i want to install windows seven to my laptop and i don't have and extra disk. if i install seven over vista, will my files be deleted or will it still be there? or do i need to move my files to another disk? and install seven? sorry if this was a simple question, i'm just want to be sure about what i'll be doing. real life don't have save points. EDIT: ahh, thanks omgdaniel and Originality for clarifying some things. i won't be installing it immediately though(still downloading parts and school wifi is slow) so if any of you still have useful info i ask you to tell me please.
