That was a good idea.  I ran SpinRite (no problems found) but the bootrec /fixboot still gives "access denied".  So then I cloned the drive to a brand new drive, but it's the same problem.

There must be another MBR fix utility out there.

It could be a bad sector on the boot section of the drive.

Spinrite is a useful tool for diagnosing that, and in some cases fixing it
to the point where you can at least boot the drive and/or get the data off
it.

Are you sure there are no external drives are plugged in? External drives
can sometimes re-order the way 10 sees the drives. I have had this happen
more then once with windows 10.

I've had this before, and normally I boot to the recovery environment

then:

Rename the current BCD and rebuild it with

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

But this time, I get "access denied" when I do the bootrec /fixboot -
all
the other commands succeed and it rebuilds the BCD, but still no
boot.  So
I'm convinced it's the fixboot part that isn't working. However, I
can't
find any links in Google that would point in in the right direction.

Any ideas?
