This section contains the steps for a Clear Linux* OS manual installation. It picks up where the Install Clear Linux* OS on bare metal (automatic) left off.
To perform additional tasks during the Clear Linux OS Installer setup, select the < Manual(Advanced) > menu option (figure 1).
- Modify the disk layout using the cgdisk utility
- Add additional command-line parameters to the kernel
- Create a hostname for your system
- Create an administrative user
- Add additional software bundles to enhance the functionality of your initial Clear Linux OS installation
- Optionally set up a static IP address for your system
Begin the manual installation process
Move the cursor to the < Manual(Advanced) > menu item and press the Enter key.
Figure 1: Choose installation Type
The screen Choose partitioning method will appear (figure 2).
If your hard drive has already been partitioned for a Linux system, you can select the < Use default partition and mount scheme on target device > menu item and press Enter to move to the next step of the installer setup process.
Otherwise, to set up your hard drive partitions manually before moving to the next step, select the < Manually configure mounts and partitions > menu item and follow the instructions for using CGDISK to set up your Clear Linux hard drive.
Choose target device for installation
The Choose target device for installation menu, shown in figure 3, displays the current device and partition information. In this example, /dev/sda is the only drive on the system with three partitions defined and assigned. The menu cursor highlights the partition to install Clear Linux OS onto.
Select the < Partition /dev/sda > button and press the Enter key.
To return to the previous menu, press the Tab key to highlight the < Previous > button and press Enter to return to the previous menu.
Next, you will be presented with a warning screen (figure 4) with < No > highlighted by default. If this is the device onto which you wish to install Clear Linux OS, press Tab to highlight the < Yes > button.
Press Enter to proceed.
Additional manual installer settings
The next steps of the manual installer setup process allows you to:
- Set up any additional command-line parameters to the kernel.
- Create a hostname for your system.
- Set up an administrative user.
- Install additional software bundles.
- Optionally create a static IP address for your system.
The Append to kernel cmdline menu shown in figure 5 allows you to add more options to the kernel command-line to further customize your installation. Normally this is not required; however, if there are specific options that need to be set in the Linux kernel, you can enter them here. For a complete list of command-line parameters for the Linux kernel you can visit the official documentation of the latest kernel’s command-line parameters.
Add any additional command-line parameters in the Append to cmdline: field and then press the Tab key to move to the < Next > button and press Enter.
The Configuring Hostname menu shown in figure 6 suggests a hostname string prefaced with “clr”. You can make your hostname anything meaningful and unique. Once complete, press the Tab key to move to the < Next > button and press Enter.
Figure 6: Configure Hostname
To learn more about hostname naming conventions and restrictions, you can check this wiki page about hostnames.
The User configuration menu shown in figure 7 allows you to create a userid with administrative privileges. If you do not want to create a user at this time, select < No user creation (login as root) > to skip this step and proceed to the Bundle selector menu.
Figure 7: User configuration
To create a userid, select the < Create an administrative user > field and press Enter to go to the the next screen.
You will be presented with the second User configuration menu shown in figure 8. You are only required to fill in the Username, Password, and Confirm password fields.
To give a user administrative privileges, press Tab until cursor appears in the field Add user to the sudoers? and select. This adds the user to the wheel group and allows entry of the sudo command.
After entering all data, press Tab until < Next > is highlighted. Then press Enter.

In the menu Bundle selector (figure 9), you can add software bundles to your initial Clear Linux OS installation. Press the Tab key to highlight additional bundles, and then press Spacebar or Enter to select each bundle. This menu will also list the additional — required — software bundles that will be installed during the Clear Linux OS installation.
For a complete description of the content of these additional bundles, go to the software bundle list and select the name for a specific bundle to show the contents within the bundle.
Target system network configuration
Before the actual Clear Linux OS installation begins, we must set up the Network configuration shown in figure 10. Select < Use DHCP > to have an IP address automatically assigned when the system boots up.
You can optionally set up a static IP address for your system. Select the < Use static IP configuration > menu item and fill in the required fields.
The Clear Linux OS installer is now ready to use the information you provided on the previous sections to begin the actual installation. Figure 11 shows the installer’s prompt to begin the installation.
When you are satisfied with the information entered, select the < Yes > button and press Enter to begin installing Clear Linux OS.
The Clear Linux OS Installation begins and each step shows its status as it progresses through the manual installation process as shown in figure 12.
Once all steps have completed, you will see the Successful installation status message and the < Ok > button is highlighted as shown in figure 13. Press the Enter key to continue.
Congratulations! The installation completed successfully and the system will reboot. Figure 14 shows the installer’s final prompt. Press the Enter key and remove the USB media while the system restarts.
Once the system boots, the Gnome Desktop sign-in screen shown in figure 15 appears:
Click on the username you created, enter the password, and you will be logged into the system. The Gnome 3 desktop appears as shown in figure 16:
You have successfully installed Clear Linux OS on a bare metal system using the manual installation method.
