I have an HP PC at work. In it's boot options I set USB as the first option for the UEFI boot order. Then SATA Optical drive. Then m.2.
I boot off the USB with macrium reflect on it. Works fine.
I restore an image onto the m.2 drive. It is a Windows 10 image, using UEFI boot (converted from legacy bios if that matters)
Then I remove the macrium USB and boot Windows from the new image.
Finally I insert the reflect USB again. Since I didn't change anything in bios, I expect USB to be the first item.
It reboots into Windows instead of reflect. I hop in bios and find that the UEFI boot order is changed, m.2 Windows Boot Manager is now the first item.
I do not understand how Windows or macrium can change the boot order. In my mind neither should have any ability to change this. All I can think is once the USB is removed the boot order is reset but even the optical drive moved in the list.
I do not have this problem with legacy bios boot order.
