No.
No.
If no HDD in BIOS, then Windows cannot find it either.
It appears that your HDD has failed.
What work did the Geek Squad do on the system a few weeks ago?
Oh, I was afraid of that.
When I sent it to Geek Squad a few weeks ago, they didn't actually do any work on it. One of the hinges had broken, and so they sent it off for a price consultation. It started slowing down maybe five or six days after I got it back.
HDD has likely failed.
I would suggest that you re-seat HDD and check the cable.
