How to delete one Ubuntu if you have two installed

[kixdrummond]

I have Ubuntu 9.10 and Ubuntu Netbook Remix installed on my laptop, through a dual boot. How can I delete Ubuntu Netbook Remix with out deleting Ubuntu 9.10??

I have a Dell Latitude D610

You can format the relevant partition using Gparted or Palimpsest.

BUT do you know which Ubuntu is managing your Grub boot process? If it's UNR then you'll need to reconfigure Grub in 9.10.

I dont know what is managing it.

Are Gparted and Palimsest Ubuntu programs or terminal commands?

[audiomick]

Gparted is a partitioning tool that is standard in Ubuntu, I think. If it is not on the computer, you can install it from the repositories with synaptic package manager.
I am not familiar with the other program, but I assume it is something similar.

[mechro]

Gparted and Palimpsest are Ubuntu programs. In 9.04 Gparted is available from System > Administration > Partition Editor. I'm guessing that takes you to Palimpsest in 9.10.

I could tell you how to check the Grub stuff in 9.04, but since you're using 9.10 with Grub2 I'm a bit lost. I'll go and have a read about it but hopefully someone will come along and give you some advice.

OK, Palimpsest. Not much information there.

Can you open a Terminal (Applications > Accessories > Terminal) and enter the following command...


sudo fdisk -l

... that's a lower case L. It'll ask for your password.

Then enter the following command...


cat /etc/mtab

Post the results of these back here. You should be able to copy and paste the whole thing from the Terminal to your browser.

OK. So assuming you're doing all this in your 9.10 install it means dev/sda6 is your UNR installation. That's shown as 6.9 GB Unrecognized in Palimpsest.

You should be able to delete or reformat that partition in Palimpsest. I don't know the exact procedure because I haven't used Palimpsest.

Before you do that you'll need to check from which partition your grub bootloader is operating. I'll have a look at that tomorrow. Maybe someone else might chip in and help you.

Ok cool thanks.

[mechro]

Can you do two more Terminal commands so we can find out the Grub2 boot configuration...



cat /etc/fstab

and...


cat /boot/grub/grub.cfg

Post the results here.

Oh! Perhaps you're not using Grub2. It doesn't matter. Can you do...


ls /boot/grub

[kixdrummond]

christopher@andy-laptop:~$ ls /boot/grub
default fat_stage1_5 jfs_stage1_5 minix_stage1_5 stage2
device.map grubenv menu.lst reiserfs_stage1_5 xfs_stage1_5

christopher@andy-laptop:~$

[mechro]

That's fine. Now do...


cat /boot/grub/menu.lst

... that's a lower case letter L in lst

It doesn't really matter now, but how were you booting UNR? :? It's not listed in your boot menu.

Anyway, you can now delete partition sda6 shown as 6.9 GB Unrecognized in Palimpsest.

Also you have two swap partitions; Ubuntu is only using one of them. You can delete partition sda7 shown as 370 MB Swap Space in Palimpsest.

When you've deleted these partitions you will have some unallocated space on your hard drive. You can either save it for future use or, with a bit of partition manipulation, you could add the space to your Ubuntu installation on sda1. I could tell you how to do that using Gparted but I can't really help you if you want to do it with Palimpsest.
