I believe this bug explains why I can't boot from sda1. I installed a 'normal' Ubuntu 12.04 with Btrfs on sda1 and it worked fine. I let the installer create the partition table; GParted says it is 'msdos'. I then installed a crypt-luks Ubuntu 12.04 with /boot on sda2 (Ext2), encrypted swap on sda3, and root on sda4 (Btrfs). The 'update-grub' command finds my encrypted installation and it works fine, but it never finds the original sda1 Btrfs partition and I haven't been able to boot from it since I installed the second Ubuntu.
Output of 'fdisk -l' and 'update-grub' is attached. Martin, is there anything else you'd like to know about an effected system? Is there a work-around? ** Attachment added: "outputs.log" https://bugs.launchpad.net/ubuntu/+source/os-prober/+bug/887836/+attachment/3262812/+files/outputs.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/887836 Title: update-grub does not create btrfs menuentry in grub.cfg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/os-prober/+bug/887836/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
