Windows 10: I can't install Windows from USB drive

I'm trying to install Windows on a brand new gaming PC I've just built. I've used Google to see if I can find an answer and I came across this post on the Answers forum: https://answers.microsoft.com/en-us/windows/forum/all/we-couldnt-create-a-new-partition-or-locate-an/acdb1dae-01d9-44f7-846c-433e5addcfc2My problem is the accepted answer links to a YouTube video that doesn't work for me.I've tried typing in the commands and what have you but the drive names are different and I don't understand what it's telling me to do. Can someone help me install Windows? I didn't realise it'd be this diffi

Step By Step from vista:
From admin cmd prompt

2. select disk 1 (replace 1 with your usb drive)
3. clean
4. create partition primary

9. exit

Copy Windows Vista's DVD ROM content to the Flash Drive

xcopy d:\*.* /s/e/f e:\ (d being your vista cd and e being your usb stick)

And that's it, boot off your usb disk

 

Installing Windows 7 via USB flash drive!

USB drive doesnt show up, even after a format through windows (XP)

Any suggestions?

 

help. USB drive isn't assigned a drive letter.

Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.
