Auto-detection of a filesystem of /dev/mapper/vg-striped failed. Try with --recheck. If the problem persists please report this together with the output of "/usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs -v /boot/grub" to <bug-g...@gnu.org> Output of grub-probe command above is attached. Everything was fine until I installed another OS in a pre-existent partition. Now I can't put grub back in the MBR and I must use a usb stick to boot. My root - partition is a 3-disk-LVM volume and has /boot. + partition is an ext4 3-disk LVM volume and has /boot. # fdisk -l /dev/sdb Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000571a2 - Device Boot Start End Blocks Id System + Device Boot Start End Blocks Id System /dev/sdb1 * 2048 62916607 31457280 7 HPFS/NTFS/exFAT /dev/sdb2 62916608 1953525167 945304280 8e Linux LVM -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1027363 Title: grub-install fails with "out of disk" error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1027363/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
