5. Boot from the USB Drive
After creating the bootable USB drive, insert it into the target computer and restart the machine. Enter the BIOS or UEFI settings and change the boot order to prioritize the USB drive. Save the changes and reboot. The system will now boot from the USB drive, launching the CentOS 9 installer.
