Windows 10: Upon starting my PC, I get an error message. Unable to Find Boot Device

I have already attempted multiple fixes and keep finding new errors that send me into rabbit holes.

- I have made a USB bootable drive for Windows 10 and run the automatic repair on the drive it returns an error code 00xc0000098

- I then attempted to restore the MBR with bootrec cmd manually, and it gives me an access denied message when running the /fixboot cmd.

- To get the access denied error getting out of my way, I ran the diskpart in the cmd prompt. I can see my hard disk via the disk part feature. However, there appears to be no partitions on the drive.

-Attempting to create a new partition gives me an uninitialized hard disk error.

My question is: Is the HDD dead or just that my data is now unrecoverable? I am completely lost on what to do next other than reinstall windows.

Unable to boot; 0xc000000f error on start

@axe0 - No, there was no file mentioned, although the error code remained the same. After I used the bootsec.exe /nt60 command the File: boot/bcd line appeared, which can be seen in the photos.
@zbook - I'll try what you have suggested and post the results. As for the assigned drive letters, no I don't know why they already have assigned letters. As far as I can recall, those were in fact the drive letters they were assigned when the computer was working, but I didn't reassign them during the troubleshooting process. The steps I had already taken are listed in the original post. I had tried to rebuild the BCD previously, but with the same results (i.e. didn't have access, system not found etc.)

Hi Don,

As you are unable to boot the device running Windows 10, provide us additional information to assist you better with this issue.

• What is the make and model of your device?
• What exactly do you mean by: "the laptop will not open"?

As a workaround I suggest you to unplug all the external devices connected to your computer, hard reboot the device and check with the status of this issue. Please be informed that there is a power supply to your device.

If the issue still persists, try the below troubleshooting steps as the boot files of current operating system might got corrupted.

I suggest you to download Windows 10 ISO file, create an installation media from other working computer to perform automatic repair of the computer that you are unable to boot.

Using ISO file to perform automatic repair will allow the device to boot the system to Windows Recovery Environment and tries to repair the device.

Step 1:
I suggest you to try automatic repairing the Windows and check if it helps.

Download the Windows 10 ISO and create a Media Creation tool and then perform Automatic Repair.

Refer to the following link: Installing Windows 10 using the media creation tool

(Refer to the section "Installing Windows 10 using the media creation tool” in the above article for creating the tool).

Step 2: After creating the tool perform an Automatic Repair.

I would like to inform that, if your Windows 10 is not able to boot or startup, Automatic Repair will come into action and try to diagnose and fix the issue. It will scan system files, registry settings, configuration settings and
more and try to fix the problem on its own, automatically.

Perform the Automatic repair:

• When your computer starts, wait for the manufacturer logo to check the option for boot menu, it will usually be
  F12.
• The boot menu key might differ with each manufacturer. If you are unable to find the boot menu key, you may refer the user manual.
• Restart the computer, when the manufacturer's logo is displayed, keep pressing the
  Boot menu option key to enter the boot menu and change the boot option to
  CD\DVD ROM.
• After you boot your computer using Windows 10 DVD, a black screen appears with gray text "Press any key to boot from CD or DVD". Press any key.
• Select the correct time and Keyboard type.
• Click Repair your computer in the lower left corner
