This is the first time I’ve ever come across this and spend ages seaching on the Asus forum. Most comments were re-burn the DVD etc etc. The problem I had is that I did not install a CD/DVD drive, so why was this error coming up.
I eventually found a resolution on the Technet forum. Many thanks to the original poster.
I assume all of you is using USB drive to install.
When Windows is asking for driver, just click Cancel. You will be brought back to the welcome screen. At the welcome screen, remove your USB drive, insert it back to DIFFERENT USB PORT. Click Install Now again. The installation process will be like usual.
This problem happened to all new version of updated Windows 7 installer. I think, it is due to failure of Windows installer to remain its detection to the USB drive. It lost the connection, and became confused, don’t know where to find the USB drive it used to read before.
When we re-insert the USB drive, Windows installer will detect the USB drive back, and continue like usual.
Good luck and cheers! TQ.
