I tried to install windows 7 and 10 on the hp notebook - 14-ac114na and the installation was interrupted as i formatted the disks and then cancelled the process, ever since then when i try to install a new copy of windows it says that a required CD/DVD driver is missing and then the installation won't continue until I locate said driver. I have tried everything out there and it still isnt working, i have tried usb, cd and tried to switch usb ports nothing is working any ideas??
