seems like either the hdd is disconected or the bootsector got screwed. err..can someone simplify the step-by-step oh how to check hdd on bios?
either way, i dont know if you could understand these things im about to say, but here goes.
first try going in to bios(google how to go into bios) to check if the HDD is still detected by the laptop. if not then open the laptop back panel where the HDD is and check the connection it might be loose or something.
if the HDD is still detected then it migh be the bootsector is coruptted because laptop is shutdown unproperly.
to fix the bootsec you'll be needing
1. a windows (im asuming you use Win 7) install or repair disk or bootable thumbdrive
2. a working dvd-rom if you're using instal disk.
step-by-step goes like this (assuming you're using win7):
1. Boot with the Windows 7 installation disc (google for how to boot from windows disk)
2. Follow the installation wizard until you see Repair your computer option, click it.
3. Click the operating system that you want to repair, and then click Next.
4. In the System Recovery Options window, click Command Prompt.
4a. If you haven’t checked the drive already for errors, type chkdsk /r.
5. Type Bootrec /fixmbr to repair the Master Boot Record .
6. Type Bootrec /fixboot to repair the Boot sector.
6a. (optional) if still persist you might need to rebuild bcd. Typle Bootrec /rebuildmbr
7. Type Exit and then click restart.
i hope these little hiccup make this 14 year old become interested in pc lol
