Merging two partitions

[Maxipower]

Hello,
I dont know if i posted this thread in the right section but ill just ask it here:

A few days ago i tried to use bootcamp to install windows, i had to divied my hardrive into 2 partitionts, one 150GB for MacOSX and one 50GB for Windows. Halfway throughout the process i realizes i lost my windows disc and therefore i couldnt proceed! Now i have a partition of 50GB which is unsued...

Now my questions is, is it possible to add these 50GB to my current 150GB again, in other words to merge them?!?

There are no files in my Bootcamp unsued partition! Now is this possible ??
Please help

Uses BC Assistant to merge the two partitions.

Here are the instructions:

Use the boot camp assistant to remove the partition, and regain the lost space.
