A minimal search and reading would be enough to understand the problem.

Memtest86+ v4.20 is for BIOS (and/or CSM) only, not for UEFI.

memdisk (as of version 6.04-pre1) is for BIOS (and/or CSM) only, not
for UEFI.
So, for UEFI boot, you need tools/kernels that are compatible with
UEFI.
BTW, some EFI binaries are compatible with Secure Boot, and some are
not - syslinux.efi 6.04-pre1 is/are in the latter group.
