Here it is!
The first step is to make some space in the system to install Ubuntu. So I booted Windows 7 and from the “computer management – disk management”, I managed to shrink the windows partition to 60 GB.
At the same time I started downloading the image provided by DELL on their website.: Canonical Ubuntu 10.10. Once the download completed, I created a USB Startup disk (System -> Administration -> Startup Disk creator).
Pressing F2 during bootup of the DELL Latitude 2120, I got into the BIOS. Here I changed the device bootup sequence to check for USB device before the HDD.
Rebooting with the USB startup disk in place, gives me a few option – including DELL recovery Linux OS partition only. I have selected this and it is now taking me through the Ubuntu install process, including creating new partitions…
The adventure has trully commenced!
