I have a laptop Acer, Aspire 4720Z series
A copy of Win7 was installed recently, but due to the operating system was not original, I got a message of Win 7 needs to be activated with 2 options activate or windows set up. I use to cancel it and every thing was working fine except the back ground of the desk top is Black. Yesterday my wife selected the wrong option and now every time I open the laptop, I am getting the message of "Missing operating System"
I have tried to install Win Vista original copy, the set up was processing for some time then I got this message:
Set up did not find any Hard disk drivers installed in you computer. Make sure any Hard disk drivers are powered on and properly connected to your computer, and that any disk - related Hardware configuration is correct. This may involve running a manufacture. Supplied diagnostic or set up program. Set up can not continue. To quit set up press F5
Any help will be appreciated
