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):
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.
data loss (unwanted and forceful alternate os deletion by anaconda)
there should be an "use free space" option, like previous releases.
In text mode there is such an option, but i did not test it yet.
