[Major]

I Have made an unattended windows with setting to set manually the disk configurations, it worked fine But yesterday i wanted to create a partition in the options of the disk, the boton [New and extend] were grey (inactive). How can i do to set them active.Thanks.

Here is the part of my autounattended.xml regarding the disk

The New button is only available if there is enough space left on the disk to create a new partition. What size hard disk are you testing on?

Delete the 39.8 and then you will have new
