boot0 error Mountain Lion GA-Z97X-UD7-TH

[jordan.king92]

I know there are a ton of boot0 error threads out there, but I have not found any that are for Mountain Lion on this board. I've read through all the boot0 error threads and still cannot find a fix that works for my rig. Currently the only way to boot into my OS is to boot from the Unibeast USB. After booting the computer works fine, but it can't boot on it's own.

I've tried the golden thread approach of using the dd= command to copy the boot1h file from the Unibeast USB, but that has not worked. I've also tried copying with the bs=4096.

I've installed and reinstalled the chameleon bootloaders using the chameleon wizard, and I've tried many different versions of chimera from the Multibeast 5.5.5 for Mountain Lion.

The boot drive is the recommended Samsung 840 EVO 250GB. I've read that the 4K sectors could be the issue, but I haven't been able to find a way around it.

I am currently running Mountain Lion 10.8.5

If anyone has any insight on how to fix this issue I would be extremely grateful!

Update the firmware for use in a Mac. http://www.samsung.com/global/business/semiconductor/minisite/SSD/global/html/support/downloads.html

scroll down to bottom of page. Make a bootable clone before updating as it may wipe your drive - early firmware update versions certainly did this.
