  1. Boot manager missing


    I have two identical Dell Precision 3430 desktop units with a 500GB RAID 1 array and Windows 10 on them. I set one up and created an image of it to load onto the other with a third party imaging program, Acronis True Image. In the Acronis software the image restored successfully but when I reboot the machine it says there is no boot device and now in the UEFI settings under the "boot sequence" tab there is nothing. On the other unit that I made the image from there is one option, "Windows boot manager", that is checked. I suspect that this is my problem. How can I get the boot manager back, or lacking that, manually set the hard drive with the fresh image on it as the boot device? I have tested the image on another machine and confirmed that it works.

    :)

    Boot Manager Is Missing

    You need to use the Bootrec.exe tool in the Windows Recovery Environment. For that you need to boot into Recovery Environment and perform a "Startup Repair". If that fails then boot into WinRE again, and go to the "Command Prompt" and execute this command:

    Bootrec.exe /RebuildBcd
