Just to report and may be warn little bit. I was installing openSUSE aside already existing Windows 7 on new Dell notebook. For some unknown reason it was set up to use legacy BIOS, so no UEFI, no secure boot. I don't know why, I didn't do it, it wasn't my notebook. And I couldn't just reinstall Windows. I started to install 13.2 and disk partitioner offered to shrink Windows part and use Btrfs. I accepted defaults as it looked correct. Installation failed in the last step during installation of GRUB2. It correctly determined it has to use GRUB2 and not GRUB2-EFI. But it seems „plain“ Grub2 doesn't work with Btrfs. Finally I managed to push GRUB2 there, but on the first boot it failed saying „Wrong filesystem“. So I reinstalled openSUSE using EXT4 this time and it worked perfectly. Both systems are working fine. So I wonder if it is my lack of knowledge that GRUB2 doesn't work (apparently) with Btrfs or it is a bug as installer should (although I have no idea how) determine it during installation and not to recommend Btrfs. What the experts think? All the best, Vojtěch -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux http://www.opensuse.org/ http://trapa.cz/
