Making USB boot on Ubuntu

[Liquid~]

Hello everyone! I have been just a silent member here for a long time now and finally I got Ubuntu up and running (7.10 by the way) and I decided to try BackTrack a little, so I downloaded BT3 usb boot from remote-expoilt.org and tried to install with the instructions but all I get out (well, also you have typo in instructions "run ./boostinst.sh" at least I think it's typo ^^):

$ ./bootinst.sh
./bootinst.sh: Permission denied

Also I all ready tried forums.remote-exploit.org/showthread.php?p=63315#post63315 but I keep getting:

lzm2dir: command not found

So please help noob out will ya' I'd really would like to try BackTrack out at my school , so... tell me what I am doing wrong here.

right click on the file and try and change the file permissions and set the file to executable

try that or type:
sudo ./bootinst.sh
