Set BIOS as UEFI, but set Secure Boot as Disabled.

1. Boot Slackware disk. Use cfdisk, choose GPT and create at least (in order):
1 partition, 500M, EFI System type
1 partition, 4G, Linux Swap
1 partition, whole disk, Linux filesystem


Of course, you can continue adding /usr, /var a.s.o. as different partitions.


Now, start setup.



2. Format Swap, Format / in 3rd partition above as EXT4.

When finish, Slack will ask to format the EFI partition. Agree, it will mount it as /boot/efi.



3. Install as usual





When setup reaches the LILO install on MBR, will asks to start ELILO instead. Choose YES
On next screen, choose Don''t install ELILO



5. Continue install as usual



6. When setup is done, choose not to reboot but to open a shell



7. Run


chroot /mnt /bin/bash
source /etc/profile
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=grub 
grub-mkconfig -o /boot/grub/grub.cfg
mkdir -p /boot/efi/EFI/boot
cp /boot/efi/EFI/grub/grubx64.efi /boot/efi/EFI/boot/bootx64.efi
