Boot Device Not found - Hard Disk (3F0) Error

[Lesly717]

Hi, I’m experiencing difficulties trying to boot up my computer. Every time I try to boot up my computer I get an “Boot device not found” or “Please install an operating system”. I have tried to look for the problem in The hardware diagnostics test to see if my hard drives or anything failed to work, but everything passed its test. I have also tried to do a Individual hard drive quick Check, but It says “No hard drive installed. Please check that the power and data cables are connected properly”.  I have no idea what to do, Please Help !!

I am having same problem and was wondering the windows update that occurred shortly before this was the cause?
