China DOS Union

I have downloaded the MS-DOS7.1.IMG file (1440KB)
I want to make this IMG file into a bootable MS-DOS7.1.ISO image file
① I don't know what tool to use?
② How to do it?

This should be an image file of a 1.44 floppy disk.

You can use UltraISO.
1. First, open your MS-DOS 7.1.IMG file with UltraISO, select all the files in the right box above, right-click - Extract, and extract all files to a folder for saving.
2. New - Bootable CD - It will prompt to load the boot file - Open your MS-DOS 7.1.IMG. Then find the folder you saved in the previous step in the left box below, select all the files in it - Right-click - Add, add all to the box above, and finally save it.

Thank you very much 2gg!!!!!!!!!!!!!!!
