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. in Computerswith bootbootabledosdrivehowtousbby 2 users
