It just depend how did you configure your Live Linux on your USB stick (should be MBR partition header, and probably USB stick should be formatted as ext4 or NTFS). Please, look here: https://rufus.akeo.ie/ . Please, note that on this figure: https://rufus.akeo.ie/pics/rufus_en.png partition scheme should be only MBR, and File System I use in legacy case is NOT FAT32, NTFS usually (maybe ext2 or ext4). Under these conditions, USB should show to you GRUB2 setup screen (my best guess).
