    That FAT32 partition was originally ment for the EFI, but then I decided to use legacy BIOS for support for older PCs as I connect my drive to a lot of various computers. But I am no professional and don't know the advantages / disadvantages. Is it worth to switch to EFI and is it even possible?

    Exactly which Grub version is installed in TW on the internal disk? As arvidjaar wrote, a UUID can't be read from a filesystem it doesn't understand. Grub Legacy cannot handle EXT4 partitions formatted with the 64bit option that's been default since ~26 months ago.

    Something to test: substitute /dev/sdb5 for the UUID=<blah...> string in the first disk's Grub stanza.
    Reg. Linux User #211409 *** multibooting since 1992
    Primary: 42.3,TW,15.0 & 13.1 on Haswell w/ RAID
    Secondary: eComStation (OS/2)&42.3 on 965P/Radeon
    Tertiary: TW,15.0,42.3,Fedora,Debian,more on Kaby Lake,Q45,Q43,G41,G3X,965G,Cedar,Caicos,Oland,GT218&&&

    What do you mean by that? I tried to google translate the word "stanza", but I don't think I got what you ment... Is GRUB composing poetry now? I am confused.

    Code:
    menuentry 'TW' {
        set root=(blah)
        more blah
        even more blah
        blah blah blah blah
        linux /boot/vmlinuz blah UUID^H^H^H^Hroot=/dev/sdb5 blah
        initrd /boot/initrd...
    }
    Everything in the code block comprises one stanza.
