BIOS / boot order ​

You need to enter your PC's firmware (BIOS/UEFI) to set the USB drive as the first boot device so Windows Setup loads instead of the existing system.

1. Check firmware requirements ​

Windows 11 requires the following settings to be enabled before setup starts. Check these while you are already in firmware. Setup will refuse to continue if they are missing.

  • UEFI mode (not Legacy / CSM), required for Windows 11.
  • Secure Boot must be enabled. If currently disabled, enable it now.
  • TPM 2.0 must be present and enabled. Look for PTT (Intel), fTPM (AMD), or a dedicated TPM option in the BIOS security section.

If you cannot find these options or setup still reports a compatibility error, see Enabling TPM 2.0 for Windows 11 Installation.

Installing Windows 10?

TPM 2.0 and Secure Boot are not required for Windows 10. You can skip this section.

2. Open firmware settings ​

  1. Open Command Prompt or Terminal as administrator.

  2. Run:

    cmd
    shutdown /r /fw /t 0

    The PC restarts directly into firmware settings without needing to press a key during boot.

3. Choose the boot device ​

  1. Open the Boot menu or Boot Override list in firmware.
  2. Select the USB drive that contains your Windows installer.
  3. If two entries appear for the same USB, prefer the UEFI entry.

Next step ​

Save your settings and exit firmware. The PC will reboot from the USB. When the Windows installer loads, continue with Setup wizard.
