I am running a dual-boot system with Windows 7 and Ubuntu 10.10. Initially I allocated about 20GB for my Ubuntu partition; however, I quickly ran out of that space and am now looking to expand my partition. Currently my NTFS partition (450GB) has about 130GB of free space. I tried using GParted to shrink the partition but encountered the following error. I booted into windows so I could run chkdsk but the countdown freezes at 1 upon reboot. I tried multiple methods to resolve that issue but nothing seems to work. Finally I gave up, and now I just want to know what is the best way for me to force GParted to shrink the partition regardless of the errors. I don't really have anything important and I don't mind risking the data. I just don't want to wipe the entire NTFS partition because I don't have a Windows install CD and might require Windows later on for some programs. I tried using sudo ntfsresize but that spews out the same error as GParted... Any ideas?

NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE!
The usage of the /f parameter is very IMPORTANT! No modification was
and will be made to NTFS by this software until it gets repaired.

Try this application on Windows: http://partitionwizard.com/free-partition-manager.html
It can actually work with ext too.

As far as I know, the linux-based NTFS tools will refuse to touch a NTFS filesystem unless it is already perfectly consistent, so as to minimize the chance of data loss. Are you completely unable to boot into Windows?

If you really really don't mind losing the data, you can delete the NTFS partition completely, and grow your linux partition to take up the extra space. I recommend doing this from a Live CD.

I vaguely remember the NTFS mount program providing the option to mount a damaged filesystem as read-only so that you could recover data off of it, but I could be wrong.
