Planning on doing a fresh install of windows 7 ultimate 64bit on my asus pc, not actually sure what model it is because previous owner put it in an aftermarket case, i boot from windows 7 ultimate disc and it goes thru first few stages fine, when i comes to selecting the drive i get a window pop up saying 'A required CD/DVD drive device is missing. If you have a driver
floppy disk, CD, DVD or USB flash drive please insert it now.'
can anyone shed some light as to what driver it could be on about??
thank you in advance
