So I have an issue that begins with the boot process, and I have no understanding of how to fix it when it breaks, for a lack of a better word. I know how to work and configure the BIOS, and I do know how to choose which UEFI to boot from etc. However there is some unknown corruption affecting my OS boot process. Ive even tried to download the update for my BIOS which includes an automatic BIOS flash and all of that; but when it tries and corrects the problem my laptop immediately restarts, and immediately reverts back to the broken, defunct, corrupted UEFI/ Boot , along with a stupid flashing underscore at the top left screen.
Any help from those knowledgable in these areas would be greatly appreciated.
