Sudden boot0: GPT / boot0: test / boot0: done problem on previously working system

4 posts in this topic

Recommended Posts

Hello everybody, this morning when I rebooted my Hackintosh system I was greeted by the following lines instead of the usual Chameleon menu:

boot0: GPT
boot0: test
boot0: done

I was able to boot from an USB stick which had an OS X installer, and therefore Chameleon, on, but none of the common repairs helped. I tried to reinstall Chameleon, update to the latest SVN non-testing version, install Chameleon in another partition of the same disk on which i had installed Yosemite for testing (it didn't boot from there either), use the well known dd command (without the bs=4096 parameter) even if it doesn't look like the classic 4K sector issue (I do have a WD Caviar Black but as far as I know the 4K sector problem shows up with a "boot0: error" line).

I am attaching a DarwinDump hoping some of you will know where to look.

Thanks in advance.

Now quit the disk Utility and open the terminal Utility 
 
and type this 
 

dd if=/usr/standalone/i386/boot1h of=/dev/disk0s2

 
 quit the terminal and quit the Installation , reboot to your HDD    ;)

That would be the well known dd command I wrote about above...already tried, not working, sorry.
