Hi Joep,

well, what Patrick meant is, that your system (forget that USB drive in
this moment) already has a VG called VolGroup00 on your internal disk.
The modern FC distros use it as default (i think, i'm using SuSE ;-) ).
Before messing up more using fdisk, just provide us with the output of a
vgdisplay -a ;-) get an impression of the 'disaster' :-).

Btw. the volume group your wanted to create has the name VG0, not
VolGroup00 ;-) ..

Ciao
Klaus
