10.8.3 can no longer boot

I'm running on a GA-Z77-DS3H v.1.0. I installed via the combo update, then ran MultiBeast before restarting. For the record, I FORGOT to repair permissions. Now the system will not boot, and I can't seem to get it to boot from my CarbonCopy drive either. Interestingly, my custom Chimera icon is also now gone.

If I boot with verbose, I see this:

Read HFS+ file: [hd(0,2)/System/Library/CoreServices/SystemVersion.plist] 478 bytes.
Loading Darwin 10.8
Loading kernel mach_kernel
Read HFS+ file: [hd(0,2)/mach_kernel] 4096 bytes
Read HFS+ file: [hd(0,2)/mach_kernel] 8187856 bytes

And that's it.

GA-Z77-DS3H, i7 3770, HD Radeon 6870, 128 SSD for boot. Any ideas? Anyone have this board and know how I can at least boot from CarbonCopy?

I got almost the same spec with you.
GA-Z77P-D3, i7 3770, HD Radeon 6870, samsung 830 256GB. Stuck at Apple logo.
I did repair permissions before restart. I also did make a carbon copy before upgrade. But My backup can boot to 10.8.2

Now, I just manage to boot up. What I did was disable vt-d in the BIOS. You can give it a try.

Thanks for the advice! I checked mine and it was disabled. I gave it a shot with 'enabled' just to check. I think it has to be something with Chimera. The logo has changed for no reason.

I have the same situation here. It seems I am back to the old chimera instead of chimera 2.0.1 which I installed some days ago. Any ideas?

I'm having the same issue. Thought it was my graphics card, but I have the same message when I booted in verbose. Any ideas on how to fix yet?

No it is not the graphics card since I don't have any dedicated card but are using the HD4000.

I was able to boot into Windows and am currently copying all my files over to a backup drive. May just bite the bullet and buy a MacBook Air! Any luck on rebooting into Mountain Lion?

I have the same board and problem..

I tried to boot with unibeast stick but without luck..


Rick,

I have yet to find a solution, although booting with the Unibeast stick seems to be working.

Had the same issue with my Mac-mini Hackintosh..GA-H77N-WiFi, Intel Core i3-3225 (using HD4000 graphics), etc.

...rebooted -> F12 -> from the Unibeast ML USB-HDD -> select system ML using -x (safe mode) ->now reboots in Safe Mode...

...move to Trash from System/Library/Extensions both AppleHDA.kext and HDAenabler.kext. Also moved /Extras/ folder to Trash...

...full reinstall Multibeast 5.2.1 with all my previous settings (as per TonyMac guide)...shut down...

...again, reboot -> F12 -> this time, boot into Unibeast ML on USB-HDD -> Repair Permissions on system disc...

...now, reboot normally.

This worked for me...everything seems to be functioning OK, so far. (Also, reinstalled MacMan's Chimera 2.0.1 just to be on safe side.)

Good Luck!
