Yes, i didnt knew that one..microsft lunchs a few options in OS that are not compatible with the OS... LOL looks like the one...no keyboard detected please press F1...LOL
Well i found something else that could help you:
Go to Start menu and type cmd.exe in the Search Bar and press Enter. (Remember you must be logged on as Administrator)
Now type the following:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
hit enter
bcdedit.exe -set TESTSIGNING ON
hit enter
Restart your computer
If this is inaccessible then change it via Registry:
1. Go to Start -> Run -> regedit.exe
2. Look for: [HKEY_CURRENT_USER\Software\Policies\Microsoft\Wind ows NT\Driver Signing]
3. Change the BehaviorOnFailedVerify key value to "0" for ignore, "1" for getting just warning mesage and "2" to block completely.
See if works
