7 HP x64 - Startup Repair Loop, NoRootCause - two Win7versions on PC

Hi SIW2,
thank you! I tried that. It seems the same thing that you can do in the command window start can be opened as part of the Windows repair options, as, for example, explained as solution 3 in "https://www.deskdecode.com/startup-repair-cannot-repair-this-computer-automatically/"
Indeed, I did find the backup folder needed for that in windows\system32\config\


But it did not work.

Than I had the most clever idea to copy these files from the currently running win7-version. It would not let my copy because they were currently "active". So I had the brilliant idea to make a copy of THESE files, so they would not be active and then copy them into the damaged version's folder as you suggested. That did not work either.

@Paul: I cannot get into the safe mode but what I was able do ist to boot with command prompt. So what happens is that it always stops at reading the drivers/classpnp.sys. It stops a moment and then shuts down.

So I started to look for a solution for that problem. The first advice I found was to disconnect any unnecessary hardware and run checkdisk over and over 3-5 times, not only ones. Then try to run SFC also.



Thats what I will try next step this evening. I'll keep you updated if I find out anything.
Thanks!

From the healthy win 7 disk, do a check disk
Open a CMD window and type:
chkdsk x: /f (replace x: by the drive letters on the target disk)

Thank you Megahertz!


I tried that - with administrator properties. No error found.
I tried sfc from there - did not work.
Also tried every other command suggested in threads - rename etc.


I then was focussing on the threads that treated the issue that when booting in the command-prompt mode,booting would always stop at the driver "pnpclass.sys"


According to many threats I should remove all not needed hardware since it might be a hardware problem.
Did that but no effect. In my situation I do not think that it is a hardware problem since all hardware is working correctly using the old Win7 version on the other drive.


So after trying some promising ideas that I could find in the internet, I haven't advanced and I think soon I'll give up and do a clean re-install.

From the the healthy win 7 disk, open disk management (C:\Windows\System32\diskmgmt.msc), expand the window, expand the columns so we can read them and with the sniping tool take a snapshot of the whole window.
Place it here as an attachment. Use the paper clip on the answer window - browse to the file - upload.

Hello Megahertz,


attached you can see the screenshot, I hope this picture will do.
It is in German, but should be understandable equally.
As you can see, I have 2 drives: the one ("Datenträger 0") with E: and G: which is the SSD with the broken windows version.
Then the magnetic old HDD ("Datenträger 1"), with H: C: and F:, where, luckily, the old Win7 installation was left and is running now -veery slowly and noisy- but permitting me access to the data and to the SSD drive

"Fehlerfrei" below the disk letters means "without problems/errors".
That's where I am, without really knowing where to look for the boot error in the SSD drive, having tried most of the suggestions I could find in the forums.


Best regards

Why didn't you use the snipping tool (%windir%\system32\SnippingTool.exe) to take the snapshot?

As you have two boot able disks:
- Shutdown
- Detach the HDD ("Datenträger 1")
- Boot from the Win 7 installation disk, go to repair and do a start up repair.
- Don't attach the HDD and try to boot from the SSD
- Report
