My laptop wanted to do 3 updates last night when I shut it down - don't know what updates - but after bout 30mins of doing nothing I turned the power off. It's now npt doing anything!! Power is on & initially got a Boot Menu box with info on but now the HDD/SSD info that was showing has disappeared. I'm a real non tech person so haven't a clue what's happened or how to sort it. Wasn't having any problems at all until the laptop tried to update last night. Can anyone help??
