Task sequence error 0x80070070

Task Sequence: <Task_Sequence_Name> has failed with the error code (0x80070070). For more information, please contact your system administrator or helpdesk operator.

I have received the above error just before copying/staging the boot media, when I have tried to deploy Windows 7 image using deploy task sequence.  I am sure I have enough space on the local drive but seems to be an issue copying the WinPE image to C drive.

To resolve the issue, hit F8 to open the command prompt in winPE. Then run DiskPart, then List Disk, then Select disk 0, then clean

Restart the target machine and try again. This time it should work without task sequence error 0x80070070.


  1. How can this step be automated, especially if you want ZeroTouch?

  2. Normally you wont get this problem if you are using PxE boot or create the boot disk using the same boot image assigned to task sequence which you will be using.

    You may get this error only when you are using the boot media created using different boot image which is not assigned to the task sequence you will be running. Hope this helps.
