I don't know what we have in the way of tutorials on this subject but--
this link covers two situations.
shadowbox | 2010 wave for developers : Quickstart: Creating a Bootable USB Drive
Personally, I've always rolled my own-basically, using DiskPart and knowledge of format required in the two cases.
However, if we don't already have something here, then this and/or a link to the .zip file which contains the iso/os folder to usb stick might be worth noting if someone asks-How do I make a usb stick bootable? How do I put my Win7 DVD or Iso onto USB.
