Run into the same issue last thursday.
I made the device quasi-operational by disabling the graphics card.
You can do this either by either booting up in safe mode or connecting external display via usb-c dock. Both will let you in.
Then, disable the "Intel Iris Xe Graphic" in "Display Adapters" tab in the Device Manager. Windows will then use some basic software render and the integrated display will work. However you will not be able to connect external display.
You can turn it back on to make external display work, but don't forget to turn it off again, because getting to safe mode with black screen is kinda tedious.
However, the software rendering is sort of sluggish, so it's definitely not a permanent solution.
Hi,
I have a 3 month old Dell ECS 1250 running Windows Home 11. Apparently I took the Jan14 update. I was on a Zoom call and later in the day first the audio when out, then the video went out and the machine rebooted. Thereafter I would get a Dell logo then a blank screen; I cannot boot into safe mode or anything related to windows. Two calls to Dell support and it is pretty clearly not a HW via various diagnostic test. It is the destructive MSFT patch.
Using F12 on power up "Advanced troubleshoot" and "Recovery" options, I have tried the following all to no joy:
-
remove the feature update
-
remove the patch update
-
run the repair
-
run a fresh install via the local and cloud download/update options (with and without saving my data)
-
New install
What happens on the attempted new and fresh install is it gets about 10% thru per the progress bar, then the screen flickers and then goes blank; no restart, nothing; the monitor just goes blank aka the install has failed; no error nothing just a blank screen. Monitor works fine as I am using it right now on windows10*.*
From "Advanced troubleshoot" screen, DOS command prompt tried these commands
to no joy. Same result as others have shared bz via recovery you are not an Admin, so you have limited execution/access rights:
bootrec /fixmbr → worked
bootrec /fixboot → Access Denied
bootrec /scanos → 0 Windows installations found
bootrec /rebuildbcd → 0 installations
I also have tried as
DISM.exe /Online /Cleanup-image /Restorehealth
this won't work bz you have to be an admin. It errors saying these param are unrecognized.
/Cleanup-image /Restorehealth
Reading thru my AI chatbot Gemini, it implied 3 possible issues are at play here with the Jan patch on my Dell machine (visible via F2 on machine bootup)
-
Secure Boot
-
TPM2
-
CA Cert
From F2 - Dell Bio configuration page I made the following changes. The fresh/New install still only goes to 10% and dies aka screen goes totally blank.
-
Secure Boot (Disabled/Off)
-
TPM2 (now set to clear the TPM2 cache on startup)
-
CA Cert (not 100% sure with this but I changed it from strict to a less strict setting)
After still failing it suggested I change the "Post time" on startup from "0" to a longer time so I set it to "5 seconds. It still fails (I assume this is the same as changing from Fast Startup)
Anyone have any solutions, suggestions etc?
Thanks!

I ran into the same issue on the same product recently and I'm 90% percent sure it's something wrong with drivers update.
I can log in to the system with Windows Hello (can hear the sound) but the display just won't turn on.
So the safe way to get out of this imo is to format and install, and totally disable network connection to prevent the faulty driver being installed automatically.
I ran into a similar issue with a black screen after login, except i couldn’t open task manager. Was able to get mine fixed:
- Ctrl-alt-del. Click the power icon, then hold shift and select restart.
- After it loads, it should open a blue screen. Troubleshoot -> Advanced options -> Startup Settings -> Restart
- Select 6. Enable safe mode with command prompt.
- Log in.
- (probably optional, but did it anyways) Click on the terminal window and type sfc /scannow. Press enter, and wait for it to complete.
- Type explorer. Press enter. This caused the taskbar and the typical windows desktop to appear.
- Press Windows+R and type regedit. Click ok, then yes if you get a prompt.
- On the left side, navigate to Computer -> HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Control -> Session Manager -> Environment (click the environment folder).
- If you don’t see windir in the list on the right, add it. Right click an empty space on the right side of the menu, New -> String Value. Type windir, press enter. Double click windir. Under value data: enter C:\Windows
- Press ok, then restart your computer. After logging in the issue was resolved for me.
Turns out I was missing the windir environment variable. Hopefully this helps someone (the other threads out there are locked :’)
