Cannot use internal memory partition in my Nextbook 7 16GB tab

I have just purchased a Nextbook 7 16 gb tab. I have installed only a few apps and then got the message of "Insufficient Memory". I looked in the storage section and found the tab has TWO partitions under "Internal Storage" One has space of 0.98GB and another internal storage has 12.22GB. All my apps are installed in the first partition. How to use the larger partition for apps? So far I have been unable to do so. KINDLY HELP!!!
