How to disable Driver signing in Windows 7?
This works without having to press F8 on bootup to disable driver signing.
Go to the Start menu and type cmd.exe in the Search Bar. Right click on cmd.exe and choose Run as Administrator.
If you have the UAC turned on, choose Yes to proceed. Otherwise, you should see the command windows opened already. In the shell window, copy paste the following and hit Enter.
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON
After you reboot you will get a see a new stamp in the bottom right of the screen "Test Mode, Windows 7, Build 7600"
Now all of the unsigned drivers you have for x64 will work and load fine.
