Sorry if this information is already in the many comments,.
I cloned my "C" drive to a travel drive (150GB seagate attached via USB). My HP doesn't have the recent BIOS additions for USB Booting.

Since the clone has all the Windows booting stuff in the right place, plus all my applications and data, would like a simple "bootstrap" on a Floppy or Flash Drive which would effectively start the boot, then switch the input to the assigned or selected travel drive

Any tips? tia Howard
