How do I give more disk space to Ubuntu?

[seananigrins]

Hello,
I am new to Ubuntu. Just installed today. I have windows vista and Ubuntu so a dual boot system.
When I installed Ubuntu the largest amount of space it allowed me to give the operating system was 30gb (i think?) I would like to give Ubuntu more of the hard disk space as I have plenty and would like to install more apps. etc. in Ubuntu. How do I give more space to Ubuntu then? My hard drive is 200gb and windows vista is using 39gb and ubuntu 30gb. I want to give ubuntu at least half of the drive. Any help would be appreciated. thanks much.

Before providing details, let's get a look at your partitions. Open a terminal, enter "sudo fdisk -lu" (that's a lowercase L, not a one) and post the results back here.

Thanks for the reply Mark.
Actually, I redid the installation and just used the whole drive (erasing vista).
Hopefully I will be able to use this Ubuntu.
Thanks though for offering your help.
