I'm currently running CentOS-7, but I'd like to re-boot into CentOS-6.5 which I have on another partition. Although this OS is in the grub list when I boot, if I try to run it I get a segfault. I guess this is something to do with the change from grub to grub2? In any case, I'm wondering if there is any simple way of booting into both CentOS-6 and CentOS-7? -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin
