partitioning

While performing a Ubuntu 10.10 installation on my laptop, it doesn't show partitions pertaining to the PC.

My PC configuration is as follows :

HP Pavilion dv6 - 2020AX
AMD Turion II Dual Core Mobile Processor M500
4 GB RAM
OS Installed : Windows 7
500 GB Hard drive partitioned as follows :
- C : 227 GB (Free : 142 GB)
- D : 11.9 GB (Free : 1.98 GB) - Recovery
- F : 174 GB (Free : 18 GB)
- G : 50.5 GB (Free : 50.4 GB)

So, I want to perform a Dual-boot installation on my PC, so that Ubuntu resides in the free disk space G:. Therefore, I started the Ubuntu 10.10 installation and select the manual partitioning feature in the installation.

However, in the 'Allocate Drive Space' section of the installation, following partitions information is displayed:

Partition Type Size Used
/dev/sda
- /dev/sda1 1 MB unknown
- /dev/sda2 ntfs 208 MB unknown
- /dev/sda3 ntfs 244813 MB 168540 MB
- /dev/sda4 ntfs 255083 MB 3221 MB

where /dev/sda - 500 GB

So, what exactly is the problem? What is it should I do to install Ubuntu 10.10 in the G: disk space? Why are the partitions not being shown as the way they should be?

Any Suggestions. Thank you for the help.
