Hi,

First I've already read the thread on the Boot error Gpt and tried to apply the terminal command line after unmounting OSX disk..."No such file or directory."

I had a smooth ML os running from 4 months and all of a sudden nothing worked, even the windows partitions...Seems like a hardware problem.

I managed to get back my drives after a clear CMOS...

Diskutiliy detected the OSx disk to be corrupted, so i formated and reinstalled osx ML.

Now i have the Boot 0 error GPT screen.
It can only boot with the usb flashdisk (but with no audio and ethernet). I installed the Chimera standalone successfully :/

Where did it go wrong ?

Thx !

SOLVED!!!

Copy booth1h file to USB root

Run the installer using the flashdrive USB then Unmount OSX disk using Disk utility
Then open terminal

change directory to USB
command line: cd /Volumes/USB(or whatever name of the flashDrive)

then

dd if=boot1h of=/dev/disk0s2

This will change the size format of the disk allowing you to boot on OSX.
