Task Sequence has failed with the error code 0x80070070

Recently I have encountered with several computers that failed during the task sequence deployment process, probably this issue is very common in many organizations, Before I show you the solution, let me show you the error message:


The solutions are:

Once you encounter the above error, please press F8 (hope you enabled it) and start with DISKPART commands:

List disk
Select disk X (default 0)


If you see that this issue is more than few computers it means that you have a wrong configuration in your TS, preheats that ” System reserved ” Drive is the default and the TS trying to download the image file on system reserved drive, (as you know, system reserved captaincy is 100MB…) goes over on your phrases and make sure the system reserved is no default one.
