I already thought that. Adding nomodeset doesn't help. Have tried it again. I must say that the computer boots the USB in EFI and I don't even know for sure if Windows is installed in EFI or in BIOS. Maybe it helps if i boot the USB in BIOS too? Or just try the 32-bit?
This really sucks. It used to be so damned easy to install ubuntu on your computer and now microsoft ruins it.
