As I just reviewed this, I wanted to add, that the line "/usr/sbin/grub-setup: info: »/boot/grub/device.map« kann nicht geöffnet werden."
in attachment grub-install.log would be "/usr/sbin/grub-setup: info: »/boot/grub/device.map« cannot be opened" in English. Usually the file really doesn't exist, but one time (before this very time) I tried to build that file by invoking grub-mkdevicemap manually. The overall result was just the same. Apart from this the device mapping seems to be correct anyway. The rest of the log should be mostly in English... Is it possible, that grub-install fails to determine the correct position to write? Maybe it installs in sda2 or sda5 or even worse: somewhere in my data? Is there any risk in invoking grub-install this way regarding the consistency of my data? PS: While testing this, there was a memory stick (sdc, 3 partitions, including one live system) and another hard disk (sdb, just backupped data, no system, no boot loader) present. I cut those parts out of the RESULTS.txt, but some lines in grub-install.log still give evidence of this... ;) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/574883 Title: Grub doesn't install to partition boot record (PBR) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
