Windows 10: Boot Device Not Found

Hi everyone,

Device : HP envy j170nf

Let me put you on my situation, my laptop run windows 10, I tried to install dual boot CentOS 8, over a network. I had to enable legacy support, I proceed the installation, and I think ,by a step, I damaged my boot section. I can't access windows anymore, and Linux can be accessed only if the legacy support is enabled. and when I access the Boot manager with legacy support enabled I see two options : Notebook hard drive and EFI file, ps : the EFI file is empty . And when I enter Boot Manger while legacy support is disabled, the boot manager is empty, and Boot device not found message appears. even when I connect a Bootable windows 10 usb, the boot manager still empty . So I decided to format my hard drive, I had to enable legacy support again and I delete all partitions I had the problem when selecting my disk : The windows cannot boot from this disk ... so I opened Commad prompt and I proceed with Diskpart clean - create partition primary - Format - active - assign , and i could select the disk then. I completed the installation, thinking that the problems are all solved, but when I disable legacy boot the same things happen. I thought that the problem is due to my hard drive, so I put another one, but the situation still the same, and when I try my hard drive on another laptop everything is good. so I said the problem is due to BIOS, I flash it with a bootable USB, burt nothing changes ! I tried the bootrec commands the problem still exist. What should I do ? help me plz !

Resume : with legacy boot enabled the boot manager isn't empty. but when it is disabled nothing appears even a bootable usb, and I get again the Boot device Not found.

THANKS IN ADVANCE

:)

No boot device found.

Please advise

I am unable to access the Internet on the experience on M531R – 5535 Dell laptop the error message that is being shown on the laptop is no boot device found press in a key to reboot the machine I do not have a USB nor do I have a boot disk.

Is it likely that I am able to use my mobile device to fix the laptop I’m just searching for any suggestions

 

Boot device not found

My computer froze. When I tried to restart a screen came up "Boot device not found. Please install operating system on your hard disk (3FO)."

I have tried reinstalling windows with a media creation tool. But when I get to the part about drivers it does not list drivers.

What do I do?
