Define what YOU mean by "carve out" and by "free space". If you mean unused
space within a partition, the answer is No, Vista Setup cannot create a new
partition within an existing partition. But if you mean that you have
unallocated space outside your existing single partition, then the answer is
Yes, Vista Setup can create a partition in that unallocated space, then
format it and install Vista there.
In WinXP, run Disk Management (diskmgmt.msc) to see if the Graphical View
shows any Unallocated Space (with a GREEN bar over it). If you have at
least 15 GB (20 GB would be much better), then Vista Setup can create a new
partition there. (I'm using Vista and its Disk Management uses the term
"Free Space" twice on the one page - and the term means something different
each time. :>( In the Volume List, the "Free Space" column means unused
space within a volume. In the Graphical View, "Free Space" means
unallocated space outside any partition. I no longer dual-boot WinXP, and I
don't recall the exact terms it uses.)
Vista has added some tools to Disk Management, including Shrink Volume.
Once you get Vista installed, you can use DM to shrink an existing
partition. So if you have a 100 GB HD, all in a single partition, but you
are using only 60 GB of the space in that 100 GB partition, you can use DM
to Shrink that partition by 40 GB, then create a new partition in the
vacated space. But you can't do that during Vista installation. And
WinXP's DM can't shrink an existing volume.
Since you seem to be an experienced user, you might want to check out the
DiskPart.exe shell. (It's NOT the same as the DiskPart command in the
Recovery Console!) This is a powerful tool and it can do a lot of damage,
so be careful. In Vista, DiskPart can do even more than Disk Management,
including Shrink Volume, but I don't think that WinXP's version was updated
to include this command.
