7.3. Installing a bootable ISO to a medium and booting it

Install the bootable ISO image you created by using RHEL image builder on a bare metal system.

Prerequisites

You created the bootable ISO image by using RHEL image builder.
You have downloaded the bootable ISO image.
You installed the dd tool.
You have a USB flash drive with enough capacity for the ISO image. The required size varies depending on the packages you selected in your blueprint, but the minimum size is 8 GB.

Procedure

Write the bootable ISO image directly to the USB drive using the dd tool. For example:
```
dd if=installer.iso of=/dev/sdX
```
Where installer.iso is the ISO image file name and /dev/sdX is your USB flash drive device path.
Insert the flash drive into a USB port of the computer you want to boot.
Boot the ISO image from the USB flash drive.
When the installation environment starts, you might need to complete the installation manually, similarly to the default Red Hat Enterprise Linux installation.
