I am trying to reinstall windows 7 premium from the installation CD i got with my laptop, my hard drive died so i purchsed a new one yesterday, its not detecting the vd drive so i had to make a usb flash drive with the isntallation on. it detects it but keeps telling me it cant find drivers and i need to install cd/dvd to the drive, tried this but as before not detecting i have also tried the drivers on a usb stick also not detected and a more upto date installation with added p to date drivers but the message still pops up. oh external drive didn't work either
