Thanks for your response.
It boots via BIOS, and in fact boots into CentOS-7/KDE on a USB stick
(that is how I installed CentOS-7), and into Fedora-21/KDE on a stick.

But it doesn't boot back into the CentOS-7 system that is normally running
if I say "sudo grub2-install /dev/sdc" (the USB stick is sdc).
It just comes up with the repeated "-",
which I take to mean it has found the boot-loader on the USB stick,
but has not found the kernel on /dev/sda6.
