How to Make an MS-DOS Bootable Floppy Disk for Hyper-V or VPC
If you are stuck trying to do this, you would be surprised at how quickly it can still be done. The Challenge is getting a boot sector – which you can override with a new set of MS-DOS files if require a specific version.
1.) Mount a Blank VFD
2.) Start a Windows XP VM.
3.) Attach a VFD to the XP VM after you have logged on to the XP VM.
4.) Right-click the floppy in the Windows XP Guest OS and select Format.
5.) Check the option to create an MS-DOS System Disk.
Post format you can do whatever you need to copy over the files on the disk if you need an older version such as MS-DOS 6.22. Overwrite files as needed as all you needed from step #5 was the creation of the boot sector.
