Will try that. Just need to sort out some downtime for the machine. I had been working on this a while ago. Got to this point BootOrder: 0001,0000,0002 Boot0000 Unraid Internal Boot (sdf's ESP) Boot0001 Unraid Internal Boot (Mirror) (sdg's ESP) Boot0002 Unraid Flash (USB) After a reboot this was the outcome root@NASEAA363:~# df -h /boot Filesystem Size Used Avail Use% Mounted on /dev/sdi1 30G 2.4G 27G 8% /boot efibootmgr -v BootCurrent: 0002 Timeout: 0 seconds BootOrder: 0002 Boot0002* Unraid Flash HD(1,MBR,0xc3c1e756,0x800,0x3a97800)/File(\EFI\BOOT\BOOTX64.EFI) dp: 04 01 2a 00 01 00 00 00 00 08 00 00 00 00 00 00 00 78 a9 03 00 00 00 00 56 e7 c1 c3 00 00 00 00 00 00 00 00 00 00 00 00 01 01 / 04 04 30 00 5c 00 45 00 46 00 49 00 5c 00 42 00 4f 00 4f 00 54 00 5c 00 42 00 4f 00 4f 00 54 00 58 00 36 00 34 00 2e 00 45 00 46 00 49 00 00 00 / 7f ff 04 00 Then this the entries were just deleted. It seems the motherboard is rebuilding the boot entry. At the end of the dat to server still boots. This is a nice to have option

unfortunately only showing unraid flash in the boot options within the bios

MSI PRO B760M-P firmware 7E02vAE Release Date 2026-04-09 does not retain or recognize custom EFI boot entries pointing at the pool — wipes them on every POST. Any help or advice would be very welcome
