Installing a boot disc Aaagh!

Having finished setting up as far as I can go, machines locked away, thought I'd set up a boot disc for the new Asus Builds. Best laid plans of mice and all that as I am forced into the realisation that my current flash disc just isn't big enough by nearly a gig. Decided to take it home and get a ned disc on the way. Unless...... hmm maybe they have one in the office... The yawn will continue...
