Hello, the error that you are getting occurs due to an error in the recovery partition. You will need to create a media creation tool and boot into the USB media to repair this problem. You can learn to create the media creation USB here:

For the tutorial on how you can fix the partition, check this link out:

(NOTE that this link is for Windows 7, however the procedures you will need to follow are almost identical to Windows 10.)

Hope this helps, and let me know if you have further questions! :-)

Hi LRB. I'm Greg, an installation specialist and 9 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...

Make sure during the booted install to follow the illustrated steps to delete all partitions down to Unallocated Space to get it cleanest, then click Next to let it auto-create the needed partitions, format them and begin install - this makes it foolproof.

The media provided for the Clean Install is Version 1809 and normally the problems go away with the Clean Install, however if they don't you can find earlier version media to use here: https://tb.rg-adguard.net/public.php

Burn to DVD or create bootable 8+gb flash stick installer using this tool installed to Windows: https://www.microsoft.com/en-us/download/detail...

Then 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.
