I have a big problem when i try to install Yosemite with several methods. First, i try the All-in-one vanilla Guide, and then the AIO Guide method but i have this error message when i try to boot my usb drive: "Memory allocation error! Addr: 0xdeadbeef, Size: 0x0, File: hfs.c, Line: 924. This is a non recoverable error! System is HALTED!!!". Next, i try the ##### method, but when the installer comes up with the apple logo and the little loading bar, it crashes and i have a black screen about 30%. I tries a many of boot flags but no success. Then, i try the [NEW]_USB Installer_OS X Yosemite Chameleon_r2570 v7 method, but the program won't start it says an AppleScript error. Then, i try THIS tutorial, and the boot loader doesn't come up, i just had a flashing cursor. Then i try the Clover Legacy method, it works like the Beast, when apple logo comes up, and loads 40%, my screen is gone black or restart the pc. Please, help me. I don't know what is the problem.
