Starting the Install

Now that you have downloaded your ClearOS ISO you can begin the install.

Boot

DVD or CD-ROM Installs

For optical disk-based installs of ClearOS, you will need to burn a CD or DVD of ClearOS. If you are using ClearOS 6.7 or later you will need to use a DVD drive to install ClearOS or use a USB install. If you ONLY have a CD drive and USB is not an option, you will want to download ClearOS 6.6 or earlier and run the updates immediately after your install by dropping to a command prompt from the console (Ctrl+Alt+F2), logging in as root, running updates (yum update) and then rebooting the server (reboot).

To burn the ISO image to a CD or DVD, you will need blank media capable of storing the size of the ISO image. You cannot copy the ISO image to the CD or DVD as a file, it must be burned using the ISO burn process. You can then boot this CD-ROM to start the ClearOS install. You may need to enter BIOS or hit a special key to boot from the CD or DVD. Pay attention to the screen during boot since the boot key options are often displayed for a short period of time.

To burn the ISO image to a disk, please reference this guide which will help you with the process. If you are having trouble finding the correct key to enter BIOS or boot mode, please refer to your hardware vendor's documentation for details. Alternatively, you can do what most administrators do: hit all the function keys, delete key and random other keys while cursing about why BIOS is still around.

USB Installs

If you are using a ClearOS 6.6 or later ISO image, you can place that image directly on a USB and boot off of the USB installer. This process is fairly straight forward. You can use this guide to transfer your ISO image to USB and install ClearOS. Be sure to check with your BIOS of your server to make sure that you have an option to boot from USB or that you can select boot media at the power on self test (POST.)

If you are using an older ISO (ClearOS 6.5 or earlier) and you want to use a USB method to install, you can reference this guide which allows you to turn your USB into a mini-OS that happens to have an installer on it.

Virtual Machines

Most virtual machine environments can boot directly from an ISO image. Please see your virtual machine documentation for details. If you are just evaluating ClearOS in a personal environment, we recommend the following minimum requirements:

  • Memory: 1 GB
  • Hard disk: 5 GB
  • USB and audio are not required

If you plan to run ClearOS in a virtual machine in a production environment, please review the system requirements.

Boot Screen

Once your system has passed all the usual hardware checks, you should see the installer screen shown below. If you are using a virtual machine environment, you should select the small screen / 800×600 mode to avoid annoying scrollbars in the install wizard.

Next Steps

Your ClearOS install is now under way and the next step is going through the installation wizard.
