Well, Im now on my laptop. I restarted and went into BIOS to see if it was there, and it wasn't. When I exited BIOS, it wouldn't boot. It stated that there was no boot drive, even though my SSD C: is the first choice (actually the only boot priority).
No idea what is happening. Gonna open it to see if the cable is out or something.
Opened it and checked. The cables seemed allright, but I tried to tighten it a little bit, but don't think it was that. However, when I started it again, everything was all right again, and D: is back.
Is there anything I can do to make sure this doesn't happen again?
And another thing, it seems like it's slower to start, the MOBO logo in the beginning is there much longer now.
