Hi my HDD failed in my R5 Alienware  PC 2016, Dell are replacing it under warranty all got so for.

This unit never came with a SSD so I bought one M2 256 fitted it all good.

I have complete a clean USB for window 10 with media tool now what do I do, how does the PC know that the USB is in the boot up.

Is there something I need to change in the boot menu.

I just don't want to make a mistake.

Thanks 

Dennis
