Install from a partition

Is there a way of installing from a partition instead of a CD.???
I mean I have the contents of the CD in /dev/hd1 and I want to install it in
/dev/hd0.
Is there a way of breaking the installation floppy process and tell it not
to use /dev/cdrom but /dev/hd1, or make a link to /dev/hd1 and call it
/dev/cdrom ???

maybe some way of getting a virtual terminal or something ???


thanx!
