I'm trying to install Windows 7 Ultimate Edition (Win7_Ult_SP1_English_x32.iso) on a newly wiped laptop using a bootable USB key I made with Rufus. However it's going straight from "Setup is starting..." to
"Load Driver
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.
Note: If the Windows installation media is in the CD/DVD drive, you can safely remove it for this step."
This laptop doesn't even physically have a CD/DVD drive; there is no disk tray! This is ridiculous! Help!
