Windows 7 or Vista installation goes as usual, except in some rare cases you can encounter the following error:
A required CD/DVD 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 drive, you can safely remove it for this step.
Screenshot of this error:
In this case please reboot, enter BIOS setup and put USB mass storage devices to USB-HDD boot mode. (USB-ZIP / Superfloppy / whatever else would cause this problem).
If it still doesn't work, here's another advice.
This problem happened to all new version of updated Windows 7 installer. This is probably because of the failure of Windows installer to retain 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.
