MSI laptop - reboot & now unmountable disk - acpi issue?

Hello, I woke up this morning to my laptop boot-looping to the MSI screen and then going to a Windows message that says, "Unmountable Disk".

Everything I've found online, like booting from the Win10 disk failed by freezing every time. No matter what I've tried, I can't get past initial load - just sits at the black screen forever.

I've had some success to confirm some things. I booted to a live USB of Ubuntu to see if I can access the disks and that proved to be difficult - freezing as it entered the Ubuntu desktop. I was finally able to and can boot successfully into the Ubuntu desktop, but I had to set acpi=off to get it there.

While there, I can access both my 12gb SSD and 1tb sata drives with no issues. I was able to copy off some data and it appears there is no issue with the drives.

Keep in mind - I had to disable ACPI in boot when booting to the Ubuntu live USB stick. If I didn't, it demonstrated the same behavior as when trying to boot via Win10 Boot USB - it just gets stuck on the black screen.

I then created a Win10 bootable USB, using the media creation tool and it seems like it hits the same snag Ubuntu did initially - I get the Windows logo and then it goes black and nothing happens after that.

So at this point I'm not sure where the problem is. Could it be the SSD? It's readable, but not mountable. Is there a way to disable ACPI when booting into the Win10 boot USB? Since it worked with Ubuntu.

I've opened up the laptop, reset the battery on the board, reset bios and upgraded bios to latest.

Is there a way to disable ACPI for Windows or in the bios or to get it to boot straight through?

I'm at a loss here. I don't know what happened and I have no idea how to get past this problem.

Thanks in advance! for any help!

Well .. I been at this a while and I decided to try and buy a new SSD drive. It was only $30.

Still would love to hear any other ideas on how to resolve. Redoing the entire setup on this laptop will (not) be fun

But, if that's the only way and on a new drive... It is what it is..

Did it work? Curiosity killed the ferret.

Ordered yesterday. Should arrive by end of week

The unmountal boot volume can be fixed by replacing hardware but this also replaces the software and the software may be the problem.

The UNMOUNTABLE_BOOT_VOLUME bug check has a value of 0x000000ED.
This indicates that the I/O subsystem attempted to mount the boot volume and it failed.

If you want to troubleshoot the software that can be done.
(drive file system, boot files, operating system, etc.)

Find a flash drive that you can format ( > or = 8 GB)
Create a bootable windows 10 iso:
Download Windows 10

If you prefer the drive replacement that will be faster.

If you prefer to troubleshoot indicate when you have the iso ready and steps can be posted into the thread.
For the steps please use a camera or smart phone camera to take pictures and post images of the commands and results into the thread.

The steps that can be provided will be more detailed.

If attempts to boot to the Windows 10 iso fail you can also try Kyhi boot rescue.
Windows 10 Recovery Tools - Bootable Rescue Disk - Windows 10 Forums

If Kyhi boot rescue works then you can test the drive using
HD Tune (Health or SMART, Benchmark, and Full error scan) > post images of the result into the thread

Crystal Disk
CrystalDiskInfo Crystal Dew World
Macrorit:
Check Hard Disk for Bad Sectors | Scan Disk on Windows
etc.

Followed by chkdsk /r

Good. Hopefully that will solve your problem.

Worked with no issue - like it was a brand new laptop!

You could pull your old SSD out of the computer and attach it via a USB Adapter, Dock or Enclosure to a working computer. If it gets recognized you can run Diagnostics, and recover any files off of it.

So I was able to restore and move all of my files off when I used the Ubuntu boot USB, so that was OK. That was fairly easy.

But, I didn't know that they made an SSD drive adapter like the one you linked to - so thanks for that!
