That is not a partition. You have crossed the 4 primary partition
limit (3 Primary and 1 extended partition in your system) for MBR
partitioning. So cfdisk shows that free space as unusable.

According to your system, (hd0,0) is correct. Can you try chainloader
(hd0,0)+1 instead of chainloader +1 . I use grub2 so I cant be of much
help here. I also use Archlinux x86_64. Best place to ask would be
#archlinux in irc freenode .

BTW https://wiki.archlinux.org/index.php/GRUB#Dual_booting_with_Windows
mentions

title Windows
rootnoverify (hd0,0)
makeactive #if you use Windows7 this line should be commented out
-----------> did you read this?
chainloader +1
