1. Introduction

The Windows installer allows you to install Q4OS alongside Windows in an easy way, you won't have to modify your existing Windows operating system, nor any of your software installed. Once you install Q4OS, you'll be able to switch back and forth between Windows and Q4OS each time you restart your computer. This installer is compatible with Windows 7, 8 or 10 versions and it's able to use Secure boot if available in the PC firmware.

If your Windows becomes lagging, it's the right time to try Q4OS out, a lightweight, snappy and easy to use operating system with variety of applications available in repositories. Q4OS is not intended to be a replacement, but the perfect complement to an existing Windows installation.


2. Installation

First, you need to download installer executable, file "q4os-winsetup.exe", from the downloads section of the Q4OS website. Launch it the usual way by double click from file manager, and follow instructions of a guide style installer. You will be asked to choose the storage space, this means how much storage you would like to assign for Q4OS in your Windows's drive. The installer will start downloading, extracting and expanding the target image file. Installation itself could take a time, from a minute up to an hour depending on the disk size selected, so please be patient. Once the installation process has finished, close the installer window and restart computer.


3. Secure boot setup

Once booted for the first time, you will be asked to enroll a MOK, Machine Owner Key, used for signing UEFI boot loaders. Please read following instructions how to enroll the MOK from the EFI System Partition:

(ESP)/EFI/debian/wubildr/user_key.cer

As the key is enrolled, Secure boot will allow you to boot Q4OS in a smooth and safe way.


4. Pull up boot menu

The UEFI version of installer installs Q4OS to the UEFI boot menu which means by default you won't see it when you boot your computer. Your computer will instead continue to boot into Windows and it will appear that nothing has in fact happened. To boot into Q4OS restart your computer and press the function key to pull up your boot menu. The following list provides the function keys for common computer manufacturers:

 Acer - Esc, F9, F12
 ASUS - Esc, F8
 Compaq - Esc, F9
 Dell - F12
 EMachines - F12
 HP - Esc, F9
 Intel - F10
 Lenovo - F8, F10, F12
 NEC - F5
 Packard Bell - F8
 Samsung - Esc, F12
 Sony - F11, F12
 Toshiba - F12

You need to tap the function key straight away and before Windows boots. This will bring up a menu and you can choose to either boot into Windows or Q4OS. If you choose Q4OS from this menu then Q4OS will load and you can begin using and enjoying it.


5. Uninstallation

Just launch the "q4os-winsetup.exe" installer once again and the Q4OS uninstall wizard starts. The uninstaller removes the Q4OS installation completely, so your computer will be reverted into its original status as before installation.
