It seems to be an old topic. But I'm a newbie, and after reading the articles on this site I still don't quite understand. Also, I don't have a WINDOWSXP installation disc, so I have to be careful about everything. So I'd like to ask for a method that is safe, simple, and suitable for someone like me. Also, my computer doesn't have a floppy drive, only a USB flash drive. I hope an expert can give me some advice. Little brother offers his respects in advance!
