I have resized my bootcamp partition because I needed more space. I used GParted live for it.

 

Now after I resized it I can not boot it anymore, but it can still be found in the finder and it can be selectet in the startvolume.

 

If it is selected in startvolume it gives an error, after booting and the win cd for repair also doesn't work.

 

I also tried to fix it with rEEIt but also not working.

 

for further infos aboute the disk:

 

 

markus:~ markus$ sudo gpt -r -vv show disk0

   4:       Microsoft Basic Data                         139.2 GB   disk0s4

 

 

my guess whats wrong is that  4 is not recognized as bootcamp partiton and is not able to boot because of that. But I have no clue how to fix it.

 

Thanks for help beforehand.

    You cannot resize a Boot Camp partition that way. Now you will have to try removing the entire partition, if possible, using Disk Utility, and extend your OS X partition to the full disk size. If you are lucky this may work. But more likely it will not. In that case your only recourse is to repartition the entire drive back to one volume and start over. Since this will erase everything on the drive you should backup your OS X volume.

     

    BTW, rEFIt does not work with Mountain Lion. Instead, use Boot Runner.

    You have damaged your partitioning tree and have removed a small but very important hidden partition of about 200mb which is the Bootcamp/WINDOWS boot Rom.

     

    Table should be

    1.   EFI 200mb

    2.   OSx

    3.   Recovery. 650mb

    4.   Boot camp/Windows Boot Rom 200mb

    5.   Windows

     

    You will now have to reformat the whole drive and reinstall .

     

    When you use Bootcamp only use the Bootcamp utility for formatting the Windows Partition as this adds that hidden Boot Rom partition.
