Scott pointed out that EFI does not have 4 partition limit. So I went ahead and resized. Win10 still worked. Then tried Linux Mint install (live USB works fine). Made main and swap partitions as sda5 and sda6. But on restart got Secure Boot Violation. Tried again, watching progress, and GRUB install crashed. Win10 still working, but it's disk management tool does NOT show the sda5 or sda6, and Win10 partition still original size. Also gparted gives libparted warning: The driver descriptor says the block size is 2048 bytes, but linux says it is 512 bytes. Wondering if I need to turn off secure boot and allow Linux to install 3rd party drivers, but I rather would like to avoid that. Ideas?

It knows how to shrink the windows filesystem and set up the partitions. Then install Mint on the Ubuntu partition.
