The USB will boot when UEFI is disabled and changed to Legacy BIOS but it will not let me install. Also in step 11 it mentions the file "sources\install.wim\1\Windows\Boot\EFI\bootmgfw.egi". However I cannot find any file as such - just bootmgfw.efi not .eg​i Is this a typo or not??
    Hello jamerst, and welcome to Eight Forums.

    Yes, it's bootmgfw.efi and not egi.

    Double check to make sure that you do not have "secure boot" and "fast boot" enabled in your UEFI settings.

    I'm just going to bypass the UEFI installation completely, found a post on how to do it. I'm not that bothered about having UEFI and it's just being too much trouble so thanks anyway.

    Are you using a USB 3.0 port?

    No as far as I know as the computer came with very little documentation, but anyway I'm just going to bypass it.

    Hi everyone,

    (And sorry for bad english)

    I've got exactly the same trouble : error 0xc000000d (BCD) when i try to install Windows 7 Pro x64 with USB Flash in UEFI mode on ASUS UX31A (with Windows 8 Pro)

    I have carefully follow the tutorial and all i have found on the net : disable secure boot, CMS, enable USB Legacy ...

    I have only USB3 Ports (my Flash drive is USB2) but i have turn on USB legacy in "Bios".

    I have tried to change the Letter in BCD with Visual BCD Editor but nothing, always the same error.

    Perhaps the only way is to buy an External DVD for installation ?

    Best regards,

    Kiss.

    I don't care of UEFI.

    I read the tuto but im not sure its possible to turn on "Legacy Bios"

    In the bios, it's possible to delete the boot option : Windows Boot Manager , but perhaps its risky ^^ ?

    Or Add New boot option : i can choose a path for boot option.

    Kiss

    Legacy BIOS should be in there somewhere. You have to switch the mode from UEFI in the same selection thing (as in not a separate option if you know what I mean) Mine looks like this and you simply press F6 to toggle the mode. Click image for larger version
