Windows 10: Trying to swap boot drive from Optiplex to Precision

I am switching computers from a Dell Optiplex 7020 to a Dell Precision 3431. I'd like to simply swap the C: drive with Windows and all my programs from the 7020 to the 3431. I've done this in the past with optiplex upgrades. But when I put the old drive in the 3431, replacing the c: drive that came with the computer, the 3431 doesn't recognize the old drive as a boot drive. The old drive is visible in Windows and Bios, but the 3431 won't boot from it. Is there a setting I need to change to get the new computer to recognize the older drive as bootable, or do I need to start over and reins

Swapping drive letters, including boot volume

I have a new computer. I want to clone the system to a new SSD. Can I change the drive letter of the SSD to C: after cloning?

I have a new ASUS M52BC with:

• 1 TB hard drive with a Windows (C and empty data (D partition
• Windows 8.1 (I will upgrade to Windows 10 very soon) on the hard drive
• Samsung SSD 850 EVO (physically installed but nothing more done to it)

What I want to get to is:

• 1 TB hard drive with the data (D partition and (for the old Windows partition) the drive letter of the C: changed to something else
• Windows 10 on the SSD as the C:

I don't intend to boot to Windows on the hard drive after I get Windows working on the SSD unless I need to remove the SSD for return to ASUS for repair. (My new computer had a bad motherboard when I received it but I hope I do not need to return it again.)

I want to clone Windows to the SSD using the Samsung Data Migration tool. During the clone, the SSD will of course not have the drive letter "C". To boot from and use the SSD after the cloning, it must have the drive letter "C", correct? I assume the Data
Migration tool cannot change the drive letter used by the software it clones.

After the clone, how do I swap the drive letters? I assume I cannot change the drive letter of the hard drive Windows partition when it was used to boot from because it would be the boot drive, correct?

I know that some people will suggest that I do a fresh install. I want to avoid doing that if possible.

I see
Migrate system partition to a new disk. I think that describes doing what I am trying to do, but unfortunately he does not know how he did it.
