    Firmware update nightmare.

    Reboot and Select proper Boot device

    Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key

No bootable device -- insert boot disk and press any key

    I was updating the desktop's BIOS using the X48TurboTwins-WiFi Bios package from ASRock. Then it rebooted twice. Since then, black screen. I'm reasonably technical but I've never had to recover a BIOS. Is this repairable at home? The keyboard lights flash briefly when I press power, then nothing. I have another computer available to download files and prepare a USB stick if a recovery procedure needs it. I just don't want to make things worse by guessing.

    thinking

    been there man clear CMOS (jumper or removing teh coin battery for a few minutes with power disconnected). A failed update sometimes leaves settings that prevent POST, not a corrupted BIOS. lmk how it goes

    reading release notes like its a horror novel

    First, wait. Some firmware updtaes continue after a reboot with a black screen and fans at full speed. Leave it on, plugged in, for at least 15 to 20 minutes before concluding it failed.

    nothing is more permanent than a temporary workaround

    lol

    hmmm many laptops have a BIOS recovery mode: often holding a key combination (like Ctrl+Esc or Win+B) while connecting the charger, sometimes with a recovery file on a USB stick. check your PC makers support page for teh exact procedure for your model.

    windows update said 'this will only take a moment' 3 hours ago

    Many desktop motherboards have BIOS Flashback/Q-Flash Plus or a dual BIOS. These let you flash from a USB stick without a CPU or a working BIOS. Check the motherboard manual for the exact file name and port.
