Proxmox 5.2 not format bios boot (efi) partition

[fed]

hi

workaround on fresh install proxmox 5.2

install proxmox
reboot
boot from usb proxmox stick on "rescue boot"
im my case with mirror between 2 disk
mkfs.vfat /dev/sdX1
mkfs.vfat /dev/sdY1
for checking if everything is ok
mount /dev/sdX1 /boot/efi
grub-install /dev/sdX1
grub-install /dev/sdY1
reboot
remove usb stick
ok

regards

Is it still the case on 5.3? I'm having problems booting form m.2 nvme drive (pve not found), hence, I'm trying to narrow it down either to bios-related issue or partitioning.
