since my Computer decided to install Windows 10 i have been having a few issues Mainly, when the computer boots up, it asks me what Windows i wish to boot into, Windows 10, or Windows 7. if i click on Windows 10, the computer boots up as normal if i click on Windows 7 however ( the previous OS ) then it crashes, takes me back to the BIOS with the ''windows failed to start screen'' Windows only has the one operating system as far as i know ( was 7 but upgraded to 10 ) so im confused as to why its now reporting both basically i was looking for any way to disable the Windows 7 startup without having to go through a Reinstall of windows 10 ( that i have no boot media for ) as i am fed up with having to select windows 10 every single time i boot up
