I have a Win 7 and Ubuntu 11.10 multiboot system on my laptop. I am planning to upgrade Ubuntu, but I'd like to do it with a CD and make a new installation.
I am wondering if there is anything I need to know about before I start altering my system. I think I just have to format and choose the partition where my current Ubuntu OS is and set the boot for the entire HD and that way thing will go smoothly and after the installation the screen will appear again (the screen where I can choose between Win7 and Ubuntu). Is it so?
