Note: grml2hd doesn't do any partitioning nor does it provide an interface to 
do so, that's why 'No hard disk partitions found' usually shows up if you don't 
have an according partition setup yet.

According to your hwinfo the live system just recognizes the 32GB USB flash 
drive attached to your box. Does booting with the failsafe bootoption change 
anything?
