[SOLVED] My m.2 ssd won’t work anymore

[ironmaster]

I built my pc a couple days ago and I had installed one of the new M.2 ssds and had it as my only ssd. Up until this morning, the system was working perfectly fine and running my games really well. I added a new 2.5”ssd yesterday and messed around in my settings(not really sure what I was doing tbh) to get me system to also recognize my ssd. Now this morning, every time i boot my computer on, it keeps telling me the same message: “an operating system wasn’t found. Try disconnecting any drives that don’t contain an operations system.” Even after unplugging the 2.5” ssd, this error message keeps coming up. Any ideas what to do?

Did you check the boot order in the bios?
The new SSD you installed could've changed the boot order to it, and it does not contain windows.
Check your boot order I would say it might be changed.
