I have a MacBook Pro with a working BOOTCAMP partition running Windows 8, and a damaged OS X 10.10 beta partition. The problem is that I cannot boot with the OS X partition, and in order to reinstall the OS I have to set a bootable media.
NB: I already tried to make a bootable usb using TransMac with the installESDInstallESD.dmg extracted from the installInstall OS X Marvericks.app but it doesn't work
Can I launch the installation directly from the Windows partition?
Is there any other way to make a bootable media?
