I can confirm this. I have formatted a winxp partition using fat32 in the windows install, and then, when I install Ubuntu, I get the same error.
I didn't stop, just installed Ubuntu. Then I got an error inode not in group. I ran e2fsck, answered yes to a couple of questions, and everything was fine. -- Problem while partitioning https://launchpad.net/bugs/58217 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
