Hi, I seem to be having an issue during start-up.
First: My Desktop PC was powered off for about 16 hours, and when I
had shut it down, it shut down normally at that time.
Second: When I turned on my PC, the Windows 10 logo screen appeared
as it would normally do, but the circle of dots remained on for an
extended period of time, and then a blue screen appeared saying
that "Your PC ran into a problem, and needs to restart". At the bottom
of that screen a stop code had said "UNMOUNTABLE BOOT VOLUME".
Then the PC rebooted with the Windows 10 logo screen and the
circle of dots with a message saying "Preparing Automatic Repair".
Third: After that screen disappeared, what looked like a Command
Prompt window briefly flashed onto the screen, and then I had seen
nothing but a black screen.
What I would like to know is 1). In general how long should the
Automatic Repair mode be running, And 2). What is causing the
Unmountable Boot Volume.
It has been suggested by reading some of the posts within
the community, that my HD may be at fault, is this true?
For point of reference, I have a HP All In One Desktop PC
that was purchased in early 2011 with Win 7 installed.
And except for an issue with the optical disc drive
(CD-R, CD-RW, DVD, Blu-Ray) that occurred in late 2015,
the PC has been functioning normally.
And also for point of reference.
Just before the expiration date for the free upgrade to
Win 10, I had installed Win 10 on my PC, and it has also
been functioning normally, as also with the recent
Win 10 Creators Update that was installed in Mid-June of
If anyone within the community can tell me what is going
wrong with my PC, it would be very helpful, and greatly
Thanks in advance.
