Try FreeDOS from a USB without installing it: how you do it

When starting our computer from scratch, the first thing we must do is select an operating system. We can choose between several very interesting alternatives such as Windows, a Linux distribution , FreeDOS, etc.

In fact, in these same lines we want to focus on the last version mentioned, this simple, but at the same time useful free operating system. And it is that its top managers have just sent us a new version with interesting news that will surely attract the attention of many. Specifically, we are referring to the new FreeDOS 1.3 that has been released to improve in terms of becoming the substitute for MS-DOS, but open source. This recently sent version was expected by many of the regulars of this software.

Keep in mind that FreeDOS 1.2 was made available to everyone some time ago, at Christmas 2016 . So now, half a decade later, the new FreeDOS 1.3 is finally within reach to be an ever better open source alternative to MS-DOS. Considering that the previous version of the open source system has been around for several years, many will want to upgrade as soon as possible. Therefore, the first thing we need to know is that the new version is based on Kernel 2043 .

At the same time we will have a version for 8086 with support for FAT32 and a wide variety of improvements. When we buy a new computer, on many occasions to start it we find this operating system. In parallel, it has been used for a long time to enjoy classic DOS games or other tasks such as flashing some BIOS from old motherboards.

This is how you boot the new FreeDOS 1.3 Live image

But there is no doubt that one of the main novelties that we are going to find in this release is the possibility of using a Live image of FreeDOS 1.3. This will allow us to create a USB and boot the operating system as we usually do on many occasions with Linux distributions.

To say that all this is already available for download with FreeCOM 0.85a , some new programs and games , package updates and improvements. In addition, it integrates an improved installation process with the MBR, and the possibility of using, as we mentioned, a Live image to boot the system. It is for all these reasons that we will now explain how to boot the new FreeDOS from a USB image thanks to this possibility now included.

  • Download the Live version of FreeDOS 1.3 from its official website .
  • Choose the desired version between LiveCD, FullUSB or LiteUSB, although in this specific case we are interested in LiveCD for the boot we are looking for.
  • Download the Rufus program to create the Live USB of the operating system.
  • Connect the memory to the PC port.
  • Configure Rufus by choosing the USB drive in question, the partition system and the Live system to boot after, in this case FreeDOS 1.3.
  • Change the boot in the BIOS of the PC and put the USB port first.
  • Connect the stick and boot the computer with FreeDOS 1.3.

All this will allow us to directly start our PC with this open source operating system to test its operation, for example.
