My 32GB tablet happens to be an Asus T100 but I opted for the keyboard which has the 500GB HDD in it. So I was able to take the upgrade.
In your case, you should take it to the Microsoft Store since they had an offer to upgrade or if they fail, a free laptop!
It's either that or the laptop maker has to tell how.
Upgrade note tells me I need 20 Gb space but I only have about 5 Gb available. This is an Acer One Cloudbook 11 with a 32 Gb eMMC ssd drive instead of a harddrive. How do I download the upgrade when I don't have enough room...about 5 Gb instead of 20 Gb. Can I work off a Flash Drive?
