Someone please help, I am a total retard. I got this laptop (well most of it) but it didn't have a hard drive. I got it free so no jokes.... Anyway I went and bought a hard drive for it, Seagate ATA 20Gb, and put it in. The guy at the store obviously lied, but I can't take it back because I bought it in NY on vacation, and I live in KY. HE said all I had to do was plug it in and it would work. Well I put it in and all my laptop would do is keep saying "no boot sector on hard disk". Can anyone pleae help me, keep in mind I am a total ***** to this, I thought I had to atleast get dos or something on it before installing an OS. It is an older laptop, Dell Latitude CPt but has good memory, and a basic processor. Not bad for free I guess, but what do I need to do to make "no boot sector on hard disk" go away?
