Install Windows 11 From External Hard Drive. This option is for users that want to create a bootable installation media (USB flash drive, DVD) or create a virtual machine (. If the external drive is properly set up with a bootable operating system, it should start up from there.
Access the boot menu or modify BIOS/UEFI to boot from USB.
In the new small window, click "Create installation media for another PC", and click "Next".
Download EaseUS Todo Backup and start with the system clone feature. Then choose language, edition, and click "Next". Select the correct USB flash drive from the list under Removable drives.
