Windows 8 fresh install - too many partitions

[fyrekrig]

As my tablet only has 32GB of internal memory I wanted to install a Windows 8 version with smaller footprint.

So I made one with Winreducer 8.1 and deleted all partitions before install. Don't need the Windows 8 restor feature as I use Macrium backup and put the images on the
HDD in keyboard.

However how much I try three extra partitions are created which I am unable to delete. On a MBR install on a desktop computer you always have the option to expand the "System reserved" so all system files
are on one big partition. It seems this not possible on the Asus Transformer T200TA.

Is there any way to get rid of the three extra partition?
Is this specific to Asus Transformer ?

Partition details!
