Installation fails with “failed to set new efi boot target”

Hi Fellow qubers

I’m having a problem with installation.

ISO is latest 4.0.3

At first gui installer would not start with kernel panic, I got around
this with adding:

Boot with — efi=no-rs

My next problem is when the install reaches “Installing boot loader” it
instantly fails with “failed to set new efi boot target”.

I tried hacking it with booting into a arch live iso and executing the
equivalent of:
——–
# mount the installation at /mnt
sudo mount /dev/sda3 /mnt # sda3 is root partition
sudo mount /dev/sda1 /mnt/boot/efi # sda1 is efi partition

# change the root to /mnt
sudo chroot /mnt

# create grub2 configuration
sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

sudo reboot
——–

However after I chroot I have no grub2 programs.

I am now at a loss.

Any help would be greatly appreciated.

Cheers
