DOS, or Disk Operating System, is a type of operating system (OS) used primarily in the 1980s and 1990s. It is an early, low-level operating system designed for 16-bit x86-compatible processors, such as those in the original IBM PC and its clones. DOS has since been replaced by newer, more advanced operating systems, such as Windows and Linux.
While DOS has been largely phased out in recent years, it is still occasionally used in specialized scenarios, such as retro gaming or maintaining legacy systems.
To use DOS, follow these steps:
Obtain a DOS disk image: DOS cannot be directly installed on modern computers. Instead, you need to obtain a DOS disk image (a digital copy of a physical disk) from a reliable source, such as the Internet Archive or OldComputers.com.
Convert the disk image to a bootable USB drive: You will need software like WinImage, Rufus, or UNetbootin to convert the disk image into a format that can be burned onto a USB drive. Make sure your computer’s BIOS settings allow USB booting.
Create a bootable USB drive: Once you have the software mentioned in the previous step, use it to create a bootable USB drive using the converted disk image. This process will essentially install DOS on the USB drive.
Boot your computer from the USB drive. Restart your computer and access its BIOS settings. In most PCs, it varies how to change the boot drive, however, it is allowed to study every machine’s boot-up system settings. The PC will now load in DOS.
Please note that attempting to run DOS on a modern computer may result in unexpected behavior or even system instability. It is recommended to use a virtual machine, such as DOSBox or PCem, to emulate DOS if you wish to run it on a non-dedicated hardware basis.
