I've been trying to follow the instructions here to increase the size of my boot camp partition:

http://plonsdale.wordpress.com/2011/06/24/tech-tip-increasing-the-size-of-a-bootcamp-partition-with-free-tools/

I got as far as step 3 when I booted from the rEFIt CD. I selected the partitioning tool and it gave me the following message:

Error: Not Found returned from gptsync.efi

Now the Windows boot camp partition doesn't show up when I hold alt when starting my mac. Trying to boot into Windows using the rEFIt CD gives me a message saying no Windows installation is found. I then booted off the Windows 7 install CD and the 'repair' option gave me this message:

This version of System Recovery Options is not compatible with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of Windows

...and if I try and go install a fresh version of Windows on this partition using the 'Custom (advanced)' option I get an error about the partition saying:

Windows cannot be installed to this disk. The selected disk is of the GPT partition style
