HP Recommended
Product: Pavilion notebook k8y43av
Operating System: Microsoft Windows 10 (64-bit)
On booting my laptop displays the error "Boot device not found" "hard disk 1 - (3F1)". When I run system diagnostics hard drive check no hard drive is found and the error changes to "hard disk - (3F0)". When I bought the laptop I had a small solid state boot drive installed. I'm guessing that is what is referred to as 3F1 but I really don't know where that is or how I can check the connection. It isn't a removable drive I don't think. In any case disconnecting and reconnecting the main hard drive doesn't change anything. I've also tried removing all batteries to reboot the bios and that didn't fix anything.
When I hit F9 on boot up a new menu opens with the option Boot from EFI file, but when that is selected the error "no valid file system available" displays.

How do I check the connection on the ss boot drive?? Does it sound like that is the problem and how can I fix it? Do I need to reinstall an operating system entirely on the main hard drive?
