#206 Mac Unable to Boot after rEFIt Installation

Derrick Lee

I followed the instruction here,
I did a Automatic Installation with the Installer Package.

After restarting two times, the menu isn't up yet.
My Mac won't boot up, It just loads a circle with a slash across forever.

Command + S keeps telling me "Searching for root device", or something along that line.

When I tried to boot from my Installation disc while holding down C.
I went into Disk Utility and my Mac HD was renamed to disk0s2.

I am unable to mount that disk, reinstall mac os, repair the disk or anything else.
My Mac is completely dead now.

I am unable to go into safe mode.
I am VERY sure this happened immediately after I installed rEFIt.

    Connect your Mac to another using a FireWire cable and use Fire Wire target disk mode to try diagnosing the problem of your Mac's hard disk there.

    Use the script at to list your partition info.

    Compare the GPT and MBR with what you expect to be there.

    The same thing happened to me too. Fuck, my Mac is a complete brick now! Btw, I can't wire it up to another Mac because I only have one.

    oh, there's one difference though: I can't even boot from the OS X installation disc. Gets the same result: A circle with a slash

    Puhh, I fixed it again. Here's what I did:

    From the rEFIt menu, I chose to rewrite the MBR. After that I was able to boot from a CD again, but not from the hard disk. I then booted from the Mac OS installation disk and started Disk Utility.

    In Disk Utility I selected Repair Disk Permissions, and then Repari Disk. After that, Mac OS was booting again.
