second distro install
 

I have read listings in here about using lvm and grub to install a second distro - ubuntu < for me. I searched on mandrake 10 and it has grub installed. I am a little lost, can I use mandrake control center console to input the codes?
When I start man10 there doesn't seem to be an alternative other than linux, floppy and couple of others from which to load. As in one thread I did burn a copy gparted/livecd, but will have to read the pages about it.
When searching for the /dev/hda - I only find hda0 0, to add second distro, I would need to establish another /dev/hda - 1,2,etc? Now the MBR - main boot record? that's where hda0 0 is right?
Others speak of creating hda6,7 - but if this one is starting at 0 wouldn't the logical next be hda1 or 2,3? < this reminds me of a gateway range from 192.168.1 to 152.
Only with your help and understanding will this make sense

Ditch the LVM if you want more distros. The idea of LVM is it manages/eats up all your hard disk space because you have given it the permission to do so.
