[QUOTE="SpawnHappyJake, post: 1256980, member: 205651"] [b]Let me explain[/b] You always need a bootloader to load an operating system. There are bootloaders for BIOS and bootloaders for EFI. They are looked for differently. Mac uses EFI, though it does have a BIOS compatibility module that can make the EFI look and act like a BIOS. What triggers the Mac to list a drive with a BIOS bootloader as an option (to then boot through the compatibility layer), I don't know. But I can send you down the path of understanding: [url=http://pastebin.com/D8YdUEbc]Bootable Thumb Drive on Mac - Pastebin.com[/url] As far as root=/dev/[whatever], that's setting the root directory. You're making that be where the bootloader is looking. You are picking a partition to be pointed at.
