Installation of AsteriskNow

Hi there, Merry Xmas

I´m new into Linux and Asterisk!!!

I have a Dell Dimension with Fedora 6 installed already, I downloaded AsteriskNow and burn the Cd, installation started ok, until it promted that need to erase the existing partition. Then I went into Custom Installation to try to make a new partition, with Disk druid, then thing is, maybe because I don´t know about linux folders and partitions, it didn´t alow me to reduce the size of the actual partition where Fedora is to create a new one for AsteriskNow, as the Fedora partition is occupying all disk space.
I read that AsteriskNow has to be on the root, I supose that´s the \ symbol, is it possible that Fedora is there and Asterisk too?

Thanks in advance
