People are confusing EFI boot with Secure boot.  You should be able to 
disable secure boot with no ill effects to Windows.  However, if you 
disable EFI boot (or change EFI Boot to Legacy, or CMS, or however else 
your particular BIOS wants to call it.) then windows will have to be 
repaired somehow.

Note that I've had at least one BIOS that would not allow disabling 
Secure Boot while EFI boot was enabled, and needed to be changed to 
Legacy Boot.  (I've later since  hints that it might have been possible 
to disable Secure boot if I first created a BIOS password.  I can not 
confirm this.)
