OK. I purchased a Dell Precision m7710 mobile workstation with a 500 GB mechanical drive, running Windows 10. I created a recovery drive to a USB stick. I then installed all my programs. After that, I installed a 500MB m.2 SSD drive in one of the available slots. I cloned the hard drive to the m.2 drive, and I replaced the mechanical SATA drive with another larger, blank mechanical drive. The intent here is that I have both a recovery drive and a fully functional backup hard drive with all my programs installed in case of a failure.
However, now when I boot, it goes into repair mode, and brings me to repair options. I can say boot from device, and specify the SSD, and it boots normally from there. So my thought was to boot my recovery drive USB stick and use Repair Startup. Problem is that when I do that, instead of listing Windows 10, it lists ONLY Windows 8.1.
At this point, I am stuck and would appreciate any suggestions for next steps. Thanks.
