A system and method is disclosed for identifying at least one bootable USB device coupled to a computer system across multiple reboots of the computer system. A four-byte signature for each bootable USB device is generated by performing a hash function on a Device Identification Number, a Vendor Identification Number, and at least a subset of a Serial Number, all of which are associated with that bootable USB device. The four-byte signature for each bootable USB device is saved in a BIOS boot order table located in a non-volatile storage unit in the computer system.
