Unable to access BIOS on my Aspire V5

Hello everyone,

my problem is a little more complicated than the title suggests. Indeed, it dates back to two weeks ago after I installed a Bluetooth driver that was supposedly compatible with my PC but still caused it to crash. This led to long hours of waiting for my PC to respond before it crashed again, displaying beautiful blue screens with "Critical Process Died." After managing to boot into safe mode, I tried to uninstall the problematic drivers, but nothing worked. I ran several "chkdsk /R" commands that allowed me to recover my desktop, but the performance was reduced; I could only open two applications at a time without my PC displaying a blue screen. This brings me to the source of the problem I am currently facing: I noticed that at startup, the F2 key that used to allow me to access the BIOS a few days earlier no longer worked, and the startup went directly to the login page. I thought it was nothing serious, since a simple "shutdown -r -o" allowed me to access it. However, I recently reinstalled W10 using the Windows Media Creation Tool (very handy) and managed to get a functional W10 back. Except that recently, I wanted to test a Linux distribution that I installed on my USB stick to use by booting from it. I changed the boot order in the BIOS to boot from my stick and accessed my Linux. The problem now is that I am unable to return to Windows because my PC boots from my USB stick even when I remove it!!
I hope I have been clear enough; I took the time to explain my situation before the W10 reinstallation to perhaps give some people a clue, just in case.
Thanks in advance.

Configuration: Linux / Firefox 45.0

Hello Melissa6969,
When I remove my USB key, the PC tries to boot and I get a black screen that says "Operating System not found."
My F12 key is also functional and it's the one I need to press, but when I press it, nothing happens (even when tapping it).
I'm trying Linux in Live, I boot in legacy and secure boot is disabled because otherwise it wouldn't boot the Linux distribution.
Finally, my PC was running Windows 7 before.

A Windows 7 with UEFI BIOS and Secure Boot, that's rare indeed.
What brand is your PC??
One that you built yourself?

And if you go into your BIOS via F2.
And you reset your BIOS to its default values, that might solve the problem.

And your Windows 10 was booting in UEFI with Secure Boot enabled, I suppose?

And which Linux distribution exactly are you trying?

My PC is an Acer Aspire V5-531P that my father bought me. The problem is that when I press F2, I hear a beep but nothing happens and the PC boots. I can't reset my BIOS or update it because I can't access it, and the operations need to be done under Windows.
My W10 was indeed booting in UEFI/Secure Boot.
And I am testing Ubuntu 16.04 in Live.
