I have the same issue, also installing alongside Windows 7. I did `ps axjf' and noticed it was stuck running `ntfsresize -f -i /dev/sda2', which was called by a partman script. I assume the script was trying to determine the minimum size of the Windows partition to give an option to resize it. The path to the script on the LiveCD was:
/lib/partman/automatically_partition/10resize_use_free/option My workaround was the remove the part of the partman script responsible for calling ntfsresize, since I already had my disks prepartitioned. Ubiquity worked fine after that, and it was able to automatically install alongside Windows 7. I'm probably going to post about this in the Ubiquity package bug tracker. ntfsresize is really slow on real world NTFS file systems and shouldn't be being used by Ubiquity in such a way unless requested by the user. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396380 Title: Installation stuck on "Preparing to install Ubuntu" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1396380/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
