What specifically do you get for installation options?

For those that don't understand that Win7 installs 3-4 partitions:

I've a multiboot Win7/Ubuntu laptop. Looking at the /dev/sda in Gparted
I see the following:

Partition	File System	Mount Point	Label	 Size	Flags
unallocated	unallocated				 1.00MiB
/dev/sda1	ntfs				SYSTEM	 199.00Mib boot
/dev/sda2	ntfs				Win7	 97.66Gib
/dev/sda4	extended				 188.33Gib
 /dev/sda5	ext4				lucidg	 157.91Gib
 /dev/sda7	ext4		/		lucid	 24.86Gib
 /dev/sda6	linux-swap				 5.56Gib
/dev/sda3	ntfs				RECOVERY 11.91Gib
unallocated						 1.31Mib

Note that sda1, sda2, sda3, and 'unallocated' are reserved by Win7.

sda1 is the boot partition
sda2 is the actual Win7 working partition
sda3 is the Win7 recovery partition
sda4 is an the extended partition
sda5 is the base Ubuntu install partition
sda6 is the linux swap partition
sda7 is the additional test linux partition

and perhaps you are counting the first unallocated partition as number 4?

In any event, provide the details of what options the install provides.
Be sure to boot the Win7 machine at least twice after resizing the Win7
partition. Also report what you see with the Disk Management utility.

If you've resized the Win7 partition to allow for 100Gb of disk space I
see no issue with using the manual install from the liveCD to install
into that space. However, provide answers to the above first & we'll go
from there. Again *do not delete* any other partitions.
