Repair safe mode - windows 10 dont work!
« on: August 27, 2015, 11:10:21 am »
hi,

I have a strange issue I have been trying to fix for a few days, I have been getting the black screen of death when trying to boot into safe mode.
But Normal windows desktop booting works just fine, as I said its strange, I cant to seem to fix it, I even got a new hard drive and cloned from the old system just in case other drive was rotten.
Tweaking.com - Windows Repair is a nice tool and has done nice work of fixing issues, but the safe mode repair option dose nothing to fix my issue.

P.s the type of black screen of death issue I have is when you only see the mouse cursor and nothing else response like ctrl+alt+del.

tested methods used so far: windows repair disc dont fix issue, sfc /scannow unable to fix issue, upgrade install windows dont fix it, so I am lost what to do.

hope you can help me save my safe mode.
thanks

Safe mode only lets certain drivers and services run, if the system needs something to run in safe mode and it isnt starting up then you get the blank screen.

Right now my program does put back the default registry keys for the defaults that are allowed to run in safe mode, it doesnt delete any. So i am wondering if you have a driver or service that is needed in safe mode, or if the the default ms driver which windows uses for the video isnt working right.

I had one other user who had windows 10 who couldnt safe mode to come up as well, even when he did it manually. I would love to find out the reason for it so I can add a fix into the program :-)

So when it happens can you check the event viewer and see if there is anything logged?

hummm in normal boot not safe mode go to the login screen and on the power options hold shift while you click restart  and try to enable low res video. I wanna see if that fixes it for you.

I attached todays event log for you,

I used your suggestion and its didn't work, error when trying was: Failure to display security and shut down options

I just wanted to comment on this post a bit.....

I was having a black screen issue when my PC would cold boot.  I would see the Windows 10 splash screen and then the screen would go black for 16 seconds or more before it would display the login screen.  I was told that Windows changes resolutions during the cold boot and that this was most likely a video driver issue and many have found success by completely removing the old driver and then reinstalling it.  I was also told by a Microsoft person that they are aware of this black screen issue for some time and they are still looking for a solution.  In my case it as not a video driver issue but something that Windows Repair did fix (mostly).  Now instead of 16 seconds or more of black screen the screen goes blank for probably less than 1/2 second.  Perhaps you should check with your graphics card manufacturer to see if they have a more recent driver that would be more compatible.

One comment that I will make on the safe mode issue is that my PC still has an issue with Safe Mode.  In the instructions for Windows Repair, it says to boot into safe mode with networking but each time I booted into Safe Mode from within Windows Repair both my network and my audio were turned off.  Apparently Windows Repair didn't need networking to fix errors but it concerns me why networking was turned off.  I was assuming that there would be options like what I had under Windows 7 that would allow you to boot into safe mode with or without networking but since my screen was going black on boot up I didn't know if the options were being displayed and I just couldn't see them or whether there something wrong with my machine.  What I was wondering is whether Windows Repair boots you into safe mode with networking and I have a problem or whether it simply boots you in safe mode and requires you to choose?

It uses bcdedit which is a command in Windows to boot into safe mode with networking Next time you hit that safe mode button before you restart open an elevated command prompt and type in
Code: [Select]
bcdedit /enum and at the bottom you  Will see the safeboot option.
