Public bug reported: gparted doesn't let you manage flags on a non-real partition (that hasn't been written to the disk yet), so it's impossible to create an HFS bootstrap partition using manual partitioning with the GTK frontend. The workaround is either to use automatic partitioning (and then overwrite everything but the HFS bootstrap partition using manual partitioning if desired) or to use the alternate install CD.
Sorry I didn't notice this until too close to release to fix it ... ** Affects: gparted (Ubuntu) Importance: High Assignee: Colin Watson Status: Confirmed -- manual partitioning still can't create HFS bootstrap partition https://launchpad.net/bugs/68243 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
