I just finished a new build with an ASUS Prime z270-a mobo and I can't get it to boot off my USB drive to install windows. No errors just booting into BIOS every restart. I've been tweaking with settings for over an hour and can't figure it out. I've tried two different USB ports on the mobo and I'm 99% sure I just have the wrong BIOS settings. Here are some pictures of my BIOS if anyone wants to take a crack. Thanks!

It does sound likely that the USB installer wasn't prepared correctly. There's a way to do it manually but using the tool makes it easier.

https://www.microsoft.com/en-us/software-download/home

The windows 10 tool from there will run without asking for a key first and automatically give you the most up to date version. When the option is presented, just choose to prepare a USB drive.
 


I might try it... when/if needed :)

I can’t open the pictures but it’s ok. When you land in your BIOS open up your boot menu. Scroll down and you should see a list of storage devices offering you the option to override the boot process into the drive you select. If you see your USB drive then click on it.

If not, navigate to your CSM settings and make sure they’re enabled.

Thanks for the responses guys. I used that program to load the ISO image onto the USB so I don't think that's the step for me.

@Jwpanz - I tried to show that in the pictures (I think you can only have one window open at a time to view them). My USB drive shows twice on the boot list once as a UEFI and once as a sandisk USB. I've tried both of them as the primary boot drive and it still won't load.
