Everything was fine a couple day ago when I used my laptop, but when I started it up in class today I got the black 'Boot Device Not Found' screen. I did a quick hard drive check from that screen, and this is what came up.



I even checked the boot sequence and that's still fine, and there's no USB devices plugged in whatsoever.

Boot your computer into BIOS setup utility to check if bootable device of the operating system detected BIOS.

How do I check if the HDD is detected in the BIOS?

 

My OS is on a flash drive, and after changing the boot sequence to the USB options, I still have the same Boot Device Not Found black screen.

If you can boot computer with Windows Setup Media and from Windows Recovery Environment we can check if Windows 10 detects your computer hard drive.

Are you sure Windows 10 installation USB drive works?

I'm 99% sure it's the same USB flash drive I used to put Windows 10 on it in the first place

If you set the USB device as first boot device then computer should boot from USB device.

If you have working computer you can make a new one with Windows 10 Media Creation Tool.

Okay, made the setup USB (all that went fine) and when I set my boot sequence nothing happened (still getting the Boot Device Not Found error screen). The USB has a little light on it, and that lit up just fine before it got to the error screen but yeah, no effect.  Here's my boot sequence btw;

F9 (Setup defaults) in the BIOS setup utility? Just tried that as well, with the same results.

Can you test the USB flash drive to see its bootable you can test it with Qemu Simple Boot tool.

Ran the Qemu tool (chose HDD as the "bootable media" and selected my flash drive) and the window popup stayed like this without changing. It's been an hour now, is it supposed to look different or is something wrong?

We know USB flash drive is bootable can you disable UEFI and enable Legacy BIOS firmware see if you can boot your computer with USB flash drive.

That allowed it to boot to the USB. I opened up command prompt and input the commands you listed, but I got an 'Access is denied' response when trying to use Bootrec /FixBoot



This is where I'm at right now.

Type Y letter at Bootrec /RebuildBcd command and restart your computer. Make sure to enable UEFI firmware to check if Windows 10 boots.
