I got a new computer and wanted to backup my drive right away. So it’s so far never been hooked up to the internet. No third part software added. It does have trial mcaffee installed.
I was receiving this error as well “Failed to get an exclusive lock on EFI system 0x8078011E Access Denied 0x80070005”
I got it to work by disabling the mcaffee realtime protection. It is currently proceeding backup, so far I’m further than I originally got.
After this I’m going to install Macrium Reflect (downloaded from another computer) and do another backup via the third party Macrium backup software.
Probably to restore the Windows 10 image at some point in the future I’ll have to disable my real time protection again – if I’m still using Mcaffee – not sure yet.

..additional info to above. Additional
So I didn’t modify any registry values or anything just went into the Mcaffee software and turned off realtime protection. There was a solution to turn off windows bit defender by modifying the DWORD start value in the registry from 2 (mine was 3) to 4 under HKEY_Local_Machine\System\CurrentControlSet\Services\SecurityHealthService under Start. I DID NOT go that route after I decided to try turning off the realtime protection first (then I enabled it to start the service again after a computer restart) .. my backup appears to be proceeding without errors. Backing up about 56Gb’s of data to an external drive, so far it’s been 20 minutes probably will take a couple hours.
