Hello All,

First let me preface this with: I have a full system image backup for this machine from prior to when this began occurring (today, after a "long nap") so I can restore if that's the best thing to do. This is a backup machine that has had no activity on it since the last system image was taken. I'm asking what follows for my own education.

Today when I tried firing up my old HP laptop with an A8 APU, it was hanging at boot after the POST screen. So, I did the triple hard power-down technique to get Windows to try to repair itself. It didn't. Tried a second cycle, which triggered a chkdsk as part of the repair process, but it still would not start. I get a message stating that Automatic Repair couldn't repair your PC and telling me that the log is in D:\WINDOWS\System32\Logfiles\Srt\SrtTrail.txt.

I then try to boot into Safe Mode with Networking, and get a BSOD with the error code BAD_SYSTEM_CONFIG_INFO. (What a shock there!)

Just wondering if there is a method that could be used to make the machine "snap out of it" other than a restore? Though if the restore would be much less time consuming I'd just go ahead and do it if it's well known that this particular error code needs a deep dive into many dark recesses of Windows 10 in order to resolve otherwise.
 
Hi Brian,

Is it possible to get in plain safe mode?
 
Have you attempted to boot into a WinPE?
 
I've never personally dealt with this bugcheck, however, if you're able to obtain the dump files - particularly MEMORY.DMP - then we may be able to pinpoint the issue.
 
I have not gone any further than trying to repair startup and, after that failed multiple times, booting into Safe Mode.

I'm more than willing to try anything if someone wants to continue pursuing this "just because." I understand that curiosity can drive that. If, however, no one does feel free to say so and I'll just practice my restoring skills!
 
OK, finally had time to fire up Linux Mint live, and am attaching the SrtTrail.txt log along with the only two DMP files that have yesterday's date (Zipped). There is no MEMORY.DMP to be found.

The dmp files are live kernel dump files 0x187, the desktop windows manager couldn't initialize which is likely related to the corruption in the configuration database.

Are there also no files in Windows\Minidump?
 
Hi,
the Hive "System" as stated in the BSOD is damaged, one or more entiies are not readable.
If your lucky in folder RegBack is an earlier copy of that filesystem_config.PNG
rename the damaged on from within PE-System or Linux, copy !!! the file in RegBack to the config folfer.
Win will start now.
If the RegBack folder is empty, you need to restore the files from your backup.
Thats all you can do.
 
If anyone has specific files they'd like me to search for and provide, please give me either the name itself or the wildcard pattern I can use to search for them. This is not my area of expertise and so having those names/wildcard patterns is what will make me able to find and provide more data.

If it turns out whatever is being sought is not there, I appreciate the advice I've received so far and will follow it.

The system has not been updated recently. It was put away probably between 1.5 and 2 months ago and was up to date, and functioning, when shut down then.
 
IF a registry backup is present.
Automatic registry backup was removed in version 1803, and onwards.
In fact I haven't got files in C:\Windows\System32\config\RegBack>.
(But I updated windows to the latest version only some days ago...)

The system registry hive suggested by MichaelB could be in that path, and it's named SYSTEM.

*.dmp in Windows\Minidump
 
I decided to do a search for every .dmp file anywhere, and the only ones besides the two I already posted that date from 2/20/2020 are in the attached.

Definitely no minidump files.

Just to confirm, you're searching using the Linux distribution right?
 
Yes. The machine has not been booted using Windows since February 20th. All other access to the HDD on the machine has been made using a live Linux Mint 19.2 distro.
 
No items are in the C:\Windows\System32\config\RegBack folder.

This machine was on 1909 shortly after it was released.
then your onliest Choice is restoring that file from your baclup you mentioned above (and mentioned by me) od do a full restore.
Any other action will not bring you to the booting system, just do it.
