I had Manjaro running hours ago, then a faulty USB flash drive led me to assume my very crappy BIOS could benefit from an update. Now the machine won’t boot from anything other than a Manjaro LiveUSB stick, because the only method that will boot is EFI. I can get an EFI shell or Manjaro will boot via EFI, but no other way will work. I cannot even access my BIOS to reflash. It’s either black screen and not even a POST, EFI shell, or Manjaro Live install environment.
Can anyone help? I have Googled for hours now, and nothing works. There is no flash.nsh or flash_me.nsh script for my mobo.
Ideally, I would like to somehow use Manjaro’s EFI boot ability to boot into FreeDOS to flash the BIOS and get back to normal boot functions. Is this possible somehow? Or I could use FlashROM from the Manjaro LiveUSB? I’m lost. I appreciate any help.
