    The download returned the wrong hash sum. Will try from microsft again. But I must have downloaded maybe 10 iso files now, and while I have checked all of them, it is weired that not one would work.

    I mean, if I use the downloader program that microsft provides then it goes through some file checking, I even got a corrupted download message a couple of times, this is making me pretty furious... Why want it work???

    I now have a iso with correct hash sum. Tried to make an bootable usb with the windows tool, but when I tried to boot I got the same bootmgr image is corrupt.

    Anybody have any clever ideas to what I can do?

    Further development:

    I have now tried to boot from a dvd which is burned from a ISO with correct sha1 hash sum. This dvd booted fine in my girlfriends PC, but I'm not installing win8 there.

    But this same dvd does not boot on my computer, after choosing to boot from dvd I get the same error: bootmgr image is corrupt

    But as I write this, I'm restoring win7 through a win7 dvd burned on a identical dvd as my win8 dvd. And it booted with no problem.

    I am out of variables and I'm wondering if any of you have any clues to why I can't seem to boot from either a dvd, usb or sfter making an installation within win7?

    Please help me out here!

    Can I install just the win8 bootloader?

    Maybe if it is installed first then I can install win8 after that and be able to boot after installation?
