Making Kingston DataTraveller G2 bootable in linux

I bought a Kingston DataTraveller to transfer EasyPeasy onto my Asus EEE pc in place of it's Xandros operating system. After I downloaded the EasyPeasy iso and put it onto the usb stick with unetbootin I tried to boot into it from the AsusEEEpc but it would not boot from it. I ended up launching GParted. In that you can right click the usb drive and there is a dropdown that says "Manage Flags". I clicked that and clicked the checkbox next to the boot flag. After placing the iso on the drive again using unetbootin, it booted, and now I have ubuntu mobile on my EEEpc :)
