windows - Can't access bios after legacy boot


What happened is this:
Basically, I was running Windows 10 on Acer Predator G9-791 and I sort of played around in BIOS.


When I have changed the boot mode from UEFI to Legacy and restarted the laptop, I could only see a somewhat smaller logo on boot that says "(Acer Predator image) Predator", but nothing happens after that.


That would not be a problem if I could just switch the boot mode back to UEFI, the problem is, that after this change to Legacy I can no longer access BIOS with F2, I tried using different keys (del, esc, f1-12) but that didn't work either, please help, what should I do?


EDIT:
When I removed SSD with windows, it booted to some sort of terminal or something and it keeps saying:



Intel UNDI, PXE-2.0 (build 083) Copyright (C) 1997-2000 Intel
Corporation.


For Qualcomm Athernos PCIE Ethernet Controller v2.1.1.5(03/15/13).


Check the connection! PXE-M0F: Exiting PXE ROM. No bootable


device -- insert boot disk and press any key





TL;DR: I can't access BIOS anymore after setting my boot system to legacy


Answer



This is how I have managed to solve this:



  • Remove the SSD/HDD that contains Windows10 boot (or any other boot drive)

  • Start the PC and instantly spam F2 key (or whatever is the key to access your BIOS)

  • You should now be able to see BIOS.

  • In BIOS, Change the boot system back to UEFI (in case the option is no longer there, restore the factory settings of BIOS)

  • Shut down PC

  • Connect the boot drive

  • The PC should now be booted into Windows (or any other OS)


Although, I still do not really know, why I wasn't able to access the BIOS instantly without removing the SSD, but this solution has worked for me
