I've a multiboot Win7/Ubuntu laptop. Looking at the /dev/sda in Gparted
Note sure if this will help, but I see the following:

Partition	File System	Mount Point	Label	 Size	Flags
unallocated	unallocated				 1.00MiB
/dev/sda1	ntfs				SYSTEM	 66.59Mib boot
/dev/sda2	ntfs				Win7	 46.40Gib
/dev/sda4	extended				 188.33Gib
 /dev/sda5	ext4				karmic	 157.91Gib
 /dev/sda7	ext4		/		lucid	 24.86Gib
 /dev/sda6	linux-swap				 5.56Gib
/dev/sda3	ntfs				RECOVERY 11.91Gib
unallocated						 1.31Mib

Note: I skipped the Used and Unused columns.
