I want to install latest Ubuntu 12.04, once it gets released, on top of my actual 10.10. The main reason is that I get the "not supported" message, and cannot upgrade to newer distributions through update manager, because I could never solve some errors, so I want to do a fresh install
Please help me with some questions:
1) How should I do to reinstall 12.04 over my 10.10 without erasing /dev/sda3 contents, which stores all the backup info? (see image)
2) Are the partition sizes shown ok or should I increase/decrease any?
3) Is ok to format only /usr /var /tmp and /home? Should i format another to do a clean install?
4) What will happen with grub and other things when I install 12.04 over actual 10.10? Should I remove grub before launching installation?
Thanks a lot in advance,
