It should go to the raw disk device, not a partition and you shouldn't need to format first.
The reason I re-formatted it was that fdisk said there was no valid partition table after dd-ing bootdisk.img onto /dev/sdb .
I thought small usb devices generally didn't have a partition table and just have one filesystem on the raw device. But I don't have a lot of experience with them. In any case the img file should have whatever needs to be there.
I guess you could try grabbing a different copy from a mirror site like: http://centos.cs.wisc.edu/pub/mirrors/linux/centos/5.5/os/i386/images/
I'll try again, now that I'm sure what you mean.
That was just in case your source copy had a problem.
Incidentally, I also tried livecd-iso-to-disk boot.iso /dev/sdb1 but on re-booting there was just a ";" on my laptop screen. (The BIOS was set to use the USB stick, and in fact started fine with CentOS Live USB and Fedora Live USB.)
There's probably some clever way you could use your live USB that works to install a copy of the boot.iso files on a partition on the hard disk and make grub boot it, but the usb img file is supposed to work.
