The Q4OS team has introduced a new way of installing the lightweight Q4OS distribution on computers which run Microsoft Windows. Since partitioning a hard drive and installing a new operating system can be a daunting task for new users, the Q4OS developers are making it possible to dual boot Windows with Q4OS without any partitioning required. "We are happy to introduce a first stable release of the Q4OS for Windows 10 installer. It allows everyone to install Q4OS alongside Windows in an easy way, with no need of modifying an existing Windows operating system, nor any of software installed, even with no need of repartitioning your disk drive. Simply download and run Q4OS installer, just like any other Windows application, and follow the installer instructions. The installer will install and configure your computer to be able to run Q4OS or Windows 10 in a dual boot mode. Once you perform the setup, you will be able to switch back and forth between Windows and Q4OS each time you restart your computer. This installer is compatible with Windows 10, as well as the 7 and 8 versions, and it's able to use Secure Boot, if available in the PC firmware. Secure Boot will allow you to boot Q4OS in a smooth and safe way." The Q4OS installer is able to install its operating system on the existing Windows partition by using a large loopback file which contains the Q4OS distribution.
