Hi
Sorry for my english.
I remove the recovery partition plus the android partitions, i only have now UEFI partition + windows partition. What I have done is to reinstall Windows 8.1 from a clean original windows 8.1 32 bits ISO, NO CHUWI ISOs, with rufus i prepared the iso to boot from USB. During installation i removed all partitions except the UEFI partition , and I select all the UNALLOCATED (important UNALLOCATED, don,t create manually a partition, let windows create the partitions that need for boot) space for the installation of windows. It worked in my case without problems (you must reinstall the drivers later of install windows). Later i updated to windows 10, once it was autimatically activated i generated a clean ISO with the microsoft media creation, prepared the iso file with rufus to boot form USB, and done a clean install of windows 10 in the same way, reinstall chuwi drivers and all perfect
