I know there is plenty of threads about Windows multiboot but I haven't got my problem fixed. I have install Windows 7 and XP earlier and I used EasyBCD to make multiboot work.
Now I need to install Windows 8 and encountered some problems. When I installed Win8 the first time everything went fine. After first reboot Win 8 started and I was able choose if Win 8 would be the main OS. I choose Win 7 instead. After that I added a new entry for Win 8 in Win 7 and EasyBCD. For the entry I chose the driver where Win 8 is installed.
Now I can see the Win 8 in multiboot menu but when I choose it there is a error message shown something like: "Windows cannot verify the digital signature for this file.' - \Windows\system32\winload.exe "
If I reinstall Win 8 it wont go on that graphical Win 8 multiboot menu anymore (it did first time). Is there some steps after the first reboot that should be done? After first reboot it will only show the multiboot menu of Win 7 and the installation of Win 8 wont continue.
