Ubuntu Or Linux Mint ISO with persistence in UEFI Secure Multi-Boot with Windows 10 x64 can be realised as follows:

 

- Download Make_Ext Or Download Easy2Boot

- In folder Easy2Boot_v1.A8\_ISO\docs\Make_Ext Run Make_Ext.exe

- Make Ext File with File name and Volume Name casper-rw with ext3 filesystem and size e.g. 1000 MB to be located in folder \images\ubuntu

- In Windows 10 x64  run WinNTSetup_x64.exe so that EFI partition is mounted as drive Z:

- use R-mouse menu to run as administrator Explorer-x64.exe of Explorer++

- edit file boot\grub\grub.cfg created earlier on EFI drive Z: and add the following entry

=

if [ -e "(hd0,gpt3)/images/ubuntu-18.10-desktop-amd64.iso" ]; then
menuentry "ISO Ubuntu - ubuntu-18.10-desktop-amd64.iso (hd0,gpt3) persistence" {
  set iso_path=/images/ubuntu-18.10-desktop-amd64.iso
  loopback loop (hd0,gpt3)$iso_path
  linux (loop)/casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper persistent persistent-path=/images/ubuntu/ iso-scan/filename=$iso_path quiet splash ---
  initrd (loop)/casper/initrd
}
fi
 

- Boot with Grub2 of Linux Mint and select the ISO Ubuntu - persistence menuentry
