Windows 7 can be purchased online and downloaded. From the downloaded files you can create a bootable DVD. Three files are downloaded: An executable 64-bit Windows file and two .box files. Move all files to a new folder "w7p" and put the folder on the C drive. You have to download a Premastering file from here: http://depositfiles.com/files/d8zxuifur and paste it into system32 folder. Unpack .box files and click on "expanded set-up folder". Go to command prompt, enter large chunk of code (written below video for user to copy and paste)to create an image file. When image file is 100% completed find it in the C folder, you can burn it to DVD with Windows DVD burner, or use a free image burning program.
