BIOS problem

[JC8]

not too much of an outcome for you? After the reset either it works or reinstallation after formatting? i will do it

thanks

Well not like you gave a lot of info to diagnose the problem, just that the BIOS isn't showing the drives, so either the BIOS has some config issue, or the drives got encrypted (again), or the Windows boot manager is corrupted, in two of those cases you gotta just reinstall the OS, the boot issues with Windows aren't exactly simple to solve either, usually erasing and reinstalling saves you more time, even if you have to reinstall some drivers and software. My suggestion is that if you want to avoid this, you should use another PC as backup server using some open source backup server software, like UrBackup (i used it a few times and it saves a lot of time when Winblows 10 decides to break for no reason), or either buy Acronis (does the same but it's user friendly), to make backup images all the months.
