Need help with dual boot install

[JaimyvS]

I downloaded Backtrack 4 Final and burned it to a disc an booted it but when i have to choose how i want to install it, it only gave me two options

i want to install Backtrack on my C disk (here /dev/sda2) but i only want to install it on the free space and not the whole disk. So i thought i should choose Manual but then it says

I've got no idea what to choose from, i want it to be like when you install ubuntu and it's installed on a disk an i get an option when i start my computer if that's possible.

Well you have to know at least witch partition you want it on. Once you figured it out let me now so I can help.

You can only have 4 primary partitions. It looks like you already have 4 so BT4 can't create the partitions it needs. try the install again with 3 partitions

Thanks for your answer, i'll try to use my last partition for it.

Yeah, with 4 primary partitions, there's not much backtrack can do. I would see if you can delete one of the primaries (maybe a recovery partition or something that comes by default), and then try again. Gparted is a nice, easy tool to use, and several simple live CDs (SystemRescueCD, PartedMagic among others) exist to aid you in this task.

Well, you still can use one of this four partitions as long as you don't mind to loose all stuff you have got on that partition unless you go back to Windows and copy everything over.
Also make sure you do not mess with partition containing Windows or any Recovery partition.
But i would likely merge two partitions and then created extended partition where i would install BT.
