'll assume the following...
1. You seem to indicate there are two HDDs installed in your desktop PC beside the recently installed M.2 SSD. I suppose one of those HDDs is your boot drive containing the Win 10 OS. You refer to this HDD as a 180 GB HDD. Those 180 GB drives have practically disappeared from the market so I assume it's a very old HDD. Is that correct?
2. I suppose the other HDD has been performing as a secondary drive for storage purposes. Is that correct?
3. You mention then new M.2 SSD contains a video program that plays without problems. So that indicates after you installed the M.2 SSD you began to utilize it as a secondary drive in your system. Apparently at that point you never cloned the contents of the 180 GB boot HDD to the SSD, right? Why did you do that? Just to see if the SSD was non-defective before undertaking a disk-cloning operation?
4. What was the reason you didn't IMMEDIATLY undertake the disk-cloning program?
5. In any event since the boot HDD functions without problems and it appears the SSD has been properly installed, so there would seem to be no reason why a successful d-c operation can't be undertaken.
6. Perhaps you didn't properly use the Acronis program. I'm not particularly fond of that program and it's not the d-c program we generally use. We use the Casper program; the program is a commercial one costing $49.99, however a 30-day trial edition is available from https://www.fssdev.com/products/casper/trial/ so you may want to give it a try. If you want to do so here are some step-by step instructions for using the program...
7. Before undertaking the disk-cloning operation close all open programs. (Generally you need not disable your anti-virus program). ENSURE THAT ONLY THE TWO DRIVES THAT WILL BE INVOLVED IN THE DISK-CLONING OPERATION ARE CONNECTED IN THE SYSTEM - NO OTHER DRIVES.
8. The opening screen of the program will highlight "Create a Bootable Backup". Click on "Add drive" and a listing of the appropriate destination drive(s) will appear, e.g., your M.2 SSD.
9. Click on the destination drive's listing and then the "Back up now" button.
10. Casper will run in the background and alert you when the disk-cloning operation is completed. (You can view the actual progress chart by clicking on the Casper icon in the Notification Area on the Taskbar.)
11. Following the successful disk-cloning operation DISCONNECT the 180 GB source HDD from the system and boot SOLELY to the connected SSD destination drive.
12. Casper will utilize the entire disk-space of the destination drive to contain the total data contents from the source drive.
13. Assuming the d-c operation is successful, work with the SSD for a reasonable period of time to ensure it's completely functional. Only then should you reconnect all your other secondary drives and only then can you feel free to make any changes involving the former boot drive.
