As my laptop was functioning very slow I wiped it and after that I tried to install Windows 7 but as soon as I select Language, Time, Keyboard and click on Install Now, I get an error message as follow
"A required CD/DVD drive 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 CD/DVD drive, you can safely remove it for this step."
I can't understand what the error is about and I even tried to change bios setting from ide to ahci but didn't find the option.
What could be the solution for this please help.
