I bought a dedicated server and installed Windows 10(I have my reasons) on it with KVM.
The support staff has burned my .iso in a USB drive and I used to do the installation. But the problem is although I've installed the Windows on the server's HDD, it'll only boot to Windows if I select WIndows Boot Manager in Boot Override Menu.
HDD is my first priority in the list, but that way it gives me "No boot device blah blah found, please insert boot media".



Notice the entry in the second pic, choosing anything other than that won't boot into Windows.
