Boot Order keeps getting changed

[Car712]

Hey, so right now im having quite an issue with the boot order on my PC, I have 2 bootable Windows 10 installations, one on my NVME Drive which I actually use, and another on a small USB 3.1 Drive that is a "bait" Windows Install in the case that my PC gets stolen. I set the boot drive order to having the USB be in slot 1, and all the others disabled (to get into my NVME I would have to press F12 at startup, which a thief would theoretically have no idea about). Anyways, the USB boots fine with that boot order, as long as I dont boot into the NVME ever again, but once I rebooted my PC, went into the NVME, and then rebooted again, it went to the NVME straight away, and the boot order was completely changed, with the NVME being at slot 1, and the USB at slot 2!! This is very maddening to me as I have had nothing but trouble with this Gigabyte motherboard's awful software and BIOS since I got it... I really hope someone knows a solution for this to make the boot order permanent and to stop it from being changed. Please let me know!

I’ve had this problem on old PCs. This may not apply to win10, but when this happened to me it happened because there were multiple places to set boot order on multiple levels.  I would change the bios, but when I booted the higher level thing I didn’t change changed it back again.

It will be Windows EFI automatically prioritizing its Windows Boot Manager. 

Try disabling Fast Boot in your UEFI/BIOS, and see if that stops the behavior. 

 

If it's still happening, you should be able to use a utility like EasyUEFI or maybe EasyBCD to remove the 'Windows Boot Manager' entry.

Don't forget to create a UEFI backup before modifying it.
