reinstalling Windows 10

[evenst3ph3n]

Hi I am trying to reinstall windows 10 from my retail USB. I have disconnected the ssd's and the hdd  from the motherboard by taking the SATA cables out of the drives themselves and keeping the cables connected to the motherboard. I am trying to reinstall to my M.2 drive which I did in January with no problems at all. I have recently had a problem with command prompt popping up and kicking me out of my games so I decided to do a reinstall. I pressed f12, and in the boot menu chose the USB with Windows 10 to boot from. Unfortunately it just goes through to my normal desktop and doesn't give me an option to reinstall. I am using a Z170 motherboard and fast boot is disabled. What am I doing wrong.

did you make your USB bootable?

Its a retail version I purchased and didn't have to do anything in January to make it bootable.

Well, it's super simple to download the files again from microsoft's official website and make it bootable yourself. Not including the downloadtime, it will take you 5 minutes to do yourself.

Why would I do that when I have a copy. Do you think there might be something wrong with my retail version?
