Windows 10: After restart goes to x drive will not boot c drive renamed

Did a restart and window 10 went into repair mode and said it could not fix it. went into command prompt and found my self on x drive. look around and found my c drive renamed to j drive, did a dir command and found all my windows files there. one of my others drives now has the c label.

A similar event happen last fall when a windows update snafu caused a problem on two systems with the same results. That time I did a clean install.

BSOD - drive C changed to drive X

After the restart following the 11/18/2017 Win10 64bit Pro update, I have the BSOD with stop code 0xc000021a. I am able to access the command prompt....Troubleshooting revealed that what was drive C is now drive X. At the command line, I can access a drive
C is but it is empty. A directory listing of drive X appears to show everything that should be on drive C. I suspect the update possibly failed at some point causing this problem. How can I fix it?

Hp notebook will not boot. Booting from usb drive shows recovery drive as C:

Just looking at a friends Laptop.

Booting this HP notebook gives a message "Boot Drive not found"

"Please install Hard Disk (3F0)".

Using provided recovery does not work and there are no backups.

I am using a recovery drive from my own HP Notebook to investigate.

Using Diskpart List Disk and Partition I can see a drive with 931gb size and 899gb free

I can see a Partition of 32gb of type Primary. This is the recovery drive which boots as drive C: currently. The old C: drive and partition have vanished.

Looking for another view on this I ran fsutil volume list to show three volume /drive combinations

C:/, D:/and X:/.

The X:/ drive is probably my usb drive.

I tried to get a volume allocation report from D:/ using fsutil and got "The device is not ready". Maybe this is just the DVD drive?single

My questions is. Can I get the drive remapped without losing data.
