thank you very much for your hint.
The device-map shows that /dev/sda  corresponds to hd1.

does now the job. However, when rebooting the PC from the external disk, the 
boot procedure stops after a message "grub loading stage2" with the 
prompt "grub>". That is all.
stage1 and 2 are in /dev/sda5/grub, as well as menu.lst
Could stage1 and 2 be wrong ? I copied them from my 
original /usr/lib/grub/i386-pc/
