Uninstalling a dual boot

[Alecmag]

I am currently dual booting Jolicloud and Ubunut netbook remix, and I decided I like Ubuntu better. I'd like to remove Jolicloud from my system, but I don't know how.

I appreciate any help you can offer.

It could be done several ways. You could just delete the Jolicloud partition and remove the grub entry yourself or you could just install another distro over it, thereby erasing everything on that partition. Post the output of this command so we can see what your disk structure looks like.

sudo fdisk -l

Which partition is Ubuntu and which is Jolicloud?

Post the output of df -h command too.

sudo fdisk -l
df -h

sudo fdisk -l gives me:

df -h

I'm not sure which partition is which. I installed jolicloud first over the whole system and the ubuntu after that if it helps.

You issued the above commands while booted into Ubuntu, is that correct?
So from the output, I think it's safe to assume /dev/sda6 is Ubuntu. Now you can just boot into Ubuntu and issue this command.
sudo fdisk /dev/sda6
Press "m" at any time for help.
Press "d" to delete the partition..I think it will ask you which one, to be sure. Then when you are done, press "w" to write the partition table and exit. If you goof up at any time, just exit without saving and everything will be back the way it was, but once you press "w" it's a done deal.
You should also delete the extra /swap partition too. Probably /dev/sda7
Then you'll need to edit your Ubuntu grub configuration.
I believe Ubuntu netbook remix uses grub2, so you need to edit /boot/grub/grub.cfg and delete the entry for jolicloud.

I think Ubuntu fresh install is a best way to go now.
/dev/sda1 is a Primary Partition and if you delete it, it will be a bit complicated to merge free space into /dev/sda6, Logical Partition where you have installed Ubuntu.

You have two swap partitions and first one is of Jolicloud. If you delete it, you have to edit a few conf files. Otherwise, Ubuntu won't boot up because partition deleting will change device names assigned to all partitions.

It's possible to fix everything without fresh installation but you have to recreate partition table and edit a few conf files.

Is there a way to do a reinstall other than doing a live USB?

I can do that too, just wondering if there's an easier way once ubuntu is already installed.

[devils casper]

There aren't much choices. Easiest way is, install Ubuntu using external CD/DVD drive.
