New to this website but pretty much here for the same reasons as everyone else. 
I want to turn my Dell Latitude E6420 into a Hackintosh but I am having issue installing OS X Yosemite from a bootable USB. 
I get stuck on a white screen and when I try to access the BIOS menu to unlock and enable legacy boot I am asked for an Administrative Password. Did anyone with a E6420 have this same issue as well? 
  
If so what did you have to do?
