A detailed, illustrated guide to installing from the USB stick is available in our guide: Installing Windows 11 Pro from a USB stick – step-by-step guide 2026. A pure activation guide can be found at Windows 11 activation.
01
Plug in the USB stick and restart the PC.
02
Open the boot menu – usually with F12, F11, F9, or Esc – and select the USB stick as the boot device.
03
Run the setup – choose your language, start a clean install or upgrade, and follow the instructions.
04
Enter the product key and connect to the internet – activation happens automatically via the Microsoft servers.
Common activation issues and solutions
The PC does not boot from the USB stick
Check the boot order in the BIOS/UEFI and disable „Fast Boot“. Select the USB entry in UEFI mode, not Legacy mode.
Message „This PC can't run Windows 11“
In most cases TPM 2.0 or Secure Boot is missing. You can enable both in the BIOS/UEFI – depending on the manufacturer, TPM may also be called „PTT“ (Intel) or „fTPM“ (AMD).
The product key is not accepted
Enter the key exactly and without spaces, and make sure you have an active internet connection. If problems persist, our support team is happy to help.
Activation lost after a hardware change
Since activation is tied to the hardware, replacing essential components may require reactivation. Our service promise supports you in this case.
