If the EFI boot order keeps resetting after a reboot, it could be caused by several factors. Here are some steps to troubleshoot and resolve the issue:

  1. Check for Firmware Updates: Make sure that your motherboard's firmware (BIOS/UEFI) is up to date. Sometimes, motherboard manufacturers release updates that address boot order and other issues.

  2. Reset BIOS/UEFI Settings: In some cases, the boot order may be reset due to incorrect BIOS/UEFI settings. Try resetting the BIOS/UEFI to its default settings and see if the boot order is retained after a reboot.

  3. Replace CMOS Battery: If the computer's CMOS battery is weak or dead, it may cause the BIOS/UEFI settings to reset after a reboot. Try replacing the CMOS battery with a new one.

  4. Check for Malware: It is possible that malware or a virus could be causing changes to your system settings. Run a thorough antivirus scan to check for any potential threats.

  5. Boot from Correct Device: Ensure that you are booting from the correct EFI boot entry. Sometimes, multiple boot entries may point to the same operating system, causing confusion.

  6. Manually Set Boot Order: Try manually setting the boot order in the BIOS/UEFI settings and save the changes. Check if the boot order is still reset after a reboot.

  7. Check Boot Manager: If you have multiple boot managers (e.g., Windows Boot Manager and GRUB), make sure they are configured correctly and not conflicting with each other.

  8. Use Boot Repair Tools: There are some boot repair tools available that can help diagnose and fix boot-related issues. For example, on Linux systems, you can use the "boot-repair" tool to repair EFI boot issues.

  9. Check for Hardware Issues: There may be hardware issues with the motherboard or the storage devices that are causing the boot order to reset. Check for any hardware-related errors in the system logs.

If none of the above steps resolve the issue, it is recommended to seek help from the manufacturer's support or an experienced technician who can further diagnose and troubleshoot the problem.
