Hi. I've prepared a pendrive to install Yosemite Zone following the two ways: by using TransMac on Windows and by using the restore pkg, on a VirtualBox Hackintosh with Mavericks. My Dell Vostro 5470 does not boot with the pendrive. I've tested on another laptop and the boot works. Someone can tell me what configurations I should make on my BIOS to boot work? Otherwise, there is anotherway to boot on my laptop? Thanks already.
