Note: We don't recommend installing Qubes in a virtual machine! It will likely not work. Don't send emails asking about it. However, you can install it on an external USB hard drive and run from it, at least for testing (normally such disks are *orders* of magnitude slower than even the slowest internal hard drives).
See [this page](/doc/QubesDownloads/) for ISO downloads. Remember, we have absolutely no control over those servers, and so you should be assuming that they might be compromised, or just be serving a compromised ISOs because their operators decided so, for whatever reason. Always verify the digital signature on the downloaded ISO. See this [page](/doc/VerifyingSignatures/) for more info about how to download and verify our GPG keys, and then verify the downloaded ISO:
On windows you can use [Rufus](http://rufus.akeo.ie/) tool. Be sure to select "DD image" mode (you need to do that **after** selecting Qubes iso image):
Then, when finally ready, boot your system from the installer DVD and follow the instructions on screen. The installer is very simple and asks very few questions -- it's actually easier to install Qubes right now than most other Linux distributions!
The installer loads Xen right at the beginning, so chances are high that if you can see the installer's graphical screen, Qubes will work on your system :)

- Please do not write email to individual developers (Marek, Joanna, etc) asking questions about installation or other problems. Please send all such questions to the mailing list.
