In the meantime I was able to boot Knoppix and do a fdisk -l. Here is the result:

Vista was installed first, leaving some 200 GB empty for openSUSE.
The partioning is the result of openSUSE automatic installation proposal: I just decreased the size of the /home by 20 Gig to later on define a fat32-drive for easy file exchange between Vista and openSUSE.
openSUSE installed GRUP into the extended partition sdb2 when installing.
As I see the sdb1 partition (Vista) is marked active, but from Vista I do not see the sdb2 extended partition and so cannot mark it active to get into GRUB again.

That citation above is from GRUB menu.lst as I understand the sdb1 partition will be set as active by GRUB when selecting that menu Item (windows 1) - And that seems to be the point of no return since GRUP will make itself inaccesable when selecting that config item.
What can I do to make a reliable dual-boot configuration (reliable means switching between the two OSes should be possible in any directions more than just one time)???
Thanks in advance
