I have no idea if I have /home on a separate partition - how do I check? (sorry if this question makes me sound like a moron. I really am rather inexperienced with Ubuntu)

If you don't know, then you probably don't have it on a separate partition. To check, open a terminal and type in "mount | grep home" and copy and paste the output here. It should have a line like this

/dev/mapper/vg_ssd_00-home on /home type ext4 (rw)

and maybe another one if you encrypted the home folder.

Hi

This is what I got - does that make any sense?

gvfs-fuse-daemon on /home/username/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=username)

Kind of, it means if you only got this line then you don't have a separate home partition. So before you delete the old partition, you should backup all your documents or the whole folder /home/username to be safe. To see all "hidden" files and folders starting with a dot you need to press CTRL+H while in your home folder.

Then delete the old partition (double or even triple check before) and resize the new partition.

Thanks - I guess I need to create a home partition after I've sorted this out. I got gparted and opened it up - problem is, I'm not sure which partition is which OS. The ntfs one is Windows XP (I presume) but the others are a mystery. Do you know how I can work out which is which?

Please boot into the new Ubuntu (the one you want to keep) and post the output of

sudo fdisk -l

and

mount

Here you go:

Sorry, have to leave to watch the match now. Back later or tomorrow...

Ok, here we go. Before we start, double check if you really booted the Ubuntu you want to keep when you got this output. It shows that /dev/sda5 is mounted on your root directory. So sda5 we want to keep and sda6 (the corresponding swap partition). Did you make a backup of your home folder (including hidden files) to an external drive?

Before you start, can you boot the new Ubuntu again and post the content of /etc/fstab/?

cat /etc/fstab

Crispy_Ambulance

Here you go:

everyone@everyone-desktop:~$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name

Might not be around tonight to proceed much further, but should be able to carry on tomorrow. Thanks for your time, btw, much appreciated.

Ok, let's start. Boot your PC with the LiveCD and start the Partition Editor (gparted). Do not touch sda1 as this is your Windows. Delete sda7 and sda8 (both are physically between sda1 and sda5) and resize sda5 to the maximum available space.

DO NOT RESTART YET! (Edit: Actually you could restart and see if everything works already. If not, boot from the LiveCD again and proceed with the things below)

Post here again the output of

sudo fdisk -l

and

sudo blkid

It might be possible that the device names and/or the corresponding UUID's have changed and you would not be able to boot your Ubuntu. In this case we have to amend your /etc/fstab before rebooting. But don't be too worried, everything can be fixed with the rescue mode of the LiveCD unless you delete the wrong partition of course. But even in this case we could just reinstall Ubuntu since you have a backup of your files.
