UNMOUNTABLE_BOOT_VOLUME to a blank screen

[veeumbra]

So, I come home and boot up my computer and it starts booting as normal but it's taking forever. After a while of waiting, I get a message saying UNMOUNTABLE_BOOT_VOLUME accompanied by a sad face emoticon. Afterwards, I get a screen with the HP logo saying, Preparing Automatic Repair. After that screen, the screen goes to a dark grey or black colour and doesn't do anything. The fan continues to run, I've left the computer on for about 5 hours, I've also tried mashing F11 and it just goes back to the blank screen I've also tried booting from USB and CD and it also just goes back to the blank screen. I'm in desperate need of help.

As I understand you are getting an Unmountable boot volume error and Windows 10 fails to boot normally on your HP Notebook. Don't worry as I have a few other steps to help you get through this concern,

The unmountable boot volume error can be caused by:

• A faulty hard drive.
• A corrupt boot partition.
• Corrupt Windows files.

Let's try these steps here:

Automatic Startup repair: 

1. Turn off the computer.

2. Disconnect all connected devices and cables such as Personal Media Drives, USB drives, printers, and faxes. Remove media from internal drives, and remove any recently added internal hardware. .

   Do not disconnect the monitor, keyboard, mouse, or power cord.

   .

3. Turn on the computer and repeatedly press the F11 key about once every second until the Choose and option screen is displayed, and then continue.

4. On the Choose an Option screen, click Troubleshoot.

5. On the Troubleshoot screen, click Advanced Options

6. Click on Automatic Repair and wait for the process to be completed.

Use The SFC /SCANNOW Command

The SFC command can be used to replace corrupt and missing system files. Here’s how to use it:

1. In the Command Prompt window, type sfc /scannow > Press Enter
2. You can also try using the chkdsk /r command in addition to the sfc /scannow command.

Run an extensive test on the Hard drive as well as Memory from F2

Depending on the test results, If all the test passes, I would suggest you perform a System recovery using the recovery media. You can check if the recovery media is available for your PC online on www.hp.com/drivers. If the recovery media is not available, I would suggest you contact our HP phone support to order one. Please fill in the product details to get the tech support number.

What you can do, is use the following link to create yourself a case number, then call and it may help speed up the call process: 

Step 1. Open link: http://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect 
Step 3. Scroll down to "Still need help? Complete the form to select your contact options" 
Step 4. Scroll down and click on HP contact options - click on Get phone number 
Case number and phone number appear. 

I hope this helps. Let me know if you need any further assistance. I'll be happy to help.

I've pressed F2 repeatedly and gotten into the HP PC Hardware Diagnostics UEFI and I can't find a button saying system tests. Attached is a photo that shows exactly what I see. If you can't see it well it says: Memory Test, Hard Drive Check, Language, and Exit.

Hi @veeumbra,

Thanks for replying, I see that you are on the Hardware diagnostics screen with the options such as Memory Test, Hard Drive Check, language, and Exit. Let me go ahead and assist you from here:

Testing using HP Basic System Diagnostics

If the hard drive is not detected or is reporting problems, the following screen is displayed with two testing options: Memory Test, and Hard Disk Check.

Running the Memory Test in System Diagnostics

To run the Memory Test, use the keyboard arrows to select Memory Test.

After starting the test, there are two screens displayed: test in progress, and after the test, a pass or fail screen.

Running the Hard Disk Check in System Diagnostics

To run the Hard Disk test, use the keyboard arrows to select Hard Disk Check.

After starting the test, there are two screens displayed: test in progress, and after the test, a pass or fail screen.

Please respond to this post with the result of your troubleshooting. I look forward to hearing from you.
