yeah, actually whenever a os boots it searches kernel for the OS. hence require a boot loader for it.
To use your stuff you have to install it on the system and for that first boot your system with a CD/DVD of that stuff and install it in another partition of the disk.
do the manual partition process at the momnet.

If your system doesn't have empty disk cylinders then it can be done by another tool (don't remember the name of that tool)
To understand this new OS better I will recommend you to use vmware first so that you don't lose your data on the system
