I've just been hit by this bug when installing Ubuntu Lucid 10.04 from the alternate ISO image (64 bits) in a Dell Lattitude E6410. It came with three primary partitions. Dell Utilities in sda1, Windows 7 Recovery in sda2 and Windows 7 in sda3. I created an extended partition and install Ubuntu there.
Grub shows now all the Ubuntu starting options correctly, but the only extra option that is shown is Windows 7 and wants to star from sda2. It doesn't show the actual Windows 7 partition nor the Dell Utilities partition. In an older Dell Latitude that I have grub legacy had identified all the partitions correctly. -- Grub2 affected when os-prober incorrectly identifies Windows and Recovery partitions https://bugs.launchpad.net/bugs/476625 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
