Ubuntu partitioning

How do I create another partition for Ubantu without destroying my Windows one?

i would like to know as i want to install it without destroying anything

As the Ubuntu installation notes say in plain English, the installer will resize your existing partitions to make room for Ubuntu.

it says not enough space, oh well, guess i gotta get another hard drive...

well i tried Ubuntu, the partitioning thing in there is dodgy as anything. I already made some raw data using Partition Magic, then it took me like 30mins to work it out, but not only that, ubuntu wouldnt read off my cd/dvd combo drive so i had to get an old one. After working out how to install it, the ubuntu installer froze at about 10% into the installation and then when i rebooted my windows partition was stuffed and would not boot, i had to restore and lost all the data on my C:\ partition.

just make sure you know what your doing first.
