10:10 I installed Ubuntu alongside Windows 7, after the installation was able to upgrade to version 4.11. Now I'm trying to update to version 11.10 but I get an error message saying it is not possible to upgrade, I decided to install a partition that I created the part, but when I start the PC directly opens Windows 7 does not appear to me the option to choose which want to start the operating system. I formatted the partition where you had installed ubuntu, I've been looking for tutorials where you learn how to install ubuntu on a partition part to try to understand what my problem. I wonder if I can explain how to install ubuntu on a partition that part so that when I connect the PC to show me the option to choose which system I want to start.
