SP1 installation error: 0x800F0A12

[Ed Cryer]

This seems to be due to me having used Paragon backup & restore on my HD.
I've tried MS' suggestions at;
http://tinyurl.com/5r2r6s5
without avail.

A bit of googling shows me that it's very wide-spread; different people
recommending different solutions. The following two look best to me. But
before I launch into time-consuming trial and error, has anybody here
got experience of this?

1. Give drive letter to System Reserved (100MB) partition.
2. Set C partition as "active".

Problem solved. SP1 installed successfully.
How?
By using Command Prompt, typing in "Mountvol /E", re-booting and running
the update again.

Sheesh! Well, I must admit that MS did mention that in one of their four
possible solutions. But who solved in on my PC, Alias?
Me.
I did it. With no support here.
I did it on my own.
Me, the pioneer; the man who confronts the universe face to face;
doesn't follow the herd; doesn't build his self-image on social icons;
builds it on reason, the precepts handed down from ancient Greece, and,
perhaps, some genetically given stamina that won't let him give up or
choose the easiest option. Me and Davy Crockett, Alias; me and the great
existentialist thinkers!

Next: clean the Augean Stables.

I find that your approach as described above works for me too. Usually.

According to MS "mountvol creates, deletes, or lists a volume mount
point. Mountvol is a way to link volumes without requiring a drive letter."

My internal HD has C, D & a couple of partitions without letters. One is
the OEM restore partition, the other a 100MB partition created by setup.

As to just why I had to run mountvol, and why SP1 setup couldn't have
been more specific and helpful, I don't know. My guess is that I use
Paragon Backup & Restore on the whole volume, and I have restored it at
least once; and it didn't set the markers that MS software would have done.
If so, there will be a lot of people in the same situation.

P.S. I've just got back from a short holiday in Athens. I had to watch
the locals rip up Syntagma Square and burn things. The ghosts of
Aristotle and Plato must have turned in their graves.

Here is MS's suggestion of a program to use BEFORE installing Win 7 SP-1
http://support.microsoft.com/default.aspx?scid=kb;en-us;947821

It is a "System Update Readiness Tool"

Fair enough, yes. I appreciate your responses. But what happened to me
in real time was that the SP1 appeared in my Win Update; downloaded and
run; failed with error message.
I then searched around, came to the conclusion that it was an unmounted
partition, ran mountvol (which, BTW, no one mentions in your URLs) and
it worked.

I'm an experienced computer programmer and I have good intuition about
problems. But many don't.

It shouldn't have happened. MS should have foreseen it and taken
prophylactic action; not leave it up to us to solve ourselves.
All previous Win updates have worked ok. This was the first to fail here.

I tried using that system readiness tool but it does the same as SP-1. It
gets so far and then stops installing. Hangs up.

Have MS left it up to you to let me know after the event?
Why didn't they let me know beforehand?
It's not in Windows Update nor the history.

So then, now that I've solved the issue myself, do I download and run
this thing or not?

That temporary apparent hang seems to be the norm, even with people who
get SP1 installed first shot.

See my post above under your thread. And if it works and SP1 goes in,
run the SRU tool (after setting a restore point) and let us know what
happens.
I have the thing ready to run, but very little time available right now.
