[problem description SNIPped]

If nothing else solves the problem, you can always put the drive
in another machine and using that machine's functional OS
transfer your data to wherever - first running a suitable set of
AV/malware scans on your drive FROM THE BOOTING DRIVE/OS to see
what the hell is (or is not) going on with your HD. It could be
your MB, a driver problem, or one of dozens of other things.

Of course you will either need to use an external enclosure or
the "other" computer will have to have a case large enough to
put your HD into, or at least enough cable length and space to
plug in your drive and put it somewhere stable. It is not
necessary to actually INSTALL it inside the machine, just make
sure not to knock it off whatever it's on while you're working
with it. OR when it's just sitting there.

(I wasn't aware there is no recovery/repair in OEM versions. IMO
it's still MUCH better to have an OEM disc than a "hidden
recovery partition" full of ads and other crap. Oh well. You are
better off doing an image of a perfectly set up C partition
anyway and forgetting about "restores". Keep all your data on
other partitions.)
