Creating an Installation Media for Intel Boards

This guide explains how to create a bootable media (e.g., a USB drive) to install Clea OS onto a storage device connected to an Intel-based board. Supported storage media include eMMC, SATA drives, and other compatible storage solutions.

• The first step in installing Clea OS on an Intel board is to download the appropriate image from the latest release available on the Donwloand Link page. In the Intel section, the relevant files to download are those with the wic.bz2 and wic.bmap extensions, as these are required to flash the image onto the installation media.

• Once you have downloaded the necessary files, you can create the bootable media by flashing the image with bmap-tools, as described in the Installation on an External Storage page.

• After creating the installation media, insert it into the Intel board and power it on.

• Enter the BIOS to select the installation media as the boot device by adjusting the boot order. When the board starts, you can interrupt the boot process by pressing ESC to enter into the BIOS menu:

  

• Navigate the tabs reaching the Boot menu. Then, move through the lines to find the boot order priorities:

  

• Place the selector in the Boot Option #1 and press Enter to select the installation media created as highest boot priority device:

  

• Confirm the selection pressing Enter and the updated boot priority will be displayed in the menu:

  

• Navigate to Save & Exit menu and select Save Changes and Exit. Reboot the board.

• After the board rebooted GRUB is loaded and it's menu will look like:

  

• Select install to start the installation procedure and press Enter. A script is launched, searching for available target devices for installation. A list of suitable storage devices will be displayed, and the user will be prompted to select a target device. For example:

  /dev/mmcblk1
  UEVENT=DRIVER=mmcblk
  MMC_TYPE=MMC
  MMC_NAME=DG4032
  MODALIAS=mmc:block
  
  Please select an install target or press n to exit ( mmcblk1 ):

  Here the only suitable target device is mmcblk1. If more devices are available they will be all listed in the same way as mmcblk1. The users selects the target device typing one of the strings between the round brackets.

• The installation script then replicate the OS on the selected device. It's possible that the installation script asks to the user a confirmation to erase the content of the device if a partition table is found in the target device.

• When the installation is completed, remove the installtion media and reboot the board.
