I've also experienced this. If windows wasn't shut down properly and the NTFS journal is incomplete, gparted will (understandably) refuse to resize it. This therefore affects both the live cd installer and the alternative installer.
I had to run gparted by hand to find the error buried in a sub-sub-subs- sub-menu. After that I just needed to boot windows and shut it down cleanly to get everything to work. But finding the error was not trivial. ** Also affects: debian-installer (upstream) Importance: Undecided Status: Unconfirmed -- [Feisty] uninformative error when resizing ntfs partitions https://bugs.launchpad.net/bugs/88095 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
