I came across the program RMPrepUSB http://www.boot-land...;showtopic=7739
I can successfully create a USB bootable FreeDOS key.

I came across the web site PenDriveLinux http://www.pendrivel...usb-in-windows/
I can successfully create a USB bootable Ubuntu Linux key.

The problem is that I can't make the key boot FreeDOS and Ubuntu. PenDriveLinux uses syslinux for boot menu.
Any ideas on how to do this? I am trying to create the USB dual boot key from Windows, and then type instructions for others to follow.

You need to take a choice, are you wanting to use:
  • grub4dos
  • syslinux
  • both



  • grub4dos can directly chainload the freedos kernel and any Linux kernel
  • syslinux can directly chainload any Linux kernel (cannot say about freedos, but in the worst case it can use a bootsector file .bs)
  • grub4dos can be started as grub.exe from freedos and then chainload the linux kernel
  • grub4dos can be started as grub.exe from Linux and then chainload the freedos kernel
  • grub4dos can load syslinux
  • syslinux can load grub4dos
