windows System image generation

Have had consistent problems with windows 10 system imaging. Goes through the whole process and at the very end gives an error screen.
Backup medium is Intel 234Gig SSD drive internal.
Found that you MUST alter permissions on your target drive or this error screen always appears. Remember that Administrators on windows 10 will not give you blanket privileges.

Hi Ed
You must first "Take Ownership" of the target backup drive or petition you are using for the image location
Do this by rt clicking on the drive and select properties
Select Security TAB and then select the "Advanced" tab toward the bottom. Adjacent the Owner: line, select Change. Under the "Select User and Group" window click on the "Advanced" tab and then the "Find Now" tab. Scroll down until you find your user name and select it.
I am assuming your user name is part of the Administrators group. Press OK and it will appear in the window. click OK again and it will replace the existing owner selection. You need to do this in order to select the users & groups to grant the appropriate permissions. Press OK and you will return to the Security tab screen with a list of the group & user names with their corresponding permissions for this area.
I selected the following by now pressing the "Edit" key and repeating the same procedure explained above.
Everyone
ALL APPLICATION PACKAGES
Authenticated Users
SYSTEM
Your User Name
Administrators
Users
Backup Operators
SERVICE

This list is a bit overkill, but I didn't know which area the image routine would trip on so I included all of them to be safe.
Select each name and assign full control to each one.
Hope this helps.
I don't know your level of expertise level with windows 10 permission assignments so I went into a little more detail ref my process.
I not only did this on the main route of the drive but also each sub folder listing below it just to ensure all permissions were intact.
