I very much enjoy using Ubuntu, Linux. However I have mucked up by PC software. I had Windows XP ser 3. But try to install Linus 13.10 (I Think). However found the PC did not have enough space to support both Linux and windows. So when I loaded Ubuntu onto the PC from the DVD Linux disc....found it just got a certain way and stopped........
HELP I need to remove both that is on the hard drive. Windows for good, reinstalling Ubuntu Linux .

However I would you good people if you can help me to give me as much info on slow step by steps.

I thank you all, hope you can help me.

If you are serious about deleting everything from your disc and installing Ubuntu (and have backed up all your data) it should be pretty straight forward.
The Ubuntu installer should at some point give you the option to replace the existing installation and install Ubuntu as standalone system.
From your question it sounds like so far you only booted Ubuntu into a live system so probably nothing needs to be removed.

If you want more detailed help please ask more detailed questions. I.e. run the installer and tell us where you are stuck / where you are uncertain which way to go. If applicable post exact error messages and / or screenshots.

On a side note you may want to wait for Ubuntu 14.04 to come out (due this month) which will be an LTS (long term support) release. This means it gets security updates for a much longer period of time than a standard release.

I assume that you have ALL of your data backed up. I also assume that you have no other drives attached (external HDD, flash drive, SD card, etc).

Boot from the Ubuntu DVD, and select "Try without installing"
When everything loads, open a terminal and type:
If it was a Windows install, you should see 2 partitions: one for the Windows bootloader, and one for Windows itself. Delete both of these.
Now start the installation process. There should be an installer icon on the desktop.
When you get to the part where you choose between "Install Ubuntu xx.xx" or "Something Else," choose "Something else." When the partitioning menu appears, make a swap partition first, and put it at the end of the free space. I've heard all kinds of ranges for what size the swap should be, but twice your RAM seems to be a common suggestion (but see below for my personal opinion). Once you do that, make an ext4 partition. (If you have an SSD, choose ext2.) Make sure that the mount point is "/"
Now you can continue the installation like normal.

About the swap size: I hear "twice your RAM" a lot, but don't completely understand it. For example, say you have 256 MB of RAM. To me, it sounds like you'd want more than 512 MB of swap, but then again I don't know that much about how everything fits together.

Had a good read and thanks to you good people for helping. Will be trying it out over the next few days.
