5 rEFIt causes kernel panic. Please help. - ID: 2859681

Last Update: Comment added ( chrisp )

Details:

Yesterday, I ran software update on my Mac Pro (early 2008). I had rEFIt
installed before the update, and when the puter restarted, I had a kernel
panic during boot. rEFIt is the first thing to load. If I select my Vista
drive, it loads and runs just fine, but the OS X partition is FUBAR. Right
now I have been trying to uninstall the rEFIt software, as per the
instructions on the rEFIt site, but since I can not even load OS X, I can't
select OS X as my start up drive.

I tried using the Firmware Restoration CD 1.5, but rEFIt takes over before
it can load. The OS X installation disk also experiences kernel panic.

I really need to find a way to remove rEFIt from my EFI. I went to the
apple store, and they told me that since I used rEFit, I voided my
warranty. The geniuses told me that rEFIt more than likely killed my EFI,
and I would need a new logic board. (Logic boards cost 800 bucks)

Any wisdom?

Date: 2009-09-28 16:12 Sender: chrisp It's scary to hear how a supposedly well-educated Apple Genius will claim that rEFIt "killed EFI". At boot time the only thing rEFIt writes to is the MBR sector of the hard disk, and at Mac OS X runtime it uses command-line tools written by Apple and shipped with Mac OS X to change the boot volume / boot loader. I don't see how any of this could affect your machine to the point where Mac OS X won't even boot from the install CD. I'd recommend to try a SMC reset (http://support.apple.com/kb/HT1806 for the Mac Pro). I've had an issue with my Mac mini where even the install CD wouldn't boot after running Linux, and the SMC reset got the machine back to life.

Have your OS X dvd in the drive first and select it to boot from it. Use the Terminal (under the Utilities menu) to re-bless your Mac OS X partition. Simple. NOW when you reboot, no rEFIt menu will be shown. Just normal Mac OS X startup. Replace motherboard. Ha! :-( need more detailed help? Then post again friend.
