Hi, I have this problem shown in the picture, when I start the system after the installation. I have try everything, but I can´t start the OS. I know that it works in my computer, because I has it running Mavericks before. I delete it by mistake during a Windows maintenance process. Now I'm trying to re install it in another drive. This are my PC especifications: ASUS P8P67-M PRO Intel Core i5 2500 ATI Radeon HD 5570 I don't know if you need more info about my sytem. Thanks for all.
