Newbe... removal & partition resizing

[Duke of E]

No longer leading edge, so call me a "newbe". Ok, I've just installed Ubuntu 9.04 (64 bit) onto my dual boot of Windows Xp & Ubuntu 8.10. I now seem to have a three way boot and 9.04 warns that I don't have enough space to update files. I suspect that the partition is too small. So how do I remove one or both Ubuntu programs and/or how do I resize the partitions? I have a HP Pavillion a1610n and have been warned that some HP units have issues with GParted live. My HDD shows a total of 191GB with 31.9 GB free (NTSF). Can someone please help this out of date dude?

System info : HP Pavillion a1610n / AMD 64 / 2.2 gig / 3.43 GB Ram
Windows XP pro / ver 5.1.2600 SP3
Nvidia driver ver 173.14.12
OS Linux _86_64
Present Options - Windows Media Edition
Ubuntu 8.10
Ubuntu 9.04

Thanks in advance!

I'd try GParted, but I don't know if your hardware has problems with it.
