That's not really what I've asked xD I asked you to enter directly into the
partition if it was possible. And this using nautilus or the terminal like
this :
mkdir /mnt/partition1
mount /dev/sdaX /mnt/partition (replacing X by the partition number)
ls /mnt/partition1
You need to install it on the /dev/sda so it could override the Windows MBR
and use Grub instead. (Be aware that if you have a "non-official" copy of
Windows re-replacing grub by MBR could make you loose the genuine state...
But I never said that to you :D)
