Driver Issue while Installation with Pendrive

 This is the solution. 

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.
