Hello list. I wanted to install kubuntu 14.04 on a USB-Stick which was mounted as /dev/sdbX at my productive laptop which uses /dev/sdaX. I choosed all options regarding to /dev/sdb but after install my laptop was not able to boot anymore since all data at the beginning of /dev/sda seems to be overwritten. I need to recover and make it boot again. The laptop (new dell 64 bit) is also running a kubuntu 14.04.02 system. The setup is: I have a luks encrypted disk which I am able to encrypt using cryptsetup open /dev/sda3 kubuntu-vg On top of it is lvm2 sitting, which I am able to activate using vgchange -ay One volume group kubuntu-vg is displayed and I have 2 logical volumes (kubuntu-vg-root and kubuntu-vg-swap_1). I can mount it via mount /dev/mapper/kubuntu--vg-root /mnt/ When I look at /mnt/boot, I have 2 dirs there: efi and grub
When using fdisk -l I get folling partition layout: /dev/sda1 2048 1050623 512M EFI System /dev/sda2 1050624 1550335 244M Linux filesystem /dev/sda3 1550335 1953523711 930.8G Linux filesystem I am afraid of breaking things more. Also I do not know, how everything is working. Are the first sectors of /dev/sda just a pointer to the rest of the booting code which resides at /dev/sda2? Please help. What can I do? What further information could be helpfull? Stefan _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
