# ReactOS 

[ReactOS](https://reactos.org/) is an open-source operating system meant to behave exactly like Windows XP, Windows Server 2003 and later versions of Windows.

In theory, it can run any software and work with any drivers developped for early version of Windows. In practice, it is still under heavy-development and may not work as expected.

## Installation

> ReactOS is currently in **Alpha stage** and does **not** work with most virtio-devices. Performance of the display interface will not be optimal.
{.is-warning}

### Download

* *Go fetch the latest build of the *Boot CD* version of ReactOS on the official website*: https://reactos.org/getbuilds/

> Alternatively, the latest stable release could be downloaded.
{.is-info}

* *Unzip it using p7zip* (`dnf install p7zip`).

```
7za x reactos-bootcd-0.4.15-dev-3628-ga6bf77e-x86-gcc-lin-dbg.7z
``` 

* *Copy the resulting ISO under* `/var/lib/libvirt/images/`

```
mv reactos-bootcd-0.4.15-dev-3628-ga6bf77e-x86-gcc-lin-dbg /var/lib/libvirt/images/
```

### Launch the installer

* *[Clone]() the `legacy model` of virtual machine and, optionally, [rename]() it*

* *[Add the ISO file]() you just downloaded and [add a disk]() of at least 1GB using the Virtual Machine Manager*

> As of 2022, a full installation of ReactOS takes around 750Mb.
{.is-info}

* *[Power-on the virtual machine]()*

* *[Connect to the console]()*

* *Just as in the good ol' days, you need to press a key to start the installer. Notice the fact that an open firmware, [SeaBIOS](https://www.seabios.org/SeaBIOS), is able to boot an open-source NT-based kernel. A rare sight.*

> The installer supports navigation using the keyboard only.
{.is-info}

* *Choose the language for the installation process, using the keyboard Arrows Keys*

> *Amazingly, the [BTRFS](https://en.wikipedia.org/wiki/Btrfs) file system is also supported.*
{.is-info}

* *Press <kbd>ENTER</kbd> again to format the targeted partition using the selected file system.*

![reactos_installation-7.png](/screenshots/reactos_installation-7.png)

* *Once the formatting is done, press <kbd>ENTER</kbd> again to install ReactOS to the selected disk*

![reactos_installation-8.png](/screenshots/reactos_installation-8.png)

* *Wait for the setup to complete. It is fast, so there won't be enough time for a coffee.*

![reactos_installation-9.png](/screenshots/reactos_installation-9.png)

* *Once the setup is done, install the bootloader on the hard disk. The default choice seems fine. Press <kbd>ENTER</kbd> to reach the next step.*

![reactos_installation-10.png](/screenshots/reactos_installation-10.png)

> Starting now, your mouse could be used to navigate around.
{.is-info}

* *The first boot Wizard for ReactOS should eventually appear. Press <kbd>ENTER</kbd> or click on* "Next"

![reactos_boot-3.png](/screenshots/reactos_boot-3.png)

* *ReactOS relies on other Open Source projets to function, which it takes time to acknowledge. Press <kbd>ENTER</kbd> or click on "Next"*

![reactos_boot-4.png](/screenshots/reactos_boot-4.png)

* *ReactOS can behave as a server or as a workstation. If you are unsure, choose workstation. Press <kbd>ENTER</kbd> or click on "Next"*

![reactos_boot-5.png](/screenshots/reactos_boot-5.png)

* *The system language and local can be customized here. If you are satisfied with the default settings, press <kbd>ENTER</kbd> or click on "Next". Otherwise, please modify the settings.*

* *Here, you should not have to configure anything for ReactOS to have LAN and Internet access, through the newly supported `virtio-net` device. Press <kbd>ENTER</kbd> or click on "Next" to go to the next screen.*

![reactos_boot-13.png](/screenshots/reactos_boot-13.png)

* *If you wish to share files with other computers on your network, joining a Workgroup would be a first step. Press <kbd>ENTER</kbd> or click on "Next" to go to the next screen.*
