Windows 10 not booting and showing a black screen

Many users are also reporting the same, one thought is that the user profile has become corrupt & the solution is to create a new one within cmd prompt under task manager.

From the black screen press ctrl alt del to open task manager -> file -> run new task

type "cmd.exe" without quotes, and check the admin privileges box.

in cmd:

type:

net user /add [username] [password]

username and password without []

press enter, then type:

net localgroup administrators [username] /add

Hi Ben. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

Here are steps to recover from failed Updates or Version Update install which causes Windows to fail to start:

1. Try whichever method works here to get into Advanced Startup Options to run System Restore if this is a Windows Update, or Go Back to Old Version if this is a version update. https://www.tenforums.com/tutorials/2294-advanc.... Easiest is to restart or force shutdown the PC 3 times.

If you are able to access System Restore or Go Back and it fails, skip to step 3.

2. If necessary create bootable installation media to access the repair options if not accessible by any other method: http://windows.microsoft.com/en-us/windows-10/m...

Boot media by powering up the PC while pressing the BIOS Boot Menu Key: https://www.sysnative.com/forums/hardware-tutor...

You may need to enter BIOS/UEFI Setup to turn off Fast Boot if it won't allow the Boot Menu key to interrupt starting Windows: https://www.mydigitallife.net/comprehensive-lis...

Choose UEFI version of media if offered, browse to second screen to Repair Your Computer link, then Advanced Troubleshoot options to run System Restore to a point before the problem began, or choose More Options to Go Back to Old Version if this was a version Update.

If it rolls back then you can hide the Windows Updates and Version Upgrade responsible until they mature by installing and running immediately the Hide Updates tool: https://www.howtogeek.com/224471/how-to-prevent...

3. If this fails try a Startup Repair, or go back to Troubleshoot Options on the previous screen to Reset your PC which will save your files while reinstalling Windows.
4. If that fails you can use the booted media to Clean Install the latest version which should get you past all difficulties as it has hundreds of thousands of others who have followed the steps in this link and never come back to report another problem: http://answers.microsoft.com/en-us/windows/wiki... The link compiles the best possible install of Windows 10 that will stay that way as long as you stick with the tools and methods given.

There is a step to rescue files from the same bootable media: http://answers.microsoft.com/en-us/windows/wiki...

Once you're back in Windows 10, you can block the problem Windows or Version Update using one of these methods: https://www.howtogeek.com/224471/how-to-prevent...

Feel free to ask back any questions and let us know how it goes. I'll keep working with you until it's resolved.

Power on and off your computer three times

How do you do that?

Power on, when you see the Windows Logo - power off

Power on, when you see the Windows Logo - power off

Power on, it will then your computer will boot into the Advanced Recovery environment

You might be asked to sign in with your Microsoft Account or Local Account password.

Click Advanced Options

Click Troubleshoot

Click Advanced Options

Click System Restore, see if you can go back to an earlier time.

If not, boot into the recovery environment again, then try performing a startup repair.

If that does not work, boot into the recovery environment, then click 'Go back to previous version of Windows'

If that does not work.

Go to a working computer, download, create a bootable copy, then perform a clean install.

My apologies I didn’t realise you couldn’t boot at all.

Can you access another PC to download the media creation tool or do you have access to one?

If you do then you can try fixing the boot from that.

After booting into setup, choose the Repair Computer option > Troubleshoot > Advanced Options > Command Prompt. If you are using a recovery drive, click Troubleshoot > Advanced Options > Command Prompt.

Once you have the command prompt up on screen, you will need to issue a set of commands to find and resolve issues that might be preventing your computer from booting.

Type BOOTREC /FIXMBR and hit <Enter>.

This command will attempt to fix any corruption issues with the master boot record.

If all goes well, you should see The operation completed successfully.

Next, type BOOTREC /FIXBOOT then hit <Enter>.

This command will attempt to write a new boot sector on the hard disk if Windows detects damage. Usually, this happens in cases where an older version of Windows was installed, or a non-compatible operating system such as Linux was installed.

If you are seeing an error such as Boot Manager is Missing, then the BOOTREC /RebuildBcd command might be able to fix it. This operation can also restore boot entries for older versions of Windows if you have a dual boot configuration.

If BOOTREC /RebuildBcd does not work, then Microsoft recommends you back up your BCD (Boot Configuration Data) store, then run the BOOTREC /RebuildBcd command again. Here is how you do it.

Type each command then hit <Enter>:

bcdedit /export C:\BCD_Backup

c:

cd boot

attrib bcd -s -h -r

ren c:\boot\bcd bcd.old

bootrec /RebuildBcd

Another option if you are dual booting with older versions of Windows such as Windows 7 is the BOOTREC /ScanOs command. The ScanOS command can find and restore entries for older versions of Windows.

I hope this helps.
