  2. Hi,
    I created a bootable USB key with Rufus as indicated with the latest ISO of windows 11. When I wanted to install it, my PC refuses to start on it, yet I did the necessary in my UEFI BIOS. Could it be that I had to deactivate Secure Boot to create my key, and then reactivate it to do the install?

  3. Hello
