Hello. I posted a thread a week ago or so about my mac pro having problems with booting. Basically I never got it to boot to OS X as it gets a kernel panic whether I boot from Snow Leopard, Lion, Mountain Lion or Maverics, whether I use DVD, external drive, internal drive or even another mac via firewire. It boots windows perfectly though. Anyways, I am currently trying to install Ubuntu on it but as I read I need to boot into OS X and install rEFIt or rEFInd which is impossible. Is there any way to install a Linux bootloader without OS X or just install Ubuntu to a mac that's unable to boot OS X? I know it sounds weird but *sigh* this is my current situation.
