I have EOS as my primary system running on my internal SSD. GRUB is the bootloader. If I were to insert a usb flash drive with another linux distro, for example Mint LMDE, the GRUB installed with EOS does not recognize the OS on the Flash drive.
Is there a way in which the boot loader can detect and identify OS installed on a flash drive connected to the USB board? If it is not possible with GRUB will it be possible with systemd-boot or some other boot loader?
