My Laptop do not boot in Clover UEFI
I have a Dell Notebook Latitude E6420 (i5-2540M @2.60GHz, 4GB RAM, 350GB HardDisk) and I m running Niresh Os X Yosemite in Legacy Mode with great success! I want to upgrade in Sierra and I downloaded Sierra Zone and I have made a Bootable USB according to instructions! I tried to install (clean install in UEFI Mode) but all I get after 15 minutes is a black screen with nothing! Clover default boots (as I already saw) are : -v darkwake=0 dart=0 slide=0! So even though clover has the -v flag does not shows any signs in the screen so I know when is the problem! I tried to add the -x flag but again does NOT shows anything or moves a thing!
What are your suggestions?
Thank you very much!
