Last night I installed Lubuntu 11.10 on my desktop PC. Before that I only had Ubuntu 11.10, but now I have a "Dual-Boot" PC, with GRUB. Now, I want to uninstall Lubuntu because it doesn't like to me.
I tried to do that on Lubuntu's Live-CD GParted, but it has partitions that I don't know. And I don't want to play with that, I don't want to lose my Ubuntu data, these are my partitions:

The 38 GB partition is Ubuntu.
What I need to do is delete Lubuntu and enter to Ubuntu directly on the boot. Also, remember the Swap's partition!

sudo apt-get install lubuntu-desktop, Instead of creating partions at Random. sda6 and I guess sda7 are Lubuntu's partitions, delete those. – Uri Herrera Feb 14 '12 at 22:58
