Hi Guys,
I did a cursory search on this issue and couldn't find a solution to this exact problem I am experiencing. I posted this on the ASRock forums too but it went ignored.
Here's the story:
I have an ASRock Z170 Extreme6.
Currently, all of my non-media files (OS and games) reside on a SanDisk 256gb SSD.
I recently purchased a 970 EVO NVMe M.2 SSD on a really good sale thinking it would be an upgrade.
My idea was to clone my existing SanDisk SSD to this new one.
I finally got around to installing the M.2 SSD a couple of days ago. As you can probably guess, I ran into some issues.
After I installed the M.2 SSD into its slot, it appeared in my list of bootable drives in UEFI, HOWEVER, my SanDisk disappeared form that list.
I freaked out and eventually read on the ASRock forums that the PCIe M.2 slot shares the SATA3_0 and SATA3_1 bandwidth. I got stoked thinking I just solved all my problems. I opened up my case again and switched my old SanDisk SSD to SATA3_3.
That did nothing. The SanDisk was still not listed as a bootable drive. The system browser in the UEFI saw it, but it wasn't listed as bootable. For whatever reason, my regular media HDD was listed as bootable just fine, though.
As soon as I removed the M.2 SSD, I was able to boot from the old SanDisk SSD in SATA3_3.
It seems like installing the M.2 SSD somehow overrides my existing SSD? I hope all of this makes sense. Any and all help would be GREATLY appreciated.
Sincerely,
Pants
