Windows 10: 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!
