I have one SSD and two NVME.
My old motherboard does not detect the NVME to boot it.
I tried to install the system and the boot in the NVME, but it was not detected by CLOVER (GitHub - CloverHackyColor/CloverBootloader: Bootloader for macOS, Windows and Linux in UEFI and in legacy mode).
I tried to install the system in the NVME and boot on USB Stick, but the GRUB accuses the “Unkown Filesystem”.
I tried to open the GRUB via the command line and when typing “blkid” or “ls -l”, NVME is not detected.
How can I install the boot on an external disk but load the system inside the NVME ?
