The other day I was encountering a peculiar problem during my Windows 7 install on a brand new Crucial RealSSD C300 64GB. I got the error ”CD/DVD Drivers Missing” and it prompted me for a disk before I could even select the drive to install to. Google didn’t help much as the only answers were people posting “reburn the cd”, while I was installing from USB.
The solution is of course quite simple: Pull the USB stick when you see that message, then put it back in. Hit OK or whatever and that will dump you back to the main Win7 Install screen, now it will work fine. This is because the USB drivers reinitialize on some motherboards after the setup boots up and you have to re-plug devices to get them to redetect at that point.
Hope this helps someone.
