Another error which I just ran into whilst on my OSD travels.
I came across this:
It seems that the Referenced machine is locked to that OS
So a simple fix can be done to achieve a successful OSD (with the help of some research)
If you open command prompt during your Task Sequence (F8) this needs to be enabled on the boot image before – otherwise it won’t work.
Once command prompt is opened – run the following commands – one after another
sel disk 0
sel par 1
cre par pri
format fs=ntfs quick
Reboot the referenced machine, and restart the Task SequenceFollow @CraigCloudITPro
