I have Ubuntu 10.10 install on my laptop. And I have a lot of data (nealy 40 GB) in the partition where Linux is installed. I cannot move this data to some where else.
If I now try to install Ubuntu 11.04 via USB (I am avoiding Upgrading via package manager because I have had some bad experiences with it), and not 'Format' my linux partition, are there any chances that my data in /home or /home/user1 or /home/user2 will vanish away?
