I have an issue where my Asrock z68 Extreme 3 Gen 3 motherboard all of a sudden no longer detects the existence of my Crucial M4 128GB SSD which I have been using as my boot drive for nearly 5 years now.

It was running perfectly fine until I helped a friend test if his GPU was broken.  The video card had to be RMA'ed, and I also tested a working copy of that GPU in my machine that day. I installed the associated drivers for the RX480 (AMD Radeon 16.7.2) and Unigine while testing. 

When I came to turn my PC on later that afternoon, I discovered that my computer no longer recognises my SSD. It does, however, recognise my HDD's perfectly fine. I have tried every combination of SATA port, SATA cable and power cable for each drive, and it consistently only doesn't register my SSD. 

In addition, I have connected my SSD to another working computer, and not only does it recognise it but I can even boot to the copy of windows that is installed on that drive, ruling out the SSD being broken.

I tried using the windows command prompts in the installer to rebuild the boot partition (even though it doesn't appear to be broken), flashing my SSD's drivers and even updating my motherboard to the most up to date BIOS listed on Asrock's website; yet my motherboard will not recognise my ssd. 

I have tried creating a system image of my ssd and attempting to restore the drive from that, but I have got the error saying "This system image was made on EFI, and your computer is using BIOS". 

I'm honestly very confused at this point as to what is the correct path way to getting my ssd to boot on my pc. Any advise is greatly appreciated.

It sounds like your system is set to legacy now and it was set to UEFI previously. Try changing the PCI ROM Priority to UEFI under your Boot section in the UEFI.

My motherboard does not have an option to set it to UEFI mode under PCI ROM priority, but it does have EFI Compatible. I have tried using this setting with no success as well.
