    I have found that was causes this issue after an update is that the BIOS loses its link to the boot image.

    I fixed it on my computer by removing "Windows Boot Manager" as an option in the BIOS and adding a new link to the harddrive and the image in the /boot directory. This will look a bit different depending on your computer but I hope this makes enough sense for you to find it on your computer.

    I fixed it by going into my bios and turning off secure boot. Go in to your bios go to boot find secure boot change os type to other os and unload the platform keys.

    Thanks, this also solved my problem.  Now is this a temporary thing that I can re-enable later or am I forever stuck leaving off secure boot now?  I take my PC security seriously and would like to be as secure as possible.

    Thanks,

    Hello :)

    I had a similar problem, what I did to fix it was:

    1. After pressing "ok to enter setup" go to Boot tab and where it says "Launch CSM" press enter and enable it.
    2. On the Security tab, select "Secure Boot Control" (it appears on the buttom) and disable it.

    Hope it helps

    I found this helpeful as well while converting a Windows 8 machine into an ESXi server for training; thanks.
