The subject basically says it all. I've searched with Google and have not turned anything up.
The system is a Latitude e6520 refurb I bought online. I have been in discussion with the seller and have sent it to them once to inspect and they installed a new hard drive. It is running Windows 7 (ultimate) and has the most recent BIOS update A19.
It will consistently not find the drive when issuing the restart command from Windows; I get an error "no boot device found" if I allow it to run past the initial boot screen. When I enter the diagnostics menu, I get a similar drive not found error message.
The work around is a cold boot and while that seems to be fine, I know this isn't normal and it concerns me. Has anyone else experienced this?
