i experience this bug in quantal 12.10 daily (7/7/12). i've installed quantal, as a test, on a 8 gb stick formated btrfs as / and there everything works. Then because this worked, i decided to install it to my internal harddrive and got most likely this problem. I have seen these messages: ubuntu grub-installer: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged. ubuntu grub-installer: cannot read `/@/boot/grub/core.img' correctly" in the window below of the installer.
(see duplicate 800840) Also as above, i reinstalled from the same live envirement (didn't reboot) and used ext4 and the installation finished without a problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/879109 Title: Grub install failed on sda and sda3-btrfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/879109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
