How to EFI install Kali Linux (Beginner Ways)

[Make Kali Great Again]

you should download kali weekly image

What should I do with the legacy Kali OS on my hard drive (that works only under Legacy)? Should I delete the legacy Kali OS or just format the partitions containing it to make way for the new uefi weekly kali install? What's the best way to delete Legacy Kali OS that's on my hard drive?

You don't have to erase it if you have already installed. Just install grub in your EFI partition because UEFI reads from EFI boot sector. Boot into kali-live (in legacy or in UEFI doesn't matter but if you boot kali live in UEFI again that problem efi boot files are required). Run these commands after booting kali-live:

sudo mount /dev/sda* /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo mount /dev/sda** /mnt/boot/efi
sudo chroot /mnt
grub-install /dev/sda
exit
sudo umount /mnt/dev
sudo umount /mnt/proc
sudo umount /mnt/sys
sudo umount /mnt/boot/efi
sudo umount /mnt

Replace * in sudo mount /dev/sda* /mnt with your linux partition assigned value. Like mine is /dev/sda5
Replace ** in sudo mount /dev/sda** /mnt/boot/efi with your EFI partition assigned value. Mine is /dev/sda1
Use fdisk -l to list all partitions.

Then switch to UEFI after installation of grub.

Under disk management in Windows I can see an EFI partition. This was factory shipped as EFI Partition. You mean the code you supplied will install Grub there? Will it be Grub 1 or 2 that's going to install? What should I do with the Grub that was installed on my MBR when I did the legacy install prior? Delete it?

I log in with my username and password and then type those commands you provided in terminal?

Yeah, grub2 will be installed in EFI partition. You can delete the MBR once you install grub. Grub1 became obsolete long ago before kali rolling was released.

Don't login to your kali. Disable Legacy BIOS and Secure BOOT and boot kali live from bootable USB and then run those commands.

If I disable legacy bios and use uefi it won't read the Live Kali CD. I'm forced to use Legacy

and boot kali live from bootable USB

I'm using a Live Kali CD

and then run those commands.

Run those commands when I get into terminal inside the Live Kali CD?

Replace * in sudo mount /dev/sda* /mnt with your linux partition assigned value. Like mine is /dev/sda5

I have a few linux partitions I created, which one? I have : /dev/sda5 root /dev/sda6 boot /dev/sda 8 home /dev/sda 9 opt

[B]sudo mount /dev/sda* /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys

Is there a space before and after --bind?

grub-install /dev/sda

Do I need to be connected online to internet for this bit?
Prior to this I already had Kali installed on my hard drive.

[B]sudo mount /dev/sda* /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo mount /dev/sda** /mnt/boot/efi
sudo chroot /mnt
grub-install /dev/sda

After this I got:
Installing for i386-pc platform
grub-install warning: This GPT partition label contains no BIOS Boot Partition, embedding won't be possible.
grub-install warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are Unreliable and their use is discouraged.
grub-install error: will not proceed with blocklists
