Fedora labels the partitions /USR, /HOME, etc. depending on how you partitioned it. If CentOS labeled them the same way (I guess it depends on what was installed where and when), then it might find the wrong one and boot a partition you weren't expecting. I learned this recently when I cloned my Fedora hard drive and it kept booting the old installation on a disk further down in the boot order. Dan
