I have just changed my HDD on my pc to 500gb one. Since my motherboard has only one SATA port, i had to remove the older one. Therefore, i installed Windows XP on it first. Then, i rebooted and then booted from my USB containing Ubuntu 13.04. I selected install Ubuntu. I went through the first step (the neccessary requirements one) and then it took me to a step showing me 3 partitions. Actually, one of them referred to the whole HDD, whereas the other two were partitions. One of them was Windows XP NTFS partition. The pther was Windows recovery partition.

I don't know why, it did not show me the step to select "Install alongside Windows". It took me to a step where i had option to select to either wipe the whole hdd, or "Something Else".
I counted the steps, it was 1, 2 and then suddenly 4! Whats up with this thing? Corrupted pen drive?

Although i can do one thing, which i think should work. I can use some partition tool on windows to create another partition, and then select that partition for ubuntu. But before doing that i want to know whether this problem can be solved without it or not. Because i know that GParted is a powerful tool, and that would be a better option.
