I have to confess that on using another USB stick,
re-formating it under Windows-7, creating partitions with fdisk,
and running "sudo grub2-install /dev/sdc",
the USB stick did boot my CentOS-7 machine into its usual system.
I checked the first 4 x 512 bytes on the two sticks,
and they did differ in the first 512 bytes,
but I haven't analyzed the difference.
