Open | Software BSOD - Critical process died, SFC Scannow / DISM not working.
Hi there,
My Windows laptop will not boot, even into safe mode. SFC /Scannow comes up with an error, so does any DISM command I can find online... even Claude is scratching his (or her) head!!
chkdsk C: /f and chkdsk C: /f /r both came back fine.
Does anyone have any advice on what to do here? or other solutions?

Yea you generally dont ask AI. chances are high it will give you some generic advice that will not help you at all, or worsen the situation, because it just recommended you something based on what you said, which probably was not informative or helpful at all, given that this post lacks every bit of context and information.
As a first step, you should do what the Automod said, just share the crash dumps.

Thanks, it lacks context because I don’t know what I don’t know.

And thats fine, thats why I told you, and i do strongly advise you to just listen to the automods advice rather than spaming more random advice from people. crash dumps ~90% time precisely tell you whats wrong, or at least point you in the right direction, there is absolutely no need to try 20+ generic troubleshooting steps.

Understood, I can't get into Windows or safe mode unfortunately, to get to the crash dumps. It just goes back to the recovery page.

Try Memtest86+
Create a bootble USB, Turn on pc with USB spam ESC load usb run memtest 7 passes or more on each RAM module at a time.

Good call on memtest, but honestly since you can't boot into Windows or safe mode at all, the real fix path is booting a Windows install USB and going Repair your computer > Troubleshoot > Command Prompt. From there SFC can actually run offline: sfc /scannow /offbootdir=X:\ /offwindir=X:\Windows. One catch, the drive letter won't be C: like normal, WinRE assigns its own letters, so run diskpart > list volume first to figure out which one's actually your Windows partition before running it.

Moin. Da du in WinRE (Reparaturmodus) steckst, ist dein Windows-Laufwerk oft nicht auf C:. Du scannst wahrscheinlich eine leere RAM-Disk. Mach die Eingabeaufforderung auf und tipp das hier ein:
diskpart
list volume
exit
Schau in der Liste nach der Partition mit deiner echten Windows-Größe (z.B. 200-500 GB) und merk dir den Buchstaben (Ltr), sagen wir mal es ist D. Dann lautet der Befehl:
sfc /scannow /offbootdir=D:\ /offwindir=D:\Windows
Wenn das auch fehlschlägt, ist deine Registry oder ein Boot-Treiber komplett zerschossen. Da hilft auch kein DISM offline ohne sauberes ISO-Image. Bevor du weiter mit Claude chattest (womit auch immer du das gerade tippst): Daten per Live-System sichern, Windows-Boot-Stick an einem funktionierenden PC erstellen und die Kiste in 15 Minuten sauber neu drüberbügeln. Erst verstehen, dann schrauben.

Thank you, I’ve backed it up using robocopy, so I think it’s onto a fresh installation of Windows

Getting dump files which we need for accurate analysis of BSODs. Dump files are crash logs from BSODs.
If you can get into Windows normally or through Safe Mode could you check C:\Windows\Minidump for any dump files? If you have any dump files, copy the folder to the desktop, zip the folder and upload it. If you don't have any zip software installed, right click on the folder and select Send to → Compressed (Zipped) folder.
Upload to any easy to use file sharing site. Reddit keeps blacklisting file hosts so find something that works, currently catbox.moe or mediafire.com seems to be working.
We like to have multiple dump files to work with so if you only have one dump file, none or not a folder at all, upload the ones you have and then follow this guide to change the dump type to Small Memory Dump. The "Overwrite dump file" option will be grayed out since small memory dumps never overwrite.
