I've had my Compaq Presario 700 series laptop, model 712ea for about 2 years now and up until 3-4months ago it ran smoothly. Now whenever I try to boot up the laptop I get a message from the BIOS informing me that there is no operating system found.
I've tried everything I can think of to remedy this issue, including reformatting the hard drive, running killdisk, installing various operating systems including Windows XP, Windows 98, Red Hat Linux. All with no luck. For a short time after I installed any of the aforementioned OS's the laptop would work fine but inevitably soon rather than later upon boot up the same message, "Operating System Not Found", was staring back at me.
Is their anything I can do to get the laptop to run again short of hardware replacement? If not and the only solution to the problem is through hardware replacement I would greatly appreciate some guidance as to where to look. Thanks in advance
