Can't login or use correct password after attempted upgrade

Specs: Windows 8 ?, Intel Core i7

I helped someone set up a new Windows 8 PC, transferred data from old PC, etc. and then a few days later, they tried to upgrade from Windows 8 Home to Windows 8 Pro and it failed. Now it boots up but won't accept the correct password. I logged into the Microsoft account on another computer and the password worked. I changed it and tried on the Win 8 machine again, and no success. I used Hiren's CD to do a password reset and it couldn't find the registry info. I tried a Trinity Rescue CD and it couldn't find itself, or the RAM drive or something. So, I think everything's there, but the configuration got hosed on the attempted upgrade. I can't boot into Safe Mode with Shift F8. I tried using the Windows 8 CD and it said the drive was locked when I tried to do a Reset or Refresh -- "The drive where windows is installed is locked. unlock the drive and try again."
In Advanced Options when I try to run CHKDSK from the command prompt I get "Chkdsk cannot run because the volume is in use by another process.
I can run Mini XP from the Hiren's CD and look around...
Any ideas?

Long shot: Try to login as administrator with a blank password.

Try F8 without the s--- key & try F12 too.

In this case use the PCname\user(PC name as it is on the network) and no password then press enter key.
You said you've used Hiren and others but still the same, I would advise you try Window XP 2009 Dark Edition SP2.
To get to Safe mode: Try to set from slow boot then press TAB key after POST or force PC to turn off by pressing power button to see Safe mode option. If work then restore to the date you are sure of the PC perfect worked.

In case you have to restore back to factory setting:
First of all: Slave the PC HDD and backup all recoverable data then reassemble it back to the PC and start the PC then you press ESC or F11 depend on the PC.

Not sure if it is similar and must have been fixed by now. Still, here are my 2 cents. Today I observed that the special characters on the keyboard are not exactly what you get when you type them in the lock screen text box. e.g. @ appears as " and vice versa and so on it is all garbled except the basic char/num keys. There is a password text view "eye" button. You may check if there is such garble in the password that your think is right as per the keyboard but which actually may be a wrong one. other suspects: CAPS lock etc
