How To Un-Partition Something?

[cmd]

A little while ago I set up a 15GB or so partition for Ubuntu, which I won't be needing anymore thanks to the new Ubuntu installer (thanks PParks), so I'm wondering how to get those 15GB back. I'm not sure if I used the partitioner in the Ubuntu live disc or in Vista, hopefully I didn't need to remember. Thanks.

You need to wipe your hard drive to if you want just one big partition. But if you don't mind it being in 2 partitions then go to administrative tools on your control panel and then click on computer management. Then click on disk management. On the bar down at the bottom you will have a long dark blue area and a black one. On the black one, right click on it and click on create new simple volume. Then follow the wizard and let it format that partition.
