Hi,
Is there a simple and safe manual on how to install Ubuntu 14 on machine with RedHat 7.2 as dual boot?
thanks in advance on your help.

I believe Redhat normally uses LVM. Is that how you have installed?

If so probably better to install to another logical volume. Ubuntu normal install is just to a partition. And its default LVM install erases entire drive.
You still should be able to use Something Else, but I do not know LVM.

sudo parted -l
