Try a software called "Partition Magic", see if that help...
Do NOT use Partition Magic, there are serious issues.
THe favorite free prog seems to be Partitio Wizard, but it does not deal with Linux partitions.
Acronis Disk Director 10. a very ggod program, is supposed to br replaced with a Win 7 version nbext month.
I have ADD 10 in Vista and will be using it to create/resize partitions to install Win 7, and provide other partitions as well as reserve space for Ubuntu Linux.
Paragon Partition Manager 10 also looks good.
I have the Personal version, but have not yet fully tested the critter.
There's also a Pro version.
Alas, I also have Partition Magic. All I can say is #$#%^#%!!!!
I describe some of the issues in either the old Acronis Disk director forum at Wilders, and maybe alco in the new Acronis forum. But do not bother, it's not worth your time.
The knock on Acronis is their history of poor support and buggy releases.
A plus for Paragon is their very good support forum.
