Hello,

after having unsuccesfully tried several ways to install trisquel on an efi system, I come here to get some help. I successfully booted and installed trisquel about ten times, always with the same issue : grub can't install because it "can't get the canonical path of'cow'". I am aware that some operations must be done when booting (checking whether it is legacy boot or efi boot) and that a GPT partition table with a bios-grub partition must be created before installation in case of a legacy grub install. I tried but am not sure if it was really succesful, because my HDD still can't be selected to boot in the Bios :

The PC is an Asus R900V with an internal hard drive recognized by the BIOS under Sata devices on port 0. Works perfectly when I work with it on a live system, but can't select it on the Boot device priority option. Here is only listed the DVD drive or the USB flash drive when I put one.

Here comes the question : can the HDD absence from boot options be due to a wrong grub install ? And also : can someone explain me the easiest and most reliable way to install trisquel on this computer (I mean EFI vs Legacy boot)?
