I have an old desktop with ubuntu 10.04 running on it. It's installed through wubi on a windows drive.

What I want to do is -

1)Install the latest 12.04 LTS on my desktop.

2)Completely remove windows from my system (all partitions including the one from which ubuntu currently runs) i.e. completely erase all data from the current disk.

Issues I'm encountering while trying to achieve the above -

1)No internal cd/dvd drive , although I do have an asus external dvd writer that could be plugged in through a usb port. However, I'm not sure if the old desktop would allow booting through an externally plugged in usb dvd writer (firmware might not support this) in case I do try this using a ubuntu bootable disk.

2)Similarly, the old firmware might not allow booting from a usb pen/flash drive in case of a bootable ubuntu usb drive.

I'm not sure if the motherboard firmware could be upgraded and perhaps I probably want to avoid this to prevent corrupting firmware and spending time on this.

So, what I want to know is

1) What are my options/tools to completely erase everything from the disk ?

2)How to install Ubuntu 12.04 LTS Desktop version on the hard drive given the above constraints ?

Edit - Just for your information , the motherboard is Asrock conroe945g - dvi.

Please, edit your answer and add your computer model so we are able to verify if it can boot from USB. –  edwin Jun 30 '13 at 23:09
If you have internet access, you can try the Net Install. Download the network installer for 12.04 LTS. –  Mitch Jul 1 '13 at 6:35
@edwin - it's a custom made pc, the motherboard is Asrock conroe945g - dvi... –  user481913 Jul 1 '13 at 11:15
Your mainboard should boot from bootable USB drives. If it really does not and if you have a second computer around, check out PXE booting (your mainboard supports it). Mitch linked to the netinstall image above, the corresponding manual is here: help.ubuntu.com/12.04/installation-guide/amd64/… and there are numerous tutorials on the Web. Also, the same process is well documented in the Debian manual - details differ for Ubuntu of course. –  soulsource Jul 1 '13 at 12:38
You can of course always put Ubuntu on a usb drive, and see if it boots the Live CD environment. You don't need to install anything just yet to try that out. –  Gx1sptDTDa Jul 1 '13 at 13:22
