Bios wont boot on Aspire 515-54 Model N18Q13

When I turn on the laptop and hit f2, bios doesn't load. Instead I just get a black screen with a cursor/underscore on the top left but it won't open. How can I reset my bios via windows 11, as that's the only thing that will boot. USB drives won't read through f12 either, just windows boot options. Thanks

    I’ve tried every version of getting into bios I could, they all resort to restarting in UEFI bios which goes back to the blank screen with cursor. I did get into a safe mode troubleshoot option and selected restart via USB but when it restarts it says that the boot loader doesn’t have an option for USB and reverts back to the windows boot line item. Is there no way to do a hard reset on bios that doesn’t involve restarting into bios? Acer must have a way to reset its bios settings?

    All standard restarts into bios tricks didn’t work.

    Got into defaulted bios by removing the bios battery and holding another little button on the MB down.

    New issue, I can only boot to windows and windows is going blue screen on me of inaccessible boot device. It restarts into automatic repair but hangs there and does nothing.

    Bios will not let me include USB as a default boot option either. Even if I enable fast boot in bios, it still doesn’t show up on the list.

    Any other idea to boot from USB?

    I have the very same laptop (end 2019, Windows10 Home) and got the same problem after tweaking the system trying boot faster: I changed SATA mode from RST with Optane to AHCI in UEFI and that corrupted the boot sector on my (spinning) HDD. Ended up sending the laptop to Acer Services (I first copied my files to another PC and reformatted the HDD for privacy): Acer factory installed the system for free (my warranty expired already) and I had it back in 2 weeks (live in the country). Up and running ever since, after 4 years on W11 22H2, never crashed, system never hangs, do have some Power Button issues recently (occasionally won't start) but OK again after resetting my battery. AOMEI published a good article how to rebuild the boot sector, never tried this, but others on this forum repaired successfully the bootloader on SSDs and spinners. That Blue Screen you are seeing is WindowsRE (recovery) either on your USB or on the recovery volume of your HDD.
