Description of problem:

F18a tc6, there is no "use free space" option, so by default fedora erases the "other os" even if there is free space.


Version-Release number of selected component (if applicable):
F18a TC6

How reproducible:
always

Steps to Reproduce:
1. xp installed on a partition, free space (unpartitioned) avaiable for fedora 
2. use automatic partitioning (there is no option)
3. after setup, there is only fedora on the guest hard disk.
  
Actual results:
data loss (unwanted and forceful alternate os deletion by anaconda)


Expected results:
there should be an "use free space" option, like previous releases.

Additional info:
In text mode there is such an option, but i did not test it yet.
