Technically feasible, the Windows installer ISO you download onto a USB stick can function as a genuine Windows setup, though the complete installation may encounter issues if the system drive is a SCSI device on a USB bus. This could trigger errors, but with modern UEFI support and Windows' evolving architecture, it should work smoothly. Prepare your USB by formatting it like a traditional hard drive and creating an EFI partition. Windows might not accept these changes, so you may need to switch to another OS. Once ready, manually install Windows onto the drive—obtain the necessary .esd/.wim files from a Windows installer ISO. Then add the bootloader to the EFI partition. Afterward, Windows will fully install and boot from the USB, allowing you to configure users and settings for your new system.
