I have the All in one sony vaio fit 21. I want to make an image of the windows incase of disaster. I don't want to go back to factory. However I cannot get anything to boot from the usb even if I try going through the bios or the assist button boot on usb.

I tried AOEMI PE Boot disk on usb. Is there a recommended way I can achieve this? I select the UEFI boot. I've also tried creating the legacy boot usb and none works.
