I think if you want to learn, you must first install the DOS system on your machine.
As for how to install, there are many materials on the Internet. Everyone should check by themselves. The process of checking is a process of answering doubts. For example, I successfully installed MS-DOS. Since only the C drive is in FAT32 format and the other drives are in NFTS, naturally I can't directly access the other drives? What to do? Everyone should find a way.
In this process, many doubts come out, such as what is a file system and so on. Everyone should have a spirit of not being afraid of "sacrifice". Don't be afraid of damaging the machine.
