Warty live CD: GRUB error

[Christoph Bier]

Hi all!

Today I wanted to test the Warty live CD on my laptop and got the
following message:

------------------------------
GRUB loading, please wait ...
Error 21
------------------------------

This error means: »Selected disk does not exist«. But I don't
understand it, because the same live CD boots successfully on a
desktop PC and the laptop is running Debian Woody/Sarge successfully
from HDD.

Any ideas? TIA

Regards,
