Download and Burn the Install DVD

To download the installation disk, click here for latest release.

There are also links to checksums for file verification.

Download the File

It may take between 10 minutes and 4 hours depending on the speed of your connection.

Verify the File (Optional)

You can check that the file downloaded correctly using a md5 checksum program. This step is optional but recommended. Most Linux distributions come with md5sum, a checksum program already. Otherwise, you can download the program from several online sources and use it as outlined below.

  1. In a terminal, enter the following, replacing [path/to/file] with the path to the downloaded .ISO file.
    $ md5sum [path/to/file]
  2. The string you get from this command will look something like this:
    56b7sab208gb4de5250948a1856ddd0e [filename]
  3. Compare the string to the string in the checksum file on the download server. If it matches, the integrity and quality of the downloaded file is verified and you can burn it to a DVD.

If you are using Windows for download:

  1. Download winMd5Sum. Otherwise, you can download the program from several online sources and use it as outlined below.
  2. Install it by double-clicking the .exe file.
  3. Click on Start > Programs > winMd5Sum > winMd5Sum.
  4. Click the ... button beside the File Name box.
  5. Find the downloaded .zip or .iso file that you want to check, and open it.
  6. Get the appropriate .zip or .iso checksum from the Userful's download page, then copy and paste it into the Compare box.
  7. Click the Compare button. A download was successful if the checksums match. If they differ, you will need to download the file again.


To install, simply configure the system to boot from the optical drive, insert the .iso, and reboot the computer. Follow the prompts to install. When installation is finished, reboot the computer.

Firstboot Configuration

A customized installer will guide you through firstboot configuration. This includes accepting the license agreement, setting a root password, assigning a system hostname, creating a user and setting the time/date. Some guidelines for firstboot configuration:

  • The hostname you create should contain only alpha-numeric characters and hyphens (-). Other characters -- including a period/dot (.) -- are not supported by the network station driver. For example, test-computer is a valid hostname, but is not.
  • During the default firstboot configuration, you are required to create a user. If desired, several users can be created at this step by clicking on “Advanced”.

Note: Don't give localhost as the hostname.

External Packages

VW Install Third Party.png

All the CentOS-provided software packages that come with a base Userful install are free and open source and can be redistributed under various open-source licensing schemes. However, several essential packages (such as media codecs, Adobe Flash and Reader, etc.) cannot be redistributed freely and must be downloaded and installed from proprietary repositories.

Userful has provided a convenient method for installing these packages through the "Third-party Add-ons" feature inside of the Control Center. You can access the Control Center from System > Administration > Control Center . Once the Control Center has been launched you can move your mouse over System Operations > Third party Add-ons which will expand the menu and display the link to Install/Uninstall Third-party Add-ons.
Simply, select the package and hit "Apply" to start the installation process. No reboot required after completion.

Getting Updates

It is recommended to alwayscheck for updates after you install the product, to do so simply open the Control Center and you will see a notification if updates are available (and host PC is connected to the Internet).
