Hi,

please see fdisk output:

fdisk -l /dev/sdb

Warnung: GPT (GUID-Partitionstabelle) auf '/dev/sdb' erkannt! Das Hilfsprogramm Fdisk unterstützt GPT nicht. Verwenden Sie GNU Parted.

And: grub-setup --force brings the same error.

Hi,

I have a configuration with two HDDs.
First HDD = encrypted Windows (Truecrypt)
Second HDD = encrypted Ubuntu + encrypted NTFS partition

It worked to boot into ubuntu by selecting the second hdd in the bios boot-menue. To boot into ubuntu via the Truecrypt boot-menue does not work - but I don't care at the moment.

After some system upgrade (apt-get update && apt-get upgrade) I answered a question regarding grub the wrong way and now I am not anymore able to boot into ubuntu.

With supergrub-disk I am able to start ubuntu. But I cannot get grub2 installed on the mbr of the second hdd.

Configuration:
lsblk

grub-setup /dev/sdb
grub-setup: Warnung: This GPT partition label has no BIOS Boot Partition; embedding won't be possible!.
grub-setup: Warnung: Einbettung ist nicht möglich. GRUB kann in dieser Konfiguration nur mittels Blocklisten installiert werden. Blocklisten sind allerdings UNZUVERLÄSSIG und deren Verwendung wird daher nicht empfohlen..
grub-setup: Fehler: mit Blocklisten wird nicht fortgesetzt.

I neither can identify the message I get nor find a solution for that.

And could you show "fdisk -l /dev/sdb"? GRUB2 believes this is GPT diks. If it is true, you need to either create BIOS Boot Partition to embed grub2 or use --force to continues with (not recommended) blocklist.
 
To recall: After basic installation of the whole environment it worked. But you might imagine to delete the second hdd and start from scratch is not the very best solution for me.

I would appreciate any help.
