I am trying to install Windows 7 Pro on an HP Pavillion a720n. I bought the Windows7 Pro disk and license off of Ebay. When I received it, it would not run on the computer. I contacted seller, and he said I need to clean hard disk in order to use it as it is meant for clean install into a new or newly built computer. I have been tryign for 3 days to get instructions for installing it, and keep running into problems. I was told by one tech to boot it from the disk player via the bios, but am stuck and cannot get that tech back into the chat we were on. I am using a different computer to be here.
I am totally confused and just need to get this hp computer running on Windows7 pro. Can anyone help me? We are retired and cannot afford to take it to have it done, nor do we have a vehicle to take it anywhere. ;-( I am now so frustrated I am in tears over this! Can anyone help me?
