Reboot the system three times, and before the blue screen appears shut it down using the Power button. The aim is to interrupt the process, such that the Windows should boot into the Advanced Mode. Once it goes to the advanced mode, choose Troubleshoot -> Automatic Repair and repair the system.
Can you boot into advanced mode, go to Command Prompt and then type the following commands, then do a reboot and test.
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
Disconnect all external devices connected to it.

Hi, I am totally not a computer genius so I have to ask this question, how do I get by the blue screen of death to do these fixes?
I’d like to update my guide with your fix. How did you conclude that you needed to hide / uninstall an update? If you can send me a detailed guide, that will be helpful.
I actually found a fix somewhere else where it instructed me to download this windows 10 windows update-picker, where you can pick and choose which update you want. It was developed by Microsoft. It’s funny that this feature is just some third-party download that is not included build in to windows 10. This add-on for windows update just helped me a lot. What a nonsense from Microsoft as if they realised their fault later on.
I tried fixing this error by booting by disabling driver signature enforcement and it didnt work. Booting in safe mode does not work and spits out the same error code. I tried working in console with sfc.exe /scannow but I keep getting the same output: “Windows … could not perform the operation …”
I am running Windows 10 and during a system update, everything went wrong. My pc is custom- built with the ASRock BIOS.
The Win 10 key is in your bios, just install win10 from the free official microsoft ISO and you’ll see your Windows will be activated.
Reboot and interrupt 3 times, at the logo screen.
Make sure no external devices/usbs are connected.
I used to be able to reach the advanced options and troubleshooting page. As of later today I am now stuck on a black screen after the windows logo with the words under it
Which screen are you able to reach?
Will the first solution delete all files or kep them?
Go to bios, and reset it to defaults. Then try reinstalling via USB.
when i go for sfc scan gives me a message system repair pending to go back restart and run sfc again. the keyboard works now and accepts text in command prompt. need to recover the system urgent. I tried to reinstall windows from installation CD but it doesnt go to the mode as keyboard now aagain doesnt respond. it responded only in command prompt. pl help

my keyboard doesnt seem to function and i am unable to select f7 from startup settings. pl require urgent help
Hiya. First off, thank you for providing detailed, concise info on how to deal with this problem.
I’m trying to install my OS on a new laptop. For testing, the company put a temporary version of Win 10 on there and i’m trying to format the drive and install my own version on it.
I’ve got an official, verified version of Win 10. When i tell the laptop to boot from the CD drive i get about 10 seconds of the buffering sign, followed by the BSOD and the message “Your PC ran into a problem and needs to restart.” It then gets caught in a restart loop until i just let it go to the test version of Win.
I tried restarting it with the driver signature enforcement disabled but i get the option to boot from the disk before it gives me a chance to disable that particular thing so i’m not sure how to disable that before attempting the install.
I’ve also ran an SFC scan, although when i try to look at the .txt log for the scan it’s just an empty notepad file. And when i attempt to repair the corrupt system files i get the following:
“Error: 87
The online/cleanup-image/restorehealth option is unknown.
For more information, refer to the help by running DISM.exe/?.
The DISM log file can be found at C:WINDOWSLOGSDISMdism.log”
However the second time i ran the SFC scan i got the message: “Windows Resource Protection did not find any integrity violations”
I then restarted and tried to install from the disc but got the bsod with the same error.
Can you offer any advice on how to do clean install please? Kind of at my wits end with this.
Thanks in advance
