A friend asked me to ‘fix’ her HP Pavilion PC which cannot be started… I have done below, to no avail. I have 3 recovery CDs that came with PC (see below)

Question is How to start/reset/ PC - Likely WIN 7 - unfortunately upgrade to WIN 10 is no longer free.

Attempting to start WIN 7(?) HP laptop returns… " The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To install windows , click "oK" to restart the computer, and then restart the installation"

I press “OK” and PC repeats above message. — not much help here… “This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread.”  IMPORTANT SEE (20) BELOW

HP PCs - Performing an HP System Recovery (Windows 7)
HP and Compaq computers that came with Windows 7 installed.

Recovery Options:

Continue - does not work

Use a device - Will not load Recovery System from internal CD drive

Use another Operating System - there is none

Reset this PC, Keep my Files - no, “…There aren’t any administrative accounts on this PC”

Reset this PC, - delete all files - “There was a problem reseting this PC.”

(20)      On the same error screen press SHIFT+F10 and it will open up a black Window. (a command prompt window)

(21)       In  the black windows type the word "regedit"(without the inverted commas and hit enter. That will open the registry editor.
        In the Registry Editor..
                Browse to....
        HKLocal machine/SYSTEM/SETUP/STATUS/ChildCompletion,
and after highliting child completion,on the right hand side check for setup.exe. if the value is 1 change it to 3.(by double clicking on setup.exe and changing the value shown in the box).

Then close the registry editor and then also close the black window.
Then click on OK for the error and the computer will restart and the installation may complete. 

“just try it and let me know if it worked.” - No, just continues to cycle and return “Installing features and drivers” … “Configuring settings 0%”

So, How do I get this HP PC to work?
