[ale] GParted & unallocated space

I've seen people advocate with either choice for shrinking the windows
partition.  I just went through a similar situation where I wanted to
keep the Windows installation on a new laptop (Civ 5 ftw) and install
Archlinux to occupy half of the hard drive.  Unfortunately for me, the
archlinux installer didn't like the partition that windows had setup
as a result of the shrinking, something about cylinder boundaries and
such.  GParted wasn't working either, giving a similar message when I
tried to just give archlinux the large partition to work with.  One
challenge was all the partitions that Lenovo had in place (recovery,
installation, etc).  What I ended up having to do is manually
partition the unallocated space in GParted, and only make the
archlinux installer assign mount points, and it seemed fine with that.

As far as the space being unformatted, I think I ran into that
situation and got around it by formatting the partition as NTFS in
windows, and then simply reformatting once GParted was able to see it
upon reboot.
