Unmountable boot volume - Blue screen error

Hi,

When I recently tried to restart my computer, it restarted, but the lockscreen froze. I turned it off, then powered it back on again, and I received a message saying 'Your PC ran into a problem' with the stopcode: Unmountable boot volume. It then straight away heads to Preparing automatic repair, however, ut does not load; it is stuck on that screen. I have tried to fix my PC with multiple methods (except for the new windows installation because my laptop does not support CDs), such as using the command prompt  installing new bios, and just about all the options in the Advanced options. Previously, I did not know that this was a possibility so I have no restore points. The first question I have, is:

Is there any other way to fix this without having to reset my laptop?

If not, I am willing to reset my PC. However, the problem is, when automatic repair loads, it shows the 'choose your language screen' then proceeds to go to this screen:

When I click on the troubleshoot option, it leads me to this screen.

As you can see, there is no option to reset my PC, like there should be. Therefore, I cannot reset my even if I wanted to. My question is: How can i reset my PC if there is no reset option? 

I would really appreciate if you get back to me by the end of the month. Thank you in advance.

    Hi, I'm Robinson, an Independent Advisor and a Windows user like you.

    The error can be caused because of a boot corruption file.

    1-Create a USB device with an installation image.

    You can create using the media creation tool, download it on this link.

    https://www.microsoft.com/en-us/software-downlo...

    2-Enter on BIOS/UEFI and change to boot from the USB device.

    3-On installation screen click on "Repair your pc" on the left bottom

    4-Click on "Troubleshoot" then the Advanced Options page will appear.

    5-Click on "Command Prompt".

    6-Run these commands.

    chakdsk c: /r /f [Enter]

    bootrec.exe /fixboot [Enter]

    bootrec.exe /fixmbr [Enter]

    sfc /scannow [Enter]

    7- Reboot your pc

    The command is typed wrong don't have spaces between the dot on the bootrec.exe.

    Run the bootrec.exe command again and after finish run the SFC /scannow command again

    Sorry, I forgot one step, before run these commands do you need to identify the Windows partition. Normally are mounted under the letter D:

    1-When you open the Command prompt run command to change to another partition.

    2-Type D: and press enter then Type: dir and press enter

    3-If you are in the right place the dir command you return the folders, Windows, Program Files, Program Files(x86), Users

    4-If you don't receive this response return to step 2 and try another letter E:, F:...

    5-When you find the Windows partition run the commands:

    chkdsk c: /r /f [Enter] (This is the correct command, change the C: for the letter that you find before)

    bootrec.exe /fixboot Enter

    bootrec.exe /fixmbr [Enter] (This command will recreate the MBR table)

    sfc /scannow [Enter] (This command will repair all corrupt files on the Windows installation.

    Hi RobinsonSilvestre,

    I did what you said, and I changed the partition. The chkdsk command was able to run, but it said that it detected no problems with the computer and that no further action was needed. Nevertheless, I tried the bootrec. exe commands and they resulted in the same message I got from using them before. This was the message.

    Then I ran the sfc /scannow command however after the scan ended, it said that windows was not able to perform the requested action.

    Is it that my computer has a hardware problem and that some component needs to be replaced? (I initially disregarded this because my laptop is only two years old). Could you please get back to be on this?

    Hi RobinsonSilvestre,

    I followed the instructions you provided, but when i got to the command prompt and tried to run the commands you gave, for some reason, they would not work. When I ran the first command, the computer said the command was invalid. I then ran the command again, but this time with chkdsk instead of chakdsk; however, the computer said something along the lines of 'the command was RAW' and that it did not support 'RAW files'. Since the chkdsk command wouldn't work, I tried the other commands, but both of them resulted in a message that appeared barely a second after, that basically had information of what commands were supported. The only command that worked was the sfc /scannow command. Could you please explain what exactly the bootrec. exe commands are supposed to do, and what should appear on the screen after you run them? Also, I have read on a few websites that the chkdsk command sometimes doesn't work if your computer has a bootable drive letter other than c. I have never changed my bootable drive letter, but if my computer has a different bootable drive letter, how can I find out what it is? Images would be appreciated. (I have a HP pavilion x360, if that helps).

    Thanks in advance, 

    Ari
