I have an idea, but do not know if it will work. I want to use Windows prior to XP, but, since Windows 2000 does not have a bootstrap method (at least, none that I can recall), I have decided upon using Windows 98.
I have two operating systems on this machine already, Ubuntu and Windows 10. I also have a separate Data Partition. Is it possible to run Windows 98 under Windows 10, as a program perhaps, or dual booted sharing one partition? Or would I need something more complex? Do I need another disc partition for Windows 98?
Note that I'm wanting to run it, when I bootstrap it, as the primary operating system on the bare metal, not virtualized.
Triple-Boot + 4 partition Limit is a similar question, but note that I'm choosing Windows 98 as my third operating system, not Windows XP. Similarly, How to Triple boot deals with Windows 7, not Windows 98.
