ChaletOS is an open source and completely free computer operating system that provides users with a unique style similar with the one of the Microsoft Windows 7 or Vista. It is derived from the popular Xubuntu distribution, anofficial Ubuntu flavor that uses the Xfce desktop environment.
Distributed as 32-bit and 64-bit Live DVDs

The distribution is available for download as Live DVD ISO images or approximately 1.5 GB in size each, designed for 32-bit or 64-bit computer platforms. The ISO images are hybrid, so you can write them on either DVD discs or USB thumb drives or 2GB or higher capacity, which can be later used to boot the operating system from the BIOS of a computer.

Offers advanced boot options

Among the boot options of the Live DVDs, we can mention the ability to start the live system with normal configuration, with ACPI disabled, with LAPIC and ACPI disabled, with enhanced disk drive support or in safe graphics mode. You can also start the installation directly (not recommended).
Minimum system requirements for ChaletOS

The developers recommend installing the ChaletOS distribution on a computer with an 1GHz or higher processor, at least 256 MiB of RAM (512MiB recommended), at least 8 GB free disk space, and a monitor/video card capable of 1024x768 resolution.
