C Drive Not Recognized – How to Fix it?

When I started my computer after adding a memory into it but it didn't work, so I undo each and everything back to the previous state. Now, again when I started my computer it displayed a message O.S not found. Then I boot up my computer with the disk and typed ‘C:' in return it displayed a message C drive not recognized or ‘invalid drive'. So kindly help me! I just can't figure it out.

Well, as far as the hard drive is concerned, it is connected with the system properly, most probably. Well you need to go to the BIOS settings and confirm that hard drive detection is set to AUTO. And hopefully you didn't repartition your drive.
