linux doesn't have a gui so you always start up in dos mode. just use linux.

1 - you will need two things: the dos distribution (dos 6.22, google or isohunt dos622.rar) and a dos boot disk image (google here). format your flash drive as FAT (not FAT32).
use Run->Cmd->Format [flash drive letter] so you can get some output.
note - if your flash drive has 2048 byte sectors (read format command output) instead of 512 byte sectors i don't think this will work. if your flash drive is >2GB you will have to partition it.
2 - make a dos boot floppy from the image file.
2.1 - copy the following from the dos distro if it's not already on the floppy: SYS.COM, FDISK.COM, FORMAT.COM. If you have to delete files do not touch COMMAND.COM, IO.SYS, or MS-DOS.SYS.
3 - enable legacy usb mass storage device support in your bios.
4 - boot the dos floopy
5 - check drives, C:, D:, E:, etc. and try to find your flash drive. your system drive should not show up if it's ntfs
6 - once you've found your drive, type SYS [drive letter]:. Should say "System transferred" if all is well. Drive is now bootable.
7 - run FDISK and partition your drive if you want or need to.
8 - i'd format again just to be safe, using the MS-DOS format command
9 - boot back to windows and copy the dos distro to a suitable dir on the flash drive (DOS622 orsomething)
10 - you need to make autoexec.bat and config.sys files and probably want to get some basic drivers and utilities at this point. good luck!
