**Note:** Be sure that you use a modern, non-handicapped browser to access the links below (e.g. disable the NoScript and the likes extensions that try to turn your Web Browser essentially into the 90's Mosaic).
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 :)
If you have Qubes Beta 3 currently installed on your system, you must reinstall from scratch, as we offer no direct upgrade option in the installer (sorry). However, we do offer tools for smooth migration of your AppVMs. In order to do that, please backup your AppVMs using the ```qvm-backup``` tool [as usual](/wiki/BackupRestore). Then, after you install Qubes 1.0 rc1, you can restore them using ```qvm-backup-restore``` tool. However, because we have changed the default template in RC1, you should tell qvm-back-restore about that by passing ```--replace-template``` option:
Installing updates is very easy and can be done using the "Update" button in the Qubes Manager. Alternatively it can also be done from command prompt -- see the following for more details:
- NVIDIA GPU will likely cause problems, especially if you use suspend-to-RAM. This mostly results from the general poor support for NVIDIA GPUs under Linux, which in turn is caused by the lack of open documentation for those GPUs. You might try to use the NVIDIA's proprietary driver (see the instructions [here](/wiki/InstallNvidiaDriver)), which apparently helps a lot.
- Installer might not support some USB keyboards (\#230). This seems to include all the Mac Book keyboards (most PC laptops have PS2 keyboards and are not affected).
- If you don't enable Composition (System Setting -\> Desktop -\> Enable desktop effects), which you really should do, then the KDE task bar might get somehow ugly (e.g. half of it might be black). This is some KDE bug that we don't plan to fix.
