There's a little bug in Toorox 09.2010 "GNOME" which pertains the hard disk installation.
Implication:
The installed system doesn't boot from hd ( error message from the
bootloader grub ).
Solution:
Before installation, the file device.map must be removed from /boot/grub/.
-> Boot the DVD -> click on Terminal in the panel -> type in the following:
sudo rm /boot/grub/device.map
Close the Terminal and start the hard disk installation now.
