Dual booting two Ubuntu versions

I want to install two Ubuntu versions on the same system (like dual boot). I'm using Ubuntu 9.10 and I also want to install Ubuntu 10. Please tell me how I might do this, as I don't know enough about Linux.


Simply use the Ubuntu 10.10 CD/USB installer and, when prompted, choose to install side by side with the existing operating system. The process is the same as installing Ubuntu side by side with Windows.

Please read the full installation instructions here. Click 'Show me how' on step 4 of the instructions.


It would be be like dualbooting with windows.Install ubuntu 10 on a seperate partition,and make sure you are using the grub boot loader from ubuntu 10..
