Windows 7 install problem

I really hope you can help me because I’m tearing my hair out! I had a hd fail so invested in a sad. I wanted to reinstall win 7 because I’m used to it and like it. I have an official DVD so started the install, but I got a message saying there was a missing driver.
I’ve searched the net for an answer, watched numerous YouTube videos, but they talk about booting from a USB. I certainly didn’t encounter this last time I did an install, but that was within XP.
Can you help?
