Yes, that did the trick. Now with (hd0,0) it boots on sdb1, where 
(hd1,0) tries to boot on sda1 - the sata-harddisk.

Maybee (hd0, ) is just the first disk in the boot-sequence.

Next question to someone : can I get this grub to boot from an iso-file 
like grml1.0 or even Knoppix or BartPE on the flash-pen ?
