EFI boot on Lenovo Thinkcenter M92Z

# disable secure boot in the bios, in menu security

# downlad and unzip refind-bin-0.7.8.zip

# install refind, assuming your ESP partition is /dev/sda1 and mounted in /boot/efi
cd refind-bin-0.7.8
./install.sh

# type y and go ahead
# at that time your boot entry should look like that
Boot0000* rEFInd Boot Manager	HD(1,800,f3800,b500458e-3e0e-4299-bc41-48424508bced)File(\EFI\refind\refind_x64.efi)

# rename boot entry from refind to official EFI fallback filename, see http://www.rodsbooks.com/refind/installing.html#naming for reasons
./mvrefind.sh  /boot/efi/EFI/refind /boot/efi/EFI/BOOT

# notice the bootx64 file
efibootmgr --verbose | grep HD

Thanks a lot, this tip works nice too on a Apple Intel Mac Mini hardly converted to Debian.
I use the refind debian package instead of the zip.

Thanks, this allowed me to set up EFI boot with Debian on a 2017 Macbook Pro:

1. sudo apt-get install refind
2. sudo mvrefind /boot/efi/EFI/refind /boot/efi/EFI/BOOT
