Hi, Iost a partition for Windows. This is how it happened:

Question

First, I installed windows 7 using bootcamp. I put in 150Gb for windows and 350 for osx. Everything went fine. A few weeks later, i decided to get windows 8. I got the files into a flash drive using bootcamp and when i had to put it in a partition, i chose the windows 7 partition and formatted it. When i clicked ok, it told me windows cannot be installed in this disk. I went back to osx and decided to delete that partition and put in a new one using bootcamp. When i clicked restore, it said the disk cannot be restored. I researched a little bit and decided to format the partition with disk utility. After i did that, the partition for osx was still at 350gb and the win7 partition was gone. I booted to my win8 installation flash drive and at the point where i had to chose a partition, the win7 partition read 'unallocated'. I hope u guys can help me with this. Thanks

Hi all,
First, sorry to interfer, but I have a similar problem.
@Christopher Murphy:
I saw your answer on this thread (https://discussions.apple.com/thread/4144252) and was trying to find a way to contact you, because I have a similar problem.
I used Paragon Camptune X to expand my bootcamp partition. But now it is not bootable anymore...
I am on a Macbook Pro 13 mid 2012 with Mavericks, I installed gdisk and ran those commands :
sudo gpt -r -vv show disk0 :

I hope I don't ask too much, but if you would help me it will be very useful.
Thanks in advance,
