Help! Just installed my 1st hard drive...hooray! right? No so fast my techie friends. For I am rookie and need some help. My old hard drive crashed...took it to computer nerdz here in Austin...they handed me my old HD and 4 disk of "stuff" they were able to recover. I go to Fry's by a Seagate PATA/100 250G and bring it home and (with the help of some online YouTube guides) install it. Plug everything in power up and: "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key_" One site stated my "jumper" may be in the wrong place. I moved it from "Cable Select" to "Master" but still get the same message. I unplugged everything and started over making sure I was plugging it all in correctly (to the best of my limited knowledge) and am reasonably certain all is correct. Replace the cover, plug in and....same message. What do I need to do from here? This is a desktop, primarily used for email and pictures/videos of my children. HP pavilion a250n (sad, I know...budgets) about 4 years old. 2.6GHz, 512MB SDRAM Windows XP I'm sure I'm missing other info but any help would be greatly appreciated!!!
