Assunto: How to restore grub in UEFI mode

Hi, I recently upgrade my debian (UEFI) and grub is gone.. I try to recovery grub but failed or I`m doing something wrong.

This steps I following are:

-create usb with live cd

-change boot option to legacy mode and disable secure boot consequently

-boot from live cd (Here, when I boot from CD and check if i`m using EFI or legacy, always say legacy, maybe be here the problem)

-mount my partition / in /mnt

-install grub in /mnt

when install grub i receive the following message:

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.

 

Can someone help me?
