Success booting rEFInd!!!
Thanks you so much! And it appear that rEFInd also show LinuxMint
It seem after moving all rEFInd directory in and out without rEFInd on, I tried to clean the sda1 and sda3 up, then replace and rename refind_x64.efi to Microsoft/boot/bootmgfw.efi
After that, I boot my computer and see rEFInd on. It seem Sony have done something so that their system find only the bootloader residence inside /boot/Microsoft
rEFind successfully boot Linuxmint, but I would like to ask you to guide me tidy things up a bit. It seems rEFInd boot the grub, then grub boot linuxmint
Best Regard!
LGV
