Hello
I have Manjaro installed on my NVME SSD. On my 2nd SSD SATA internet hard drive, I have installed Batocera (a Linux distribution for retro-gaming). When I boot up, I get to the Linux grub, but it doesn’t offer me the 2nd hard drive. Bootable USB keys are not detected/proposed either. I know that in dual-boot with disk partitioning it is ok (I have this configuration on another computer with a Windows/Linux dual-boot on the same internal SSD).
So my question is : is it possible during a boot to choose on which hard disk to boot, without having to go through the BIOS/UEFI each time ? Grub only detects the partitions of the drive it is installed on? Not the other physical medias?
Thanks
