[CentOS] Installing Cent OS from a usb flash drive

I recently acquired a Fujitsu Lifebook 1610. Unfortunately, the machine was missing a lot of the stuff that would've come with it brand new, mainly the usb cdrom drive. Currently, I'm running Fedora on it, and I installed it using a usb flash drive with the help of a program called unetbootin(Probably not spelled right). to load the ISO onto the USB drive. I've successfully used the same program to load the Cent OS live cd onto a flash drive, and I've run it on the machine. Now, is there a way that I can install cent os onto the machine by way of the usb flash drive? I've tried the network install route, and didn't have any luck.

Thanks

Jim
