Here is the dual boot page that you may want to read through it has a lot of good info.
https://help.ubuntu.com/community/WindowsDualBoot
I'm not exactly sure what your asking.
if you want to know how to partition your drive here's a good example.

Allow 250 gb or more for your windows 7 install
with the other 250 partition it like this

/ (root Partition) 20 gbs
/swap 2 gbs
/home rest of drive.

NOTE:: BACK UP any important files before partitioning!

you can do this in Ubuntu installer when it get to the partition stage by clicking on something else.
Good luck

You only need one swap partition. If you have 3GB or more of RAM and do not hibernate you can make swap 2GB otherwise the size of RAM in GiB or a bit more than GB.

kc1di gave a good suggestion on partitioning, they all can be logical with Ubuntu inside one primary partition.

Most laptops use all four primary partitions. Post this to see current partitions from a terminal from liveCD or USB or post screenshot from gparted from liveCD and use paperclip icon in edit panel above to attach to your message.


sudo fdisk -lu

@ Dr. div11

If you run the command line suggested by oldfred and post the output in a reply, or attach a screenshot from gparted when the computer is booted from a liveCD, it will be easier to help you. Otherwise we know too little to really help you.

/swap 2 gbs
/home rest of drive.

How about moving the swap partition in front of the root partition. The beginning of a drive is faster and you minimize head movements between swap and the root partition (that contains the binaries). ):P

Hi

This is what I did to dual boot, use it as a starting point. You should change this depending on your need.

100 MB windows reserve (automatically created at the time of win install)*
50 GB NTFS Windows install
06 GB SWAP space
15 GB / EXT 4-- Ubuntu Install
400+ GB (rest of the HD) NTFS partition for shared data between the two os.

* Install win first to make the dual boot set-up easy.



Hope this helps.
Cheers,
