I have a computer I am trying to install operating system on but I have run out of ideas. It is a hp pavilion 10 touchsmart 10z-e000 notebook. First off the hard drive went bad so I replaced it with a new one. Well there is no cd drive which makes it hard to use a windows 7 cd and when I go to the boot option menu it displays no options such as usb, cd drive etc. I have a external cd drive but of course it cannot read it without installing drivers. I have run out of things to try and need help please. I am pretty decent with computers but this one has me.
