Yesterday I made a post about my PC having a virus that wouldn't let me reset to factory settings or go to a restore point, so I was advised to boot off a USB drive that has only Windows 10 on it. So I installed Windows 10 off of Microsoft's media creation tool page on their website and completed the installation process. After it said it was finished installing, i unplugged the USB from the laptop i was installing it on and plugged it into the PC i was trying to reinstall windows on. I opened up the UEFI after plugging in the USB and changed it to the #1 boot option, but when i saved and exited, all I saw was a black screen with a blinking underscore. I made sure everything was right in the UEFI settings (as far as I know). I also tried looking up other solutions but none have seemed to match my issue. If anybody has a solution please reply.
