These are the relevant errors: EXT4-fs (sda2): INFO: recovery required on readonly filesystem EXT4-fs (sda2): write access unavailable, cannot proceed
Unfortunately, there is no way to mount an ext3 filesystem that requires recovery without replaying the journal and thus causing writes to that partition. os-prober used to replay the journal, but that caused serious data-loss bugs in some cases so we stopped doing that. The workaround is simply to perform recovery on the filesystem in question using the 'fsck' tool. I regret the need for this, but unfortunately the alternative is worse. As for why your Maverick system always needs recovery, I can't say. Perhaps it isn't shutting down cleanly? ** Changed in: os-prober (Ubuntu) Status: New => Won't Fix ** Changed in: os-prober (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/683355 Title: Natty os-prober fails to detect Maverick installation -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
