Yeah, that's why I originally said "If the F11 option still works ..." it didn't
The restart+shift was a good idea, but I wanted to see if the HP recovery op still worked, it didn't
Then I realized that the Recovery partition on your drive was way too small for Hp Recovery, so I abandoned the idea completely.
Don't count on HP to keep the drivers up to date after about a year's time. Let me rephrase that, don't count on HP updating older model support pages after about a year's time. They do house newer drivers, they don't make it easy to find them though. MS is managing Windows drivers though WU - they get the driver from the OEM and run it though a slew of tests on a slew of machines. Then they offer it through WU - that's the best place to get drivers now-a-days.
A case in point - the finger-print reader on my dv6 stopped working about a year after I bought the box, Validity, the software vendor was bought and sold a few times and there wasn't a good driver for 2 or 3 years, even when the dust cleared, the driver supplied by Validity had issues. I had given up ... unit I started testing Win10 ... WU supplied a driver for the fingerprint reader was loaded and it worked! And it was a Validity driver. So do not discount Windows Updates and drivers - I did before Win7, then Win8 was nearly perfect and Win10 follows that track record.
You can look in Windows.old to see what's there. Check the Users folder - if your data is there, copy it someplace safe.
Sorry, no you cannot use another key. You can use another disc.
But... now I see that you do not have the COA sticker on your machine.
This is GREAT news Obizan.
