Cut an image onto usb key

Howdy all,

I am wondering if someone can help.

Years ago, I used to use ghost to create an image onto cd and image a machine by popping it in and booting.

It has been so long and ghost has changed so much.

I have Ghost 15.0 and I wan to cut an image onto a usb key and image from that.

My system supports booting from usb and I use ultimate boot cd often from usb.

Any suggestions as to the best way to cut an image onto my key and just pop it in to re-image?

Any help would be appreciated!
Thanks
