Hi, I have a laptop with 2 hard drives. The first has Fedora 20 (no windows or anything else) and the second is unused. I would like to install CentOS7 on the unused drive so I can dual boot with the choice of the 2 OS's on the Grub menu. I am comfortable in partitioning drives and installing Linux distributions. I am afraid I may mess up the MBR and/or set up Grub incorrectly so I lose everything. Please point me to some documentation to help me. Thank you, Joe _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
