  • Start by updating the firmware (UEFI). Commented Jul 1, 2022 at 11:41
  • @ChanganAuto How do I update the firmware? Commented Jul 1, 2022 at 12:54
  • UEFI is what replaced BIOS a decade ago. Likewise you go to the manufacturer's website to look for an update and instructions. This process is - should be - OS independent. Commented Jul 1, 2022 at 13:49
  • @ChanganAuto they are up-to-date Commented Jul 1, 2022 at 15:32

    does your system boot normally and otherwise work as you would expect? If it does, you can ignore "warnings" and "firmware bugs" errors that come up on boot. They are perfectly normal and don't affect anything unless you're doing kernel or driver development or something like that.
