swapped SSDs, now PC won't boot to Windows

[scubaslim]

So this is a head scratcher for me...

All I did was swap a secondary SSD in my rig for a new/bigger one. Now my PC won't boot to Windows at all. I've now disconnected everything except my GPU and my Samsung 960 EVO m.2 (which is what has my Windows on it).

It just boots to BIOS now and doesn't even detect my m.2 drive. I could really us some help.

Thanks

Put the original SSD back. And post screenshot from Disk Management.

I've tried that. Nothing will get me to boot to Windows

However, I did re-seat my m.2 and it shows up BIOS now, but won't boot up

Change boot priority options in BIOS to settings they were before replacing SSD.

I already tried that... I'm just going to try reinstalling Windows. luckily MOST of my stuff is on other drives... what a bummer

Try all the boot options available.
How many SSDs/HDDs are there in your system?

Normally, what happens windows uses one of the previous windows installed disks. Only from experience I am assuming you migrated windows to your M2. Then it was still reading from the old SSD to make windows boot on the M2. When you removed it, it wasn't prepared for that.
