I want to install the 14.04 LTS version on my laptop where I use now 12.04 LTS, I want to use a Live CD and I don't know if it will erase my 12.04 or integrate it on grub in the start on my laptop.
1) Can I get the both on the same laptop using only the Live CD (Choosing in the grub interface)?
2) How can this be done?
Thank you.
