how to use the pcbsd9.0 usb as a live session cd

[rvc]

i ve downloaded and made a usb stick from pcbsd9.0-usbfull-x64.img. i am able to boot of the usb but it redirects to the installer.

i have windows 7 on my primary c, and am running linuxmint13 64 bit from other partition.

question 1. can i use the usb stick as a live session cd before i go for a clean install on the harddisk

question2. can i use a triple boot with this pcbsd version along with win7 and linuxmint13 ? and if i can, how do i go about installing pcbsd on my available free partition ?

question3. the installer does not recognise the free partition (which is currently in ntfs) how to make the installer identify the total disk volumes so i can format it to the required ufs filesystem where i can install pcbsd and be able to choose from 3 OS using the triple boot option.

i am totally new to pcbsd and would appreciate if some guidance is provided in this direction.
