Die Startdateien für [Das aktuell benutzte Betriebssystem - Ubuntu 12.04.1 LTS] liegen weit hinten auf der Festplatte. Ihr BIOS könnte sie nicht erkennen. Bitte legen Sie eine Partition vom Typ /boot an und versuchen es ggf. erneut. (EXT4, >200MB, Anfang des Datenträgers). Dies könnte mit einem Tool wie gParted geschehen. Danach wählen Sie diese Partition über Option [Separate /boot-Partition:] von [Boot-Reparatur]. (https://help.ubuntu.com/community/BootPartition)
----- my translation of the last german messages -----
Boot sector was successfully repaired
You can now restart the computer
the boot script for [your current operation system - ubuntu 12.04.1 LTS] lies way back on your hard drive. Your BIOS could not recognize it. Please create a partition of type "/boot" and try again. (EXT4, >200MB, Begin of hard drive). You can do that using a tool like gParted. Choose this partition via Option [Seperate /boot-Partition:] in Boot-Repair.
Is it possible that my boot partition is corrupt (is there a way to find this out)? And why does it sometimes work and sometimes not? Any other suspicious things you can spot in this log-file?
