Default boot device is missing or boot failed

Good evening,

I have a trouble with my other cumputer. Indeed, yesterday, it suddenly crashed and restart. It tried to do an update. After my pc power off, I, obviously, restart it.

However, after downloadind and running MediaCreationTool on my USB key, when I try to boot on my key on my unfunctionnal pc, it does not work. I still have this message.

Any helps would be really appreciated.

Thanks you in advance.

Best regards,

Aurélien

Default Boot Device Missing or Boot Failed.

I’m using a Acer Aspire v5-573PG Windows 10 version and whenever I turn on the laptop it shows

“Default Boot Device Missing or Boot Failed.

Insert Recovery Media and Hit any key

My laptop’s screen is all cracked up and the screen is opened up. Maybe that’s the problem..?
