Windows 10 2004 Update fails to install with error 0xc0000005

My bcd file was missing the device info

Run bcdedit and see if the device info is missing

I ran  bcdedit /set {bootmgr} device partition=C:   command prompt in admin mode and it fixed the problem

Finally !!!! I tried for weeks to upgrade to v 2004, but never was able too! From error code 0xc0000005 to .....0xc1900101, nothing worked!

I never had any problems from 1803 to 1909, but 2004 (ever since it came up as a feature update) never worked!

Until now....I ran  bcdedit /set {bootmgr} device partition=C:   command prompt in admin mode and it fixed the problem !!! 

Thank you fdsonn !!!

Hi wo747.

I have the same issue and I can see that you resolved yours by checking bcedit to see if { bootmgr} device partition was set to C:

I have checked mine in command promt also and my device partition is already set to C:

Did you have to do anything else other than add that command?

Thanks

Rich

Hi Rich,

Run " bcdedit /set {bootmgr} device partition=C: "   command prompt in admin mode again, as mine was also already set for C:

I also Disabled the Build-in Administrator (make sure your user name has Administrator privilege)

Enable Built-in Administrator from Command Prompt (Windows 10 Home)

The command line can also be used to enable and disable the administrator account.

Open Start, type: CMD, right-click Command Prompt then click Run as administrator.

Type the following command and press Enter:

net user administrator /active:yes

To disable it, type the following command and press Enter:

Disabling it is just as easy, type net user administrator /active:no

I hope this works for you!

Tried both methods both failed the same way.
