Hi Rodolfo, What model of machine is this - and how new? How did you write the image to the USB stick? CSM is probably not needed. USB boot *should* work but there is a way of forcing boot only to Windows 11 in some machines. (I had this on a relatively new T490). Does it show any messages? > Rodolfo > All the very best, as ever, Andy Cater
