how to disable display driver signature enforcement in Windows 8 Developer Preview with developer tools (x64).

    Question

  • I tried to install a unsigned display driver in Windows 8 Developer Preview with developer tools (x64) but failed. I couldn't find boot menu. After running cmd below, i can see legacy boot menu, but no option there to disable signature enforcement. Thanks for any help.

    run bcdedit /set {guid of my bootmgr} displaybootmenu yes
