How do i reinstall my windows 7? -

I installed Windows 7 with no cd and no memory stick.. and i tried to install mirrors edge and tried to open a file with Notepad, not every program on Windows 7 OS wants to open with notepad.. and even avast anti-virus wants to open with notepad.. i would like to reinstall, or remove windows 7

First off, as Jason pointed out, you need to burn the ISO. I recommend taking a look at the installation instructions provided by Microsoft, as well as the FAQ page before you go ahead with the install. Here are links to both of those sites. http://www.microsoft.com/windows/windows... http://www.microsoft.com/windows/windows... Cheers, Jeff Windows Outreach Team

Download the ISO, burn it, then boot to it and reinstall.
