You need to create an ext4 partition and a swap partition. Then install bt5 with "Manually" option when running "BT5 Install" from desktop.
To create a ext4 and a swap partitions, you need to download gparted and burn it onto a CD or from the USB BT5, open up a terminal and type gparted..If it's not in USB BT5, you must find it in the DVD live or as I said, download the gparted.
Luck.
