Hello, I get this message "Reboot and Select proper Boot Device" when I turn on my PC. I tried to look for videos to solve my problem, but nothing seems to fit.

I initially had a bluescreen saying "A problem has been detected and Windows has been shut down to prevent damage to your computer..."

I was using F8 "Advanced Startup Options" to access Safe Mode, but now it no longer works (probably due to an incorrect handling).

In "ASRock Instant Flash," I see "No BIOS file found," so I used a USB drive to flash a new one, but the problem has not been resolved.

I don't know what else to say or do... Thank you in advance for your replies.

      Try putting "hard disk drives" first with the F5 and F6 keys.

      You should go to the Microsoft website, download their "Media Creation Tool", then download the ISO file of your version of Windows (10?), then mount it on a USB stick of at least 8 GB, in MBR mode since we can't tell if the BIOS is in UEFI. Then insert this USB stick on startup of the PC, go into the BIOS boot settings to set it to boot first and install Windows without losing data first, especially if you haven't backed up your personal data. If it fails, try with data loss, good luck!

      Hello,

      The situation, as evidenced by the CMOS Checksum Bad error, seems more likely related either to the CMOS battery itself, which should be considered for replacement if the PC is very old, or to the BIOS itself (possibly another hardware issue, RAM, motherboard, but unless there's a failure, we'd remember hardware changes, lightning short circuits, sudden shutdowns, or bumps and falls...).

      It seems normal that there's nothing in the Instant Flash section if we haven't loaded an appropriate firmware onto a bootable medium (USB stick), but it appears that this BIOS has already been flashed, perhaps inappropriately (in which case you need to find the original version to download from the manufacturer and attempt the reverse operation).

      In any case, this does not indicate a Windows error, and reinstalling Windows 7, 10, or whatever we want will likely not solve the issue.

      Firstly, there is probably nothing to purchase (except possibly a battery) and nothing else of priority than to ensure that the Bios version is correct.

      The first operation is not very complicated; it is usually an ordinary CR032 battery. The second one is more complex; you need to be sure to find the correct Bios version and be able to restart from a USB drive containing it, with no guarantee of success. If necessary, it can be entrusted to a hardware geek in your circle if you have someone you can trust; otherwise, to a repair technician, but you should request a quote first.
