"The Drive Where Windows Is Installed Is Locked" Error And Pc Keeps Booting Into BIOS

[cjoe]

Hey there. First of all, thanks for taking the time to read this. I have a pc that keeps booting into BIOS, there is no option on boot drive priority list, though it can see if I insert a USB. Pc has win 8.1 installed on it and USB have win 8.1 installer. Same happens when I try to setup win from USB, it can't detect any drives where I have to choose one to install windows on. I tried to detect it manually using diskpart through cmd to no avail. When I try to refresh it gives the error in title, and when I try to reset it says the drive is missing. I would like to know if there is anything I can do from here, otherwise I have no other option than showing it to a technician, though I don't want to do that unless it's my last resort(because I don't know anyone reliable, it'll be just some repair store close to my home). Any help is appreciated. Thanks for bearing with me
sorry if selected category for question is wrong, I tried to choose the closest one

Have you tried any of those?

I tried all other than buying their product, which might not work and I can't afford that right now

Your drive might have been locked, encrypted, or bitlocked. This means you cannot enter the drive unless you have a specific access code.

Well, even though knowing the problem means it's half solved already, that doesn't mean much to me unfortunately since I don't know about the access code you mentioned. Nevertheless, thanks for the answer and forgive my ignorance.
