Hello I bought student win7 offer from digital river. Downloaded it to my mom's computer, extracted the file. Copied those files to CD...put in in my laptop, set to boot from CD but it does not start the install. It goes to Linux boot....I want to erase linux and install the window 7. Is the student download a full version or did I not make CD correct? After I extracted files I did not see any ISO file, so Just did straight copy to CD. Thank you for any and all Help.
