I'm posting this question because I have the intention to update my Windows 7 (damaged installation) to Windows 8 but I don't know if this process may affect my Ubuntu 12.04 install. I have 220 GB dedicated to Windows, 65 GB to Ubuntu, a 10 GB Recovery and 1.5 GB swap partition.
And one final doubt: Is it recommended to update Ubuntu to 12.10? If the answer is yes, how can I guarantee a safety update?
