Good morning. I have same this issue, I have tried to disable secure boot already, try to repair boot in live mode, and trying to repair it, I still get this same error. I have checked and tried all tips I've found in this forum, but still having the issue. Someone could help me, please? Thanks
Your profile states you have "Lite" edition. So assume that was Z16.3 Lite.
So are you now trying to install Z17.1 Core in its place, or alongside another OS?
Which installation option did you choose?
Did you check the SHA256 of the downloaded .iso?
Can you take a look at the pre-installation advice here: Before you install
Did you check the SHA256 of the downloaded .iso?
Which USB creation tool did you use?
(Sorry for all these questions)
chroot /mnt/boot-sav/mmcblk2p2 efibootmgr -v before grub install
EFI variables are not supported on this system.

chroot /mnt/boot-sav/mmcblk2p2 grub-install --efi-directory=/boot/efi --target=x86_64-efi
Installing for x86_64-efi platform.
grub-install: warning: EFI variables cannot be set on this system.
grub-install: warning: You will have to complete the GRUB setup manually.
Installation finished. No error reported.
Error: no grub*.efi generated for Zorin OS 17.1
It appears as if your BIOS does not accept EFI / UEFI support. Can you recreate the installer with Unetbootin and try again?
The NVRam lock status - if you have a laptop with a removable battery: remove the battery and all power sources, hold the power button for a 10-30 seconds to release all the stored voltages in the board. If you have a CMOS battery with a laptop setup it's tricky but, that can be removed to help release the lock status too. Desktops are easy to get to but, laptops need a bit of work to access, sometimes.
