Dedicate more hard drive space to Ubuntu

I was running Windows 7 on my laptop but installed Ubuntu Linux as well. While installing Ubuntu I made an error and only dedicated 17 Gigs of hard drive space to Ubuntu and the rest to Windows. I would like to split my hard drive more evenly but cannot seem to figure out how to reconfigure Ubuntu to use more than the 17 Gigs. Any guidance would be greatly appreciated. Thanks!

Re-Partition your drive

You need to repartition your harddrive. Unfortunately you can't do this from inside either Windows or Ubuntu booted normally, since you can't repartition it while using it. You'll need to boot from a live CD that has partitioning software on it. Partition Magic is probably good choice:

Be sure to back up everything essential on both partitions beforehand, however, since partitioning is an inherently risky business.

Is there a simpler way to do

Is there a simpler way to do this that is less risky? Say for instance removing the Ubuntu platform from the computer leaving it with just Windows 7, then putting Ubuntu back on the computer? I guess I'm asking if it could be done similar to uninstalling a program, then installing it again. Thanks for your help!
