I don't know why, but upon starting the computer, the "HP PC Hardware diagnostics uefi" shows up. I have try the memory test, which says that "memory quick check : passed". Then, I tried the hard drive check(quick check) , but it says "NOT INSTALLED". I also tried to exit a couple of times but it is always shows that "boot device not found". I don't know what to do now, so please help me as soon as you can.

Thank you.
