Stuck in lock screen after installing Yosemite
2 2

Question

Hi,

I installed Yosemite Zone with an usb created by Transmac. The formating and installation went smoothly without signs of errors. After rebooting and selecting the new HDD installation, the Apple loading screen is replaced by a block icon and stays there forever.

This is right before the first time setup appears.

I tried with VGA and HDMI displays, and also booting with verbote and safe mode, the result is the same.

 

Your thoughts?

CPU: Intel Core i7-4790K 4.0GHz Quad-Core Processor
