    Have you tried to boot into your USB/DVD with Windows 8 and try to repair it from there?

    Thank you, netbox! I tryed that and I succeded with these commands:
    bootrec /fixboot
    bootrec /fixmbr
    bootrec /rebuildbcd
    Then it ask if I want to add the new entry, of course, yes! But I think was enough if I'd type simply:
    bcdboot.exe X:\Windows , where "X" is Windows 8 partition. I'm not sure of that, but I assume it works! Once again, thank you!

    Hi there
    I'd do it this way -- round about but works ( For MBR type Disks). This also has the advantage in that it gets rid of the BCD bootmanager too as well as freeing up the W7 partition.

    I'm not a big fan of "specialized" boot systems on Windows --fine on Linux where they belong.

    First prep work -- have these tools to hand

    Bootable program to restore an image
    Bootable W8 install media - preferably on a USB device.
    Bootable version of a partition mamanger say GPARTED - freely available on the net.

    Now :

    1) image your W8 system.
    2) download some type of bootable partition manager (I use GPARTED) but take your choice. Make it bootable from a USB if you can otherwise burn to DVD.
    3) wipe the W7/W8 partitions (with the partition manager downloaded)
    4) create ONE PRIMARY partition say of 75 GB should be more than enough for your W8 system) and set it to ACTIVE.
    5) restore your image to the partition you created.
    6) Boot -- it WILL EITHER BSOD or report a message lke ntldr / Boot manager missing - no problem -- we would expect one of these outcomes.
    7) Now the trick is to boot your W8 install media and chose the Recovery (Repair your Windows system).
    8) it should repair the boot mgr - you might have to do the repair two times but should work.

    9) enjoy your W8 system and use the spare space for anything else -- enlarge existing data partition or whatever.

    I know your method got your system working - but in any case going through the steps I've outlined here is good practice when you really do have to try and re-create the system again.
