I have an HP Envy x360 - m6-aq103dx running Windows 10 (installed when I bought the machine).  About a week ago, I got an error after restarting with message:

 

Your PC ran into a problem and needs to restart.  We'll restart for you.

For more information about this issue and possible fixes, visit https://www.windows.com/stopcode

If you call a support person, give them this info: Stop code UNMOUNTABLE BOOT VOLUME

 

I let the machine run through the automatic repair options, but after running overnight, I only had a black screen.  Since I don't have the Windows 10 media, I went to the Microsoft site and made a USB of the Media Creation Tool.  I booted from this and got to the command prompt and followed the steps at this link https://www.technipages.com/windows-10-fix-unmountable-boot-volume-error. These included chkdsk and and trying to fix the master boot record.  All were unsuccessful. 

 

I am currently booting from USB and running a live version of Ubuntu 18.04.  I have been able to retrieve all of my files from the computer, so I don't have any issues if I need to wipe the hard drive and start over, but I'm hoping there is another fix. 

 

Any help will be greatly appreciated!  Thanks!

Will it start in safe mode with the USB drive?

Hi FreeBooter,

 

I have started working my way through the steps you have outlined.  For the first 4 steps, see attached for a screenshot of the results.  

 

For the command "wmic diskdrive get status", I got a status of OK from the system.

 

I am currently running the command "Chkdsk C: /r".  It has been running for about 24 hours now.  For Stage 1, there were 8 instances of "File record segment XXXXX is unreadable".  In Stage 2, there were many "Correcting error in index $XXX for file YYYYY" statements, along with several other entries.  The final statement from Stage 2 was:

16560 unindexed files scanned.

16555 unindexed files recovered to original directory

CHKDSK is recovering remaining unindexed files.

  5 unindexed files recovered to lost and found.

 

Stage 3 seemed to complete with no issues.  Stage 4 has many "Windows replaced bad clusters in file ..." statements.  This is the stage that is currently running.  The progress line says "98129 of 521968 done; Stage: 18%; Total: 36%; ETA:  38:01:58".  The ETA keeps jumping around between 20 hours and 40 hours.  

 

I will continue to monitor the machine and will post more when it finishes running this Chkdsk command.

 

Thanks for the help so far!

I thought it was taking too long as well.  When I got home from work tonight and checked, it had not changed status since last night.  I stopped chkdsk and rebooted without the USB and went into the System Diagnostics tool.  HP has HP PC Hardware Diagnostics UEFI loaded here.  The hard drive is a 1 TB, 7200 rpm ATA drive, model number HGST HTS721010A9E630.  I then ran the Hard Drive Quick Test and got the following output:

 

Testing Drive: 1

Hard Drive SMART Check: Passed

Hard Drive Short DST Check: Failed

Failure ID: RU0DWC-8GE94P-GXGK6K-60UD03

Product ID: W2K45UA#ABA

 

I then ran the Hard Drive Long DST Check to see if anything different occurred.  Here is the output of that test (which only took about 15 seconds):

 

Testing Drive: 1

Hard Drive Long DST Check: Failed

Failure ID: RU0DWC-8GE94P-GXGK6K-61CM03

Product ID: W2K45UA#ABA

I'm guessing that all of this means that a hard drive failure is imminent.  If that's the case, do you know how to replace a hard drive on this machine, or point me to a how-to manual/video?  Also, how do I reinstall Windows 10 once I get a new hard drive installed?

 

Thanks again for the help!

Not sure where you are in the world so a couple of example links for you here and here

 

HDD replacement guide here

 

Once you have fitted the drive you may need to disable secure boot in the BIOS in order to be able to boot from your USB device, if this is the case see canned info below;

 

 

While the computer is re-starting,you will need to continually tap or hold down the particular key that will allow you to access the BIOS on your computer, we will use the F2 key as an example here;

After restarting the computer, when the screen goes black, press and hold down the F2 key, wait for the BIOS to load.

Select Security -> Secure Boot and then Disabled.

Select Advanced -> System Configuration and then Boot Mode.

Change UEFI Boot to CSM Boot.

Save the changes and Exit the BIOS, commonly F10.

Thanks, phillpower.  The HDD replacement guide is very helpful and doesn't look too difficult.  I'm in the US, so I'll look for the same hard drive from a US vendor. 

 

One more question: I don't know where to find the Windows product key.  Will I need that to re-install Windows when I get the new HDD installed?

[dmccoy]

With Windows 10, once it is installed unless you make really major hardware changes you do not have to re-enter the key when reinstalling.

[slreagan]

Thanks, dmccoy.  The only hardware change I'll be making is to install a new hard drive.  I'll get that ordered and then try to reinstall Win10 once I've replaced the HDD.
