I have a USB drive made bootable using RUFUS and it boots my computer to DOS but it designates that drive as C:\> even when there are no other drives in the computer

How do I get it to designate the drive as A:\> ?

    I wonder if A: and B: still have code reserving them for floppy drives or whether that was removed at some point, brings back memories...

    Sam Vimes' Boots Theory of Socioeconomic Unfairness: 

    People are rich because they spend less money. A poor man buys $10 boots that last a season or two before he's walking in wet shoes and has to buy another pair. A rich man buys $50 boots that are made better and give him 10 years of dry feet. The poor man has spent $100 over those 10 years and still has wet feet.

    C: is always the boot drive for DOS and Windows.
    EDIT: but you could try and change things with

    You don't.

    Drive letters A and B are reserved for floppy disk drives, and then hard drives and removable media follows as appropriate.

    In this era of NTFS formatted drives (that DOS cannot see on its own) there is nothing for DOS to map to Drive C as a hard drive, so what follows then is the physical drives it can see and then your USB stick.

    TL;DR - this is normal behaviour.
