Chameleon is the latest one 2377 and I tried GraphicsEnabler=No. I've just made a test on another Hackintosh with a myHack 3.3.1 fresh install (no MBR patch and no customized Extra folder) and it gave me the exact same error so it's not related with D830 setup, the issue come from myHack install. With Pandora's box and the same Install Mavericks.app the process runs just fine and I can boot without problem straight to the install screen, but with myHack, no way.
BTW, I did a Dell Online Diagnostic with MyDell Tool and except for the battery and LCD screen issues, the re's no other identified problems.
