Failed to mount Bios on /mnt/mmc with 32gb sb

the error just means that it cannot access the folder /mnt/mmc/MUOS/bios on the SD card.

  • Could be a bad image download (verify the hash)
  • something went wrong flashing (try using Raspberry Pi Imager to flash)
  • bad sd card (run through this article to validate condition of your sd card microSD Card Health)
  • the folder was deleted (pop it into a sd card reader and try reading and writing to the MUOS/bios folder
