Can't boot to usb drive

[pelouk]

Need a bit of help.


I've been trying to get my laptop to boot to Linux 4.0 on a 4GB HP USB drive. I've changed the boot order (or at least I've tried to) to show the USB as number 1 position in the Boot section of the BIOS but the machine doesn't want to know and keeps booting up in Windows.


I don't know if it's relevant but my laptop is an Asus Vivobook 14_E406SAS.  Originally it was running Windows Home 10 S but I changed it back to the regular Windows 10.


I can't see where I'm going wrong but would be grateful for any advice.
