cannot enter BIOS on Samsung Notebook

[Cpt.Fox]

I'm trying format a notebook that was infected with malware and has network issues, the problem is that I can’t access the BIOS with an external keyboard (since the notebook keyboard is not working). I went to Recovery from Windows Settings, and I ran “Reset This PC” and it didn’t work, it reached 100% but then it undid all progress and it forced to restart.

Then I connected a bootable USB with W10 and went to Startup > restart now> Troubleshooting> Advanced Options > boot from USB, but it did nothing. I tried both UEFI bootable USB and using just the ISO file on the USB.

So I had no other option than formatting the disk using Diskpart and cleaning all partitions, hoping that this would make it possible to boot from the USB. However, when I tried to do this it wouldn’t let me boot into the BIOS and it reads the following: “All boot options are tried. Press F4 key to recover with factory image using Recovery or any other keys for next boot loop iteration”. I pressed F4 and nothing happened.

To sum up the external keyboard doesn’t seem to work and I can’t enter the BIOS, even when I tried using several F keys with 3 different keyboards. Do I need to buy a new notebook keyboard?

Yes, what's wrong with the built in one?

Nvmd, open the laptop and verify the keyboard cable is plugged in

Usb keyboard should work and laptop bios buton is F2, reset is F4 or Esc according to quick search, try different usb ports. You tried 3 keyboards so unless all are broken my guess is whatever you got infected with locked out the ports if all of them don't work with combination of F2 F4 and Esc or Delete.

Does laptop display anything?

yes it does , when i press the power button the Samsung logo appears for a few seconds then it shows a black screen with the following text : “All boot options are tried. Press F4 key to recover with factory image using Recovery or any other keys for next boot loop iteration”. However F4 doesn't do anything. Notebook owner told me that he spilled coffee on the notebook keyboard some time ago and it hasn't worked since so he just used an external keyboard. Im thinking that i should open up the bottom of the notebook to disconnect the internal keyboard cable, it might be already disconnected for all i know. This Notebook was already disassembled by someone else before and they clearly didn't do a good job at it, there are some small gaps on the side of frame so its not closing up properly and god knows what else they did wrong inside. Im afraid disassembling myself for i might no be able to reassemble and close it up again.

As a last resort id have to remove the HDD and install on another PC to install windows
