Note: The official Microsoft Edge VMs (now Windows 10/11 only) used to include Win7 images. You can find these archives via the Internet Archive, but verify SHA256 checksums. If you download a VirtualBox image (more common), convert it using qemu-img :

# 1. Create an empty 40GB Qcow2 image qemu-img create -f qcow2 windows7.qcow2 40G virt-install --name windows7 --ram 4096 --vcpus 4 --disk path=windows7.qcow2,format=qcow2 --cdrom /path/to/Windows7.iso --os-variant win7 --graphics spice

If you are setting up a virtual machine (VM) on , QEMU/KVM , or GNOME Boxes , the qcow2 format is the gold standard. It offers snapshots, compression, and efficient performance. But where do you actually find a safe, pre-built Windows 7 Qcow2 image?

# Convert VDI to Qcow2 qemu-img convert -f vdi Windows7.vdi -O qcow2 Windows7.qcow2 qemu-img convert -f vmdk Windows7.vmdk -O qcow2 Windows7.qcow2 Critical Driver Issue: VirtIO Windows 7 does not include drivers for VirtIO (the standard KVM disk/network drivers). When you boot your Qcow2 image, you will get a "No disk found" error.
