On my laptop that uses UEFI to boot, I have Trisquel on one disk, and I tried to install Trisquel also on a second disk. However, after the install is finished and I reboot, in the UEFI menu, there is only one Trisquel and it boots to the Trisquel instaled on the second disk.

For some reason, the second install has created an EFI partition on the second disk, but it has used the EFI partition of the first disk, and it has created /boot/efi/EFI/trisquel/grubx64.efi, overriding the previous one. I chrooted in the original install of Trisquel, ran grub-update and this has overriden that file again, then after reboot, I still have a single Trisquel entry but it boots into Trisquel on the first disk.

Is there a way to make it so that I have an entry for each in the UEFI menu? I am guessing that the UEFI menu can only look into a single EFI partition, but would there be a way to make grub use a different name than Trisquel, so that the file in the EFI partition does not override the one from the other Trisquel? Of course, I’d like that the modified name persists in case of any later grub update.
