I have decided to install ubuntu. So I intend to install a dual-boot with Windows XP and Ubuntu 9.04. I currently have an old PC (AMD Athlon 1600 + / nVidia GeForce2 MX400 / 384 MB RAM) with a single DD 40 Go In addition to this, I intend to buy an external SD 80-100. My 2nd DD must serve me to put my personal data, my documents multimedia (video, music, photography ...). My / home partition of 9GB it does not duplicate the 2nd HDD? How to allocate you the different partitions on a 40GB HD? Can any one advice me for the same. Thanks in advance.
