Can't boot Ubuntu because Windows 10 rewrites entire EFI partition

I'm having trouble setting up a dual boot with Windows 10 and Ubuntu 16.04 (Game-pack) on an HP Pavilion Gaming Laptop (15 -cx0049nr).
I realize that many, many questions have been asked on this, but I have read dozens of threads and tried all sorts of solutions with no luck.
So far, I cleared space with the disk management tool, disabled fast boot, hibernation and secure boot and installed ubuntu with a liveUSB successfully.
Right after installation, I found that if I hit F9 right away while restarting, I get the boot device list, and can choose ubuntu. But if I don't hit F9, it goes straight to windows. At the next reboot, if I hit F9, the Ubuntu folder and all related .EFI files are gone.
Going back into Windows, the disk management utility shows the Ubuntu partition as unallocated space. Diskpart can't find it either. Exploring the EFI partition after mounting it with Diskpart confirms that the Ubuntu folder and all grub files are gone. It's like Windows has rewritten the EFI partition and refuses to acknowledge the Ubuntu partition.
So far, I have tried:
-loading the liveUSB and running boot repair- this allows me to get in with F9 at start as before, until the first time that Windows boots. (At this point, fdisk -l indicates that there is a discrepancy between primary and backup GPT partition tables. Gdisk can fix it, but it comes back every time.)
-Installing rEFInd, which can't find any Ubuntu EFI files
-Installing EasyUEFI, which also can't find any Ubuntu EFI files
-Creating a boot entry for Ubuntu with bcdedit, which persists through multiple boots, but points to nothing (Error code 0xc00000076)
I'm at a loss as to where to go next.
Please excuse the long post on a topic that has already been very well covered.
Thanks for your help!
