This is in fact what I've decided to do and it does work. In the same FAT16 (aka FAT) partition on the boot drive, in one directory called windows I have Win 98, and in another directory called winnt I have Win NT. I can dual boot without problems using shared applications and data as long as they are installed on a FAT16 drive. MathWorks MATLAB GUIs with MATLAB 5.2.1 work fine under Win NT 4.0 but lock up under Win 98 if there are checkboxes in the GUI.
