Can't install GRUB2. LDM has no Embedding Partition

Dear people,

I am a beginner in Linux and i have a question.
My setup is as followed:

2x 500 gb hard disk RAID 0
1x 500 gb hard disk Which my BIOS also sees as a raid drive
1x 1000 gb hard disk which my bios sees as a sata drive.

So, I've installed Windows 7 on my 2x 500 gb hard disk with RAID 0.
Now i am trying to install OpenSUSE 13.1 on my 1x 500 gb drive which my BIOS also sees as a RAID 0 drive.
During the installation of OpenSUSE 13.1 at like 93% the following error occures:

Error occurred while installing GRUB2.
/usr/sbin/grub2-bios-setup: warning: this LDM has no Embedding Partition; embedding won't be possible.
/usr/sbin/grub2-bios-setup: erro: embedding is not possible, but this is required for cross-disk install.

I have no clue what to do now and hoped somebody could help me out :).

Thanks a lot guys!
