Task Sequence Fail on Computer Rebuild

The following instructions can be used when you are trying, and failing, to rebuild a machine by booting it from a cd/usb stick and then pushing a Task Sequence down from SCCM. In this case the machine is refusing to acknowledge the existence of said Task Sequence.

Although this very rarely solves any major issues you may be having, it can be worth a shot once you've exhausted all the usual routes.

If the machine is refusing to find the Task Sequence on the network and kicking back a Task Sequence Not Found/Located message, there's an outside chance it could be because some remnant of the old system is screwing things up. As such we need to wipe the hard drive of the machine.

At the point where the failure message pops up, do the following:
 
Press F8

Type Diskpart at the dos prompt 

Then type Select Disk 0

Then type Clean

Then type Exit

 

Once this is done you can restart. Congratulations, you now stand a slightly improved chance of the machine picking up the Task Sequence from SCCM.
