Please see the attached results. Two more comments: In a re-test I commanded Ubuntu installer to also install grub into the MBR on /dev/sdc, but bootinfo detects none. I also had no result trying to boot from that disk.
I've copied grub.cfg from the latest installation to the older installation and could boot into the latest installation. Although the older's installation UUID is visible in that grub.cfg no possibility exists to boot into the older installation, not even under the extended options for Ubuntu. ** Attachment added: "Results for bootinfo 061" https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1069470/+attachment/3408326/+files/RESULTS_bootinfo_061_20121022.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069470 Title: second install of quantal not reached To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1069470/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
