Boot EuroOS on your own machine.

① QEMU , recommended

A self-contained bundle: the EuroOS image, the UEFI firmware, and a one-click launcher. It sets up networking and a persistent disk for you.

1. Install QEMU, apt install qemu-system-x86 qemu-utils · dnf install qemu-system-x86 qemu-img · brew install qemu · or the QEMU for Windows installer.
2. Unpack the archive.
3. Run ./run-euroos.sh (Linux/macOS) or double-click run-euroos.bat (Windows).

The launcher uses KVM (Linux), HVF (macOS) or WHPX (Windows) when available, that’s what makes it boot in seconds. Without acceleration it still runs, just slower.

② VirtualBox

Download the disk image, then create a VM with EFI enabled.

1. Decompress the .vmdk.gz.
2. New VM → Type “Other”, Version “Other/Unknown (64-bit)”.
3. System → Enable EFI.
4. Storage → attach the .vmdk as the hard disk.
5. Network → Adapter 1 → Paravirtualized Network (virtio-net), then start.

VirtualBox’s EFI is more finicky than QEMU, if it doesn’t boot, use the QEMU bundle.

③ Cloud, Whitesky.cloud, OpenStack, or any UEFI VM platform

A standard qcow2 cloud image. Upload it as a custom image/template, boot with UEFI firmware and a virtio disk + virtio network interface, the desktop shows over the platform’s console/VNC.

④ Raw UEFI image , latest build

The newest development build as a raw UEFI boot image (FAT32, x86-64). Write it to a USB stick to boot real hardware, or attach it directly as a raw disk in QEMU or any hypervisor, the freshest desktop build.

1. Decompress: gunzip euroos-x86_64-uefi.img.gz.
2. USB: sudo dd if=euroos-x86_64-uefi.img of=/dev/sdX bs=4M status=progress, check lsblk first; this erases the target!
3. QEMU: qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -drive format=raw,file=euroos-x86_64-uefi.img -m 256M.
4. Boot the machine/VM with UEFI firmware (not legacy BIOS).

Built from the current source tree. This build lands EuroOS’s modern-hardware (“Metal”) layer: it now installs to and boots from an NVMe or SATA disk (a modern, NVMe-only laptop runs standalone from its own disk), with from-scratch drivers for NVMe, AHCI/SATA, Intel e1000 and USB ethernet, USB hubs and USB audio, the ACPI power button, and TPM 2.0 over both the discrete (TIS) and firmware (CRB / fTPM / PTT) interfaces. Peripherals are network-first: driverless printing (IPP Everywhere) and scanning (eSCL), no per-vendor driver. And it plays DOOM, the real 1993 engine, as an unmodified userspace binary. It also carries the full sovereign-trust layer. The full-disk-encryption and secrets-vault keys are now sealed inside the TPM and released only on an untampered, measured boot; the VPN uses post-quantum hybrid key exchange (X25519 + ML-KEM-768, checked against the NIST vectors) so recorded traffic stays secret against a future quantum computer; EuroID can act as an eIDAS 2.0 digital-identity wallet with selective disclosure; the system image is protected by a signed dm-verity hash tree; time is authenticated (NTS); and every security event is written to a hash-chained, tamper-evident audit log. On the distribution side it adds a signed, rollback-safe update-delivery channel, multi-user sessions with per-user disk quotas, a signed package manager, a reproducible, Ed25519-signed release pipeline, and a GDB serial stub. The office core now opens and saves real .docx files (via a from-scratch DEFLATE), the system speaks all 24 EU languages (month and weekday names) with AZERTY/QWERTZ keyboard layouts, it knows what every file is and which app owns it (MIME + default-app), it has an audio mixer with per-app routing, and access to the camera, microphone or your files is capability-brokered: an app is granted it explicitly and per action (once, this session, or never) through the system permission portal, never as ambient access; every read of the system image is verified against a signed hash tree; the system journal survives a reboot; and a deadman watchdog catches a hung system. Sovereign data-control by design. Under the hood: a structured journal with crash capture, a deadman watchdog, a kernel-hardening baseline, continuous fuzzing, and DHCPv6 / mDNS / DNSSEC networking. Everything from before is still here: reads and writes FAT and exFAT, reads ext4, auto-mounts USB sticks, opens Windows (SMB) and NFS shares; secure A/B self-update with automatic rollback and Ed25519-verified images; the crash-consistent EuroFS; the GUI lockscreen (EuroID · memory-hard Argon2id); Zero-Trust for AI agents; the stateful firewall + forward-secret VPN; GNU-compatible coreutils; the live display server; and fail-closed TLS.
