There isn't really an "optimal".  You obviously want to be comfortably over the minimum requirements, but other than that, its really only about what you want to do with them. I only use 10 GB for my Ubuntu partition, which is more than enough for me. The Windows partition is where I store most of stuff.

Thanks very well.

Yeah, I use 10 for Linux too. Anyway, here's my recommendation:

Divide into 3 partitions:
C:\ 40 GB for installing Windows
D:\ 100 GB NTFS for storing your data
Unpartitioned space 20 GB, for installing Linux

Install Windows in C and use D for storing all your data. That takes up 140 GB, leaving you with 20 GB of unpartitioned space. I suggest you leave this space unpartitioned because it'll make it easier to install your Linux OS (there's normally an option to "Install the OS in unpartioned space").

Of course, when I say 40GB, 100GB and 20GB, I don't mean it exactly. Use 35-36GB for C, 95-96 GB for D. This is because you will have less than 160 GB (My 500 GB hard disk has only 475 GB of usable space)

EDIT: Of course, I don't you need 20 GB for your Linux OS, because you can view and write to NTFS partitions from most Linux based distros, letting you use that space for storing data.
