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!!
Excellent work, JC K9. Very happy to see it all work together. 😎
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
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...
And it's not possible to mount disk5
Can you start a new thread and post this information on the new thread? Please post a reference to the new thread on this thread.
Was you installation an EFI-based install, even though you have a Hybrid MBR as well? I am surprised at GPT#4 and GPT#5 that you have.
Sure, i do it right away
Thank you.
