Ok, so i started to use an older pc. Its not as good as my current but its still up to standards as far as hardware. Its about 2 to 3 years since i used it. It loads up and starts up, except it shows a repair screen. I think I can use a USB to reboot it but i cant find the right files online to reboot it with. Does anyone know what i need to install into the USB. Or do i need to buy one or something? Hope I explained this right. Also, since it is a pc i built myself I am hoping that this subreddit is ok to ask in.
