Virtualization is the most affordable way to run a second operating system on one PC without having to install it directly on the Data Recovery hard drive. Instead, the second OS is installed on a virtual disk represented by a special container file.
The most popular hypervisors are VirtualBox and VMware with powerful functionality and a visual graphical interface.
QEMU is a free and open source program designed to emulate software and operating systems. This tool uses hardware virtualization and has a solid list of architecture emulation support.
Here are 32 and 64-bit editions. Select the latest version of the program and download the corresponding file. We install the program, leave all the parameters by default, nothing needs to be changed.
How to use QEMU on Windows :
Unlike VirtualBox and similar hypervisors, QEMU does not have a graphical interface; it is operated through the command line. Download the ISO image of the operating system to install the virtual machine. Then you need to add the path to QEMU to the environment variables.
The list of commands and parameters for creating and managing virtual machines is quite large, just a few are enough to get started.
Run the command prompt as an administrator and proceed with the installation. First, let’s create a folder where virtual machines will be stored – C:\qemu. Then go to this folder on the command line. Next, you need to create a virtual hard disk with a capacity of about 15-20 GB.
Next, we go through the Linkedin process of installing the operating system, in my case it is ubuntu. After installation and reboot, the machine will start with the installed OS and will be ready to go.
