I installed Windows 8.1 Enterprise x64 with latest UEFI. The OS ran smoothly, as expected. Some weeks later, I disconnected my HDD that had the above said OS, connected another HDD to the same SATA port to experiment with some Linux distros. After some time, I re-connected the former HDD to same port, but found that I could not boot into Win8. I tried to repair Win8 boot by running (in UEFI) installation media (USB), selecting boot repair, but only to find that it "could not repair boot". Can someone please guide me what's next to try?

Hey there, 4sure!
This seems like quite the frustrating issue! I'd suggest you to try fixing the issue through Command prompt using the Windows Installation media. There you have System Recovery Options, right? So open it and select Command prompt
When the cmd dialog opens type these commands:
bootrec /FixMbr and hit Enter
bootrec /FixBoot and hit Enter
bootrec /RebuildBcd and hit Enter
Hopefully this will fix the issue! Let me know how it went!

Thanks for reply. As advised, I ran all these commands, with no success. The command "bootrec / RebuildBcd" also runs "bootrec / ScanOs" which reports "0" OS found. Now that's strange! Incidentally, I had the same OS installed on another HDD with non-UEFI mode. Now whenever I connect this HDD, there is no boot problem of any sort! The issue seems to be specific to GPT.

I'm glad that you are able to use your system at least. However, I'd recommend contacting the motherboard manufacturer's tech support and let them know about the UEFI mode issue. They might be able to provide you with some troubleshooting tips or even a replacement if the mobo is still covered by the warranty.
Best of luck!
