How to create virtual dos machine for windows 7?


Hello Corey,

You will need to go to with either VMWare Player or Virtualbox, and Windows Virtual PC can work on Windows 7 Home Premium, but when you set up MS-DOS on it will be more involved as compared to the other VM solutions. Note that any Windows edition will do, be it  Home Premium, Professional or Ultimate.

Memory is considerably cheap, and therefore in case you can get a minimum 4GB it will be more recommended that you go with it and as well ensure that it has a 64 bit version of Windows 7. The CPU that is recommended is Intel Core i3 or higher.

How to create virtual dos machine for windows 7?


Creating a DOS virtual machine means installing DOS on the created virtual machine. Normally when creating a virtual machine, your computer should be sufficient enough to handle or provide what is required by the virtual machine. But since you only want to create a virtual machine that runs on the old DOS operating system, you probably don’t need a high-end computer.

To create a DOS virtual machine, you need to install VirtualBox. You can also use VMware but in this tutorial, we will be using VirtualBox and DOS version 6.22. First, download and install Oracle VirtualBox. Select the download for Microsoft Windows hosts. See image.

Once VirtualBox is installed, download the DOS image files from DOS 6.22 Images. After that, start VirtualBox then click New located on the upper left corner of the screen. Click Next then label or give your virtual machine a name for example DOS and then click Next. Allocate some RAM for your virtual machine. For example, 64 MB since it is the most common that DOS 6.22 sees.

If you want, you can select a much lower value. After that, click Next and then click Create New Disk. Click Next then select a virtual hard drive format. Usually, the top option works fine but you can select a different one. Click Next. Select between dynamically allocated and fixed size. Dynamically allocated allows your virtual hard drive to grow or shrink as you add or delete files.

This is slower. Fixed size is faster because the size of the drive is constant and doesn’t change like the usual hard drive on the computer. Click Next then select the size of the virtual hard drive. Selecting dynamically allocated will require you to set the maximum size of the drive. Click Next, Create, and then Create. Once the virtual machine is created, right-click on the virtual machine then select Settings.

Go to System then select Acceleration tab. On this tab, make sure all boxes or options are unchecked. Go to Display then configure the amount of video RAM to use. For example, set it to 8 MB. You can actually select any amount above the red. Go to Storage then click Add Controller and then “Add floppy controller”. Click Add Floppy Device then click Leave Empty on the next screen.

Go to Audio then set it to “SoundBlaster 16”. Select the Network tab then choose Bridged Adapter and then select your network adapter. Next is the installation of the DOS operating system. Double-click the virtual machine you created then click Devices. Point to Floppy Device then click “Choose a Virtual Floppy Disk File”. Navigate to the folder where you downloaded the DOS 6.22 image files then double-click disk 1.

Close all the windows in the virtual machine then click “Power off the machine” and then OK. Double-click the virtual machine again then when you are prompted to insert disk 2 and 3, repeat the steps in installing DOS 6.22 operating system.
