Repairing Bootcamp after creating a new partition

I made the similar mistake than in the similarly titled thread :Repairing Boot Camp after creating new partition


I created a new partition using disk utilities, rendering my bootcamp unbootable. I see Bootcamp in the boot menu in OS X. But when I try to reboot it fails.

Following guidelines from previous threads, here are my infos: (Build: OS X 10.8.5 (12F2560))

Please start a new thread and post a reference here and the output of the following commands.


1. diskutil list

caor-pcfixe-4183:~ Baltifru$ diskutil list

I'm vaguely familiar with the process considering the posts I read but not confident and skilled enough to do it by myself.

Could someone help me please ?

MacBook Pro, OS X Mountain Lion (10.8.5)

Hi,

thank you very much for everything, I am sorry for the late reply, but I've had surgery last week and was had unfortunately other problems to tackle.


for the moment my bootcamp is working properly, which was the main goal.

As you invoke doing a backup of my windows file, I assume I could lose them in the process. For the moment my windows install is really the priority so if it is the case I'd prefer to postpone that until I got my work prototype finalised.


Thank you very much again.
