I am new to this. I want to run an old 16-bit program on my Win 10 Pro computer. The option to activate NTVDM doesn't exist anymore in Win10, so I'm using virtualbox to set up a virtual drive with XP as my operating system. I've created the virtual drive and I have XP on an installation disc. How do I get the XP OS onto the virtual drive? Thanks for your help.

I would suggest to start by reading three small chapters from the User Manual:

• 1.2. Some terminology,
• 1.8. Creating your first virtual machine and
• 1.9. Running your virtual machine.

Or even better, read the whole chapter 1. First steps.

Actually it does. It's only the 64-bit versions of Windows which have never supported the feature, but that didn't start with Win10. The only change in Win10 is that even 32bit versions no longer enable the feature by default, you have to tick a checkbox in "Optional Features" to enable it.

p.s. You are not setting up a virtual drive. You are setting up a second PC which happens to be virtual. Almost any question you could ask has the same answer if the second PC was physical. I've found that it's really important for newbies to grasp this early on.

What kind of program is this "old 16-bit program"? DOS? Win3?
