NEED HELP! Windows Boot up not working

[Killahbite]

Hello im new to the world of PC’s and just finished my first build. I turned my PC on and loaded up the BIOS and everything ran 100% well and was going really well. I put the Windows Installer USB Drive in and started to boot up my system and run the installer. I then realized and the screen where you put in a “Windows 10 product Key” that I didn’t have a key at the time....so I turned off my pc. Got a key later on and when I turned my PC back on to do the who windows installer process again I now get a blue screen with the prompt “Something went wrong :( “ with the error code (0xc000021a). When the USB Drive tries to load the installer did I mess it up when turning off my computer and not finishing the Windows Installer? I can still boot from the USB but after I select “Windows setup(64-bit) it gives me the blue screen. Im just very lost on what to do next to fix the problem. Please help

make another USB windows installer, install again. Do not turn off the computer

okay amazing. This will fix the blue screen?

First boot your old system if you have any (and if it's win10) from old hdd/ssd. Just for test. Blue screen may be related to bad hardware.

seems as though something got messed up during the install/setup process.  It is faster just to start over instead of farting around blue screens and errors.  If it still does it after reinstalling, then you can look at other reasons for it failing to boot/load or whatever
