Running a second operating system on your Windows PC sounds hard, but it does not need a second computer. This qemu download for pc guide walks you through the free virtualizer, from the official Windows installer to your first virtual machine. QEMU lets you run Linux, an older Windows, or even a system built for another processor, all inside a window on your own PC. You will learn where to get it safely, how to install it, and how to boot a guest system for the first time.
What Is QEMU?
QEMU, short for Quick Emulator, is a free and open-source machine emulator and virtualizer. It creates a virtual computer inside your real one, with its own processor, memory, disk, and screen. You can install a guest operating system on that virtual computer and use it without touching your main Windows setup. Developers use it to test software, and hobbyists use it to try Linux or old systems safely.
Unlike a dual-boot setup, QEMU keeps everything in files on your disk, so nothing changes on your real PC. On Windows, it can use the Windows Hypervisor Platform for faster speed, and it supports many guest systems, from Windows and Linux to ARM and other processor types. The catch is that QEMU is mostly driven from the command line, so this guide keeps the commands short and simple.
Key Features
- Runs many operating systems: Linux, Windows, and systems for ARM, PowerPC, and other processors.
- Hardware acceleration: uses WHPX on Windows for near-native speed when it is turned on.
- Disk images: stores each virtual machine in a single file you can copy or back up.
- Snapshots: save a VM state and roll back in seconds if something breaks.
- Network options: connect a guest to your network or keep it isolated.
- USB and device support: pass USB sticks and other hardware through to the guest.
- Open source: free forever, with no account and no paid edition.
System Requirements
- Operating system: Windows 10 or Windows 11 (64-bit)
- Processor: a 64-bit CPU; virtualization (VT-x or AMD-V) turned on in BIOS for best speed
- RAM: 4 GB minimum; 8 GB or more is better for running a guest smoothly
- Storage: at least 20 GB free for QEMU plus space for each virtual disk
- Network: an internet connection to download QEMU and guest ISO files
- Extras: a guest operating system ISO file, such as Ubuntu, to install in the VM

qemu download for pc: How to Create a Virtual Machine with QEMU
First, download an ISO file of the guest system you want, such as Ubuntu, and create a blank virtual disk with qemu-img. Then run qemu-system-x86_64 with the disk and the ISO attached, and the guest installer will boot inside a window. Once you finish the install, start the VM again without the ISO, and the guest will boot from its virtual disk. If you have just completed the qemu download for pc and installation above, you are ready to begin.
- Download a guest ISO, such as Ubuntu, and save it in a folder.
- Open Command Prompt and create a virtual disk: qemu-img create -f qcow2 disk.qcow2 20G
- Start the VM with the ISO attached: qemu-system-x86_64 -hda disk.qcow2 -cdrom ubuntu.iso -boot d -m 2048
- Wait for the guest installer to appear in the QEMU window.
- Follow the guest installer and install the system onto the virtual disk.
- Shut down the guest, then start it again without the ISO: qemu-system-x86_64 -hda disk.qcow2 -m 2048
- Use the guest inside the QEMU window, and close the window to stop it.
