When I press F8 and then 'repair your computer' I get the option to log on as 7Enterprise or administrator, the administrator needs a password and the 7Enterprise doesn't but only gives me one recovery option and that's startup repair.
I downloaded windows 7 onto my external hard drive and tried to boot from it but its not doing that either I have changed the bios settings so that its the first option to boot from but still nothing. Now I know little to nothing about computers so if you can please go easy on me.
Thank you for any help you might be able to provide.
P.s I think the guy I bought it off must have knew the password but I have no way of getting in touch with him.
