USB Driver problems switching from Windows 10 to Win 7 on my Acer Aspire ES1-33

I get this error when I try to boot Win7 from a USB:

 

"A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now."


I tried using the USB 2.0 slot too. Any ideas how to resolve this? 

 

Also one of the solutions I found on Google asks me to the download "current USB 3.0 drivers for your Intel NUC". How do I find these? 

Thanks!
