Prepare a Windows 11 ISO

Before you begin

Back up files that cannot be replaced, save the BitLocker recovery key when encryption is enabled, and prepare bootable Windows recovery media. Record the current firmware and boot settings. Connect reliable power and leave enough free space for Windows Setup and its rollback files.

Microsoft does not support Windows 11 installations on hardware that fails the minimum requirements and does not guarantee updates for those devices. A successful installation today is therefore not evidence that future feature or security updates will install.

Recommended workflow

1. Identify the generation. Use FlyOOBE 3 for its current review-oriented workflow; treat 2.4 and Flyby11 Classic as distinct legacy branches.
2. Collect a baseline. Record Windows edition, build, activation, TPM, Secure Boot, boot mode, storage health and driver status.
3. Review, do not batch-approve. Read each proposed action and skip anything you cannot explain or recover from.
4. Change one stage at a time. Reboot and validate networking, activation, Device Manager, Windows Security and recovery access.
5. Keep evidence. Save screenshots, Setup logs and the exact release name so troubleshooting matches the workflow used.

Decision and verification

Verify source, edition, language and architecture before installation. The correct result is not merely reaching the desktop. Verify that Windows starts twice, the expected edition is activated, critical devices have drivers, Windows Security opens, encryption state is understood, and WinRE remains accessible. If any check fails, stop and use the documented recovery path before applying more changes.
