I got in a HP DV7-1245DX today with the error code: 03F0 which then says "No boot device present, Install operating system".
This system was apperantly running normally, and then was going slow so the user reset it and started getting that error.
I thought this was a dying drive or corrupt boot sector but this code continued when the hard drive had been removed, and the system would find no other boot devices. I tried bootable cd's, dvd's and a bootable USB stick that I know works, and the system does not see any.
The odd thing is it CAN run a disk scan on the hard drive when its plugged in. It just does not see it in the boot manager. The boot manager is actually blank, showing no options for devices. I setup the boot order properly, and made sure "cd drive" was enabled as a boot device, but this changed nothing. I tried bios defaults also.
I removed the memory, tested each individually, unplugged the power and cmos and put everything back in, plugged in another hard drive with a different windows install, nothing changes the error.
I put the original hard drive in an enclosure and ran a MBR rebuild on it with EASEUS, and a disk scan which returned no errors, the system still could not boot to the device.
The only thing I can think at this point is that the disk controller went bad. Any other thoughts?
I have tried multiple motherboard repair services around the country for previous laptops with motherboard issues, but never found a reliable one (usually get them back to die a few days later) so if this is a disk controller issue this system gets sold for parts.
