that should work.
There is another way but its kinda oldschool. It involves a floppy disk and taking the files that are on if after you formatted it as a bootable disk and putting them on the USB stick.
If the bootable .iso doesn't work. post back and I' explain the other process in better detail and leave you some links.
It's a little more complicated than that -- you have to make the USB bootable (put a bootsector on it) - you can't just copy the files from the CD onto it.
Are you installing linux? If so hewre is a good guide:
it's for gentoo - but I think the basic instructions are the same.http://www.gentoo.org/doc/en/liveusb.xml
Here is a good page of tutorials for just about any distro that you want to install from a flash drive:http://www.pendrivelinux.com/
