DOS Bootable USB flash drive - how I did it : Perley's Pontificating Place There are 2 things you need in order to make an USB flash drive boot into DOS. The first is a boot sector, and the second are the DOS boot files. Below are the steps I used to get these onto a USB flash drive, making it possible to boot into DOS from the USB flash drive. The following steps where all done in Microsoft Windows XP in a VMware virtual machine. They should work with most other versions of MS Windows. I successfully used these steps on an USB flash drive I got at Immersion Week 2008 for use in a ZFS demo (Identifies itself as CBM). YMMV depending on USB flash drive model and manufacturer. These steps are based off of the very useful information at BootDisk.com. By henrikin Computerswith bootbootabledosdrivehowtousbby 2 users
