I popped in my Windows disc into my external DVD drive, installation started without a hitch, Windows told me I need the driver for the external DVD drive that the Window disc is running on in order to continue to install Windows. So I canceled the installation, shut off the laptop, got the driver on a USB stick ready and booted up my laptop ready to install Windows again. However this time around, my laptop would not read/boot from the disc no matter what. I made sure the boot order was changed in the Bios. Any idea how I could fix this? Thank you.
