Question Upgrading CPU and replacing my second M.2 ssd with a newer one, can't find my old m.2 ssd in bios

[Can_S]

First ever post and english is not my first language. I can't seem to boot up windows from my first m.2 SSD after replacing my old second m.2 SSD, so I installed windows on my new second m.2 SSD. But i can still see all the old files and windows setups of my first m.2 SSD, that i want to keep. My old second m.2 SSD did not have any windows on it. I'd also rather just boot it from my first m.2 SSD. and use the new second m.2 as extra storage.

I think it has something to do with the new cpu and bios updat i did for said new CPU, could anyone help or explain the reasoning behind this issue?

Probably bootloader was located on the drive, you replaced.
After you replaced drive with bootloader, pc was not bootable anymore.

Anyway - connect all three drives. Boot into windows and show screenshot from Disk Management.

Also list specs of your system and all storage devices.

I can't connect all three drives because my motherboard only has space for two slots nvme ssd's, but here are my specs:

Ok ..
then boot with
#1 SSD and new #2 and show screenshot from Disk Management,
Then boot with
new #2 and old #2 and show screenshot.

What are capacities of all those drives?

BTW - you could install third M.2 drive by using M.2 pcie adapter.
