Unmountable boot volume stop Code - Windows 11

Anonymous

So, I have a HP Pavilion x360 Covertible (Model: 14-dy0518sa) with a Samsung NVMe SSD. While running a game, it crashed, probably due to being under specs (my bad) and it crashed. Wouldn't bring up the option to end the process or wait for it to respond. After about 15 mins or so of waiting, I powers the device off using the power button. When powering the device back on, I received the 'unmountable boot volume' stop Code and a 'boot loop' with this BSOD. Using the on board BIOS, I noticed the SSD is still detectable by BIOS, however not via any other means. The OS had disappeared and I had no way to boot to windows.

I used the MCT to create a fresh install of windows on an external HDD (created a 30gb FAT32 volume and used this). When launching the installer, I couldn't repair using the startup repair options. Using CMD, I ran Diskpart which also did not identify my SSD.

I've tried reinstalling the Intel RSD drivers from the HP Website but this has been to no avail either. Looking for advice on how to proceed as I am at a loss.

Thanks in advance!

    Hello Ollie Dawson,

    Good to see you in Microsoft Community.

    If you can boot to winRE screen via system recovery media, then you can try the following steps:

    Image

    1. Select "Command Prompt", then log in with your account, and run the commands below. This will rebuild the Windows system startup items. 
       sfc /scannow

 bootrec /fixmbr

 bootrec /fixboot

 bootrec /scanos

 bootrec /rebuildbcd
    2. If you installed the system update before the system is abnormal, you can use "Uninstall Updates" to uninstall recent updates (which include Quality updates and Feature updates, try both).
    3. "Startup Settings" > "Restart", after the restart, you'll see a list of options. Select 4 or press F4 to start your PC in Safe Mode. Or if you'll need to use the internet, select 5 or press F5 for Safe Mode with Networking. Then log in normally. If you can successfully enter safe mode, run the commands in step 2 to repair possibly corrupted system files.
    4. If you have created a system restore point before, you can restore it to that state using the "System Restore", but the data since the establishment of the restore point will be lost, please operate with caution.
    5. If none of the above solutions work, you can reset the system (on the Troubleshoot page), and you can choose whether to keep your user data or not.
    6. If there is not any progress, you can boot from your USB Boot Drive, run the installer, and select "Upgrade: Install Windows and Keep Files, Settings, and Applications", which will in-place upgrade the system without affecting your personal data, just update the core system files.

    If anything is unclear, please do not hesitate to let me know.

    Best Regards,
