Windows 10 Upgrade problem "We couldn't update the system reserved partition"..

I have installed an original copy of Windows 8.1 Pro in my Teclast X98 Air 3G and try to upgrade to Windows 10 using the Windows Update feature, but everytime I try it, it returns the error "We couldn't update the system reserved partition". I increased the System Reserved partition size to 500MB as Windows 10 need, but no luck.

Anyone have a solution to that problem?
