The live desktop beta image allows you to boot Clear Linux* OS into a GNOME desktop without modifying the host system. Using the live image, you can explore the possibilities of developing with Clear Linux OS.

You can also launch the installer to install Clear Linux OS on your target system. If you proceed with installation, this document assumes you follow the Recommended options.

Preliminary steps

  1. Navigate to the image directory.

  3. Open the system BIOS setup menu by pressing the F2 key.

    Note

    Your BIOS setup menu entry point may vary.

  4. In the setup menu, enable the UEFI boot and set the USB drive as the first option in the device boot order.

  5. Save these settings and exit.

  6. Reboot the target system.

Launch the installer

  1. After the Clear Linux OS live desktop image boots, select the Activities menu in the upper left.

  2. Select the icon, Install Clear Linux OS, shown in Figure 1.

    Select Installation Media

    Figure 7: Select Installation Media

Safe Installation

Use this method to safely install Clear Linux OS on media with available space, or alongside existing partitions, and accept the recommended partitioning schema. If an unallocated partition exists with enough space, safe installation is allowed.

If a warning message appears that no media or space is available:

  • Verify that target media has enough unallocated disk space
  • Confirm target media is properly connected or mounted
  • Review the size of existing partitions on the target media:
    • Linux* OS: lsblk -a
    • Windows* OS: diskpart, then list disk
    • macOS* platform: diskutil list

Destructive Installation

Use this method to destroy the contents of the target device, install Clear Linux OS, and accept the recommended partitioning schema. If no safe options exist, Destructive Installation will appear by default.

Note

From the Select Installation Media menu, select Enable Encryption to encrypt the root filesystem for either option above. See also Disk encryption for more information.

Partition minimum requirements

To add partitions manually, see Advanced configuration below and create partitions per requirements in Table 1.
