I just bought a HP pavilion g7. It has unubnta linx 16.04.1 os on it and I hate it. I was wondering how to factory reset my laptop & put windows 8 back on it. Windows 8 is the factory os for it. I don't have a windows disk but I do have a usb drive. I just don't know how to put windows on it and get it to install on my laptop. I'm not very technanically inclined but I do know a few things. Any help to get my new laptop running as I would like and as it should be would be amaizing. Thanks!!
