I have a Lenovo P500 laptop which was working fine for years. I never faced any issues with it so far until today. The screen suddenly froze and after a while when I tried to restart, a black screen showed up with a message ‘checking media’, and then it led to a blue screen that says ‘Default Boot Device Missing or Boot Failed’. It shows some instructions like using Recovery Media, choose a new Boot Device, or to boot Recovery Media, but in Boot Manager, I’m greeted with two more errors I believe.

  1. EFI Network 0 for IPv4 (B8-88E3-8F-4D-B3)
  2. EFI Network 0 for IPv6 (B8-88E3-8F-4D-B3)

What should I do?
