Hello, when I start my Windows 10 laptop, I get an error message that says:
reboot and select proper boot device or insert boot media in selected boot device and press a key
I hope you can help me because right now I can't do anything else.

Hi,

This question and error on computer startup comes up often.
I invite you to read this answer: https://forums.commentcamarche.net/forum/affich-35414302-boot-device-not-found#1
It is comprehensive.

~~

Since a working computer is available: Use Media Creation on a valid computer to create an installation USB drive: https://www.microsoft.com/fr-fr/software-download/windows10ISO
  • Boot from it by changing the boot sequence and indicating the USB drive or DVD: How to boot the computer from USB drive
  • You will arrive at the Windows setup program.
  • Go to repair your computer (menu at the bottom left of the main page)
  • Advanced troubleshooting options
  • Command prompt
  • type diskpart and hit enter

Give the results of the following commands:

list disk
sel disk 0
list partition
list volume
exit


Take a photo of the results and provide the results in a screenshot.

And give the result of the command:
bcdedit /v


Take a photo of the results and provide the results in a screenshot.

However, the bcdedit command doesn't work.
