    Windows 8.1 Clean Install Reboot and missing Bootmgr.


    I am trying to install Windows 8.1 onto a new PC a clean install. I boot from UEFI CD/DVD Drive with the windows 8.1 install disk in it and it gets to the "Press any key to continue" screen, I press a key and it just restarts my computer. Then I try to boot from just regular CD/DVD Drive it says Missing BootMGR.

    I can provide you with any information about my computer that you need to help me. I just really need my computer running again and any help is greatly appreciated.

    I've zero experience of UEFI but it would help others looking at this if you posted your make and model of PC.
    I turned this up,

    Clean installing from a regular drive shouldn't be an issue as long as the BIOS is set to boot from the drive.

    The UEFI part throws me because I have zero experience of that... I would need it all in front of me to see what was happening.

    You may need to format the drive. Also, this may be of help: Boot to UEFI Mode or Legacy BIOS mode

    Could you clarify what kind of install disc you are using? One created from ISO?

    OK, a bit confused here. Normally, to boot from the DVD you have to hit any key a few seconds after it starts to boot or else it tries to boot from the hard drive and you will get an error.

    It is either that or you do not have your BIOS set properly to boot from the DVD drive.
