UEFI boot fails...

[Jacques Beigbeder]

Hello,

When booting a Dell computer, I get the prompt:
grub>

Just typing: source /efi/NAME/grub.cfg
make my computer boots.

My question: why /efi/NAME/grub.cfg is ignored?
I tried a lot of things:
* refreshing the setup
* refreshing /boot/efi with
	grub-install --target=x86_64-efi --efi-directory=/boot/efi --boot-directory=/boot --bootloader-id=NAME
* etc.

Thanks.
