Reboot and select proper boot device or insert boot media in selected

I have a geforce6100pm-m2, What could be the problem?

Either the boot drive has been deselected and you need to go into the bios and select the right one again or your harddrive has died and you need a new one.

Also make sure that the cables on your hardrive and motherboard are fully seated and haven't come a loose.

I would get in the BIOS and make sure the hard drive shows up either there (If SATA/IDE) or if your running in a RAID mode, go to that configuration via the POST HotKey. easymoney9 is right, make sure your cables are working.

So then if your drive does show up and your experiencing something like this, you may have a corrupted bootsector/MBR (if your lucky) and that can be fixed by the windows installation disc and booting into the repair mode
