Per Thomas Schwinge's reply, you have a hardware issue.
Suggest that you ask how to problem solve when booting.
Might be a flag that spits out debug messages that may point to your hardware issue.

Good luck and happy new year

Yes, it might be a hardware issue. I installed qemu and I was able to boot the Hurd. I'll see if I can get it working with virtual PC too. Thank you for your help.

GRUB tells me, that /boot/gnumach.gz resides on (hd0,0) and since
there is no error message after typing
"kernel (hd0,0)/boot/gnumach.gz", I guess that GRUB finds the kernel.

Thank you for these links, I noticed, that other people use a GRUB
floppy image while I use
a full featured (multi language) GRUB CD image. Could it be possible
that the version of
GRUB I use is missing something and therefore is unable to boot Hurd?

I already tried the -s switch, but I think it should not have
anything to to with the bootstrapping problem I
currently have.

Not yet. :(
