Loner T you are amazing!! I got the system to boot on firewire and rebuilt the hybrid GPT. I am writing you from bootcamp partition and both systems are up and running.


Thank you SOOOOO much for all your help and patience with this. I truly appreciate all your help. It has been a great learning experience (not that I was expecting this). Your are amazing!!

Hello Loner T,


I try to post directly here, as my problem is quite similar.

But, yes theres is a "but" :-), i got a different display that seems more complex to me... i got 5 partitions and the one that seem to be the right partition is the 5th and the 4th dont remind me anything.


Here are my outputs :

I have run testdisk, could you help me on the output pls ?

That upgrade is going me crazy... :-D

Oct 27, 2014 2:22 PM in response to Loner T

Oops i forgot some details

At boot bootcamp never disappeared

Windows 8.1 bootmgr is launching but i think it's not on the right disk (disk 4 contain a strange temp folder and a recovery file) > seen on finder

disk4 has the ntfs header but it's not the right disk

disk5 dont have the same header

As i remember there are only 4 partitions on my computer...
