Re-installation problem

1. Backup your personal documents, music, pictures et cetera, on an external storage medium. Like a CD, a DVD, an external hard drive or a USB memory stick.

2. Boot your computer from the Ubuntu Desktop CD and start GParted:
Click on the grey Ubuntu logo in the top of the side panel (Dash home). Query: Gparted.
Click on Gparted Partition Editor.

Then use this fine disk partitioner, to completely destroy the Ubuntu partitions. All actions you do in Gparted have to be confirmed by a click on the Apply button in the panel (the green tick V), before they are being executed

don't format the Ubuntu partitions, just destroy them. Including the swap partion! The result will be "unallocated free space".

Note: the swap partition needs to be unmounted before you begin. In Gparted, do as follows: click with the mouse on the swap partition, then right click with the mouse, and choose Swapoff. Then you can proceed. Destroy the swap as well!
and Reboot your computer. Don't remove the Ubuntu CD.

The whole problem in itself is I can not BOOT from the CD.

I just went into set-up of my computer and manually change the BOOT ORDER .....still no change,it simply goes back to the already installed OS.Is there anyway to install from the contents of the disk itself or perhaps from the terminal?

have you followed instruction provided my me ? it should work.
please try and let us know

then must be problem in your media ... try burning new ubuntu

Perform MD5 test the ISO you downloaded
use unetbootin to put the data on the USB stick

try booting now hope it will work

thanks

Made new CD ...did MD5 test....still no change.Is there no way to install from the command line or perhaps within the flies/folders of the CD itself?

Thanks

Thanks praerit, that solved my question.
