Hello i am new here.. One day, my laptop just crashed and i went to a store that installs laptop. It turns out that the hardware was really bad so he replaced my hardware to a new one. He offered to install window 7 on my laptop for 50 bucks plus labor. Obviously that is a rip off so i thought that i could fix it myself somehow. I thought wrong. When i got home, i tried to turn it on but i keep on getting the message, Reboot and select proper boot device or insert boot media in selected boot device and press a key. i did press F12 but i was not able to boot. HELPPPPP. Is there a way i can get in my laptop without buying a CD? because my laptop doesn't have a cd drive. Help would be appreciated. THANKS!
