Question Installing a second M.2 SSD causes boot failure ?

Feb 14, 2022
GPU: RTX 3080
Mobo: MSI B550-A PRO

So I got myself a second m.2 ssd for some extra storage. Installed it yesterday, and first boot was a fail with the VGA debug light lighting up on my mobo.
So I Restarted and everything worked fine.

Now today, I am constantly getting the boot fail with the VGA debug light lighting up. If I remove the new ssd, everything works fine. But installing it causes the boot to fail. I read my mobos manuals and there is nothing about the second m.2 slot disabling the main PCIE slot, where I have my GPU installed.

Anybody have any ideas why this is and how to resolve this?
