That's definitely not the default behavior with the Fedora installer since Fedora 18.
With Fedora 17 and older, the default option was to replace existing Linux, and it was
plainly marked with other options described on the same window.
That I know of anyway, They are a 'write this to the
disk' system. It has been a long time but I (me!) do not know of a
Live-CD that does disk partitioning.
On Fedora, the same installer is used for live desktop and DVD installs. It has the same
partitioning functionality in either case.
The older installer for live installs was limited to rootfs being ext4 because the live
file system was imaged to the target partition or LV, and then resized as a post install
operation. That hasn't been the case since F18's installer, which uses rsync for
live installs, and will install to whatever file system and layout that the installer
supports (which is the same as for DVD and netinstall images).
Now you mentioned Windows. *If* you have Windows install you need to
'shrink' the Windows section and make a place for the Linux to be installed.
If you have Win 7 it has a disk partitioning program to do that
included. Else you will have to use something else.
Fedora 19 and 20 support [1] resizing NTFS volumes in both the guided and custom
partitioning paths. In Fedora 18 my recollection was that the guided path had no UI for
choosing how much to shrink the volume by. Whereas the UI in F19 and F20 is much more
obvious in the guided path, with a shrink button that reveals a slider to choose the
shrink amount.
In custom partitioning, when you click on the NTFS volume, there's no obvious UI for
resizing, but the volume size field can be edited. Click on that, and enter a smaller
value, and this will cause free space to be made available from which you can specify new
mount points for a new installation.
In all cases with the new installer UI, all layout changes merely create an edit list.
Nothing is changed on disk until you click the Begin Installation button from the hub (the
main menu).

[1] This is a best effort support case, as the installer doesn't actually do the
resizing, it's done via the NTFS-3G. But it is a test case for Fedora QA so it does
get some testing and ought to work.
