Актуализирането на ядрото в Ubuntu 12.04 LTS изглежда не работи

Опитвам се да актуализирам ядрото си за Ubuntu 12.04 LTS от 3.4.0 до най-новата налична версия, но uname -r продължава да връща 3.4.0 без значение какво правя. Също така се опитах да рестартирам системата си няколко пъти, без резултат.

Резултатът от sudo update-grub е както следва:

Би било чудесно, ако някой знае как да актуализира/надстрои до най-новото ядро. [Когато казвам актуализация, не съм напълно сигурен какво включва това, но се опитвам да инсталирам заглавките, изображението и особено да изградя модулите (защото вярвам, че VirtualBox няма да работи на моята система поради някакъв проблем с модула)].

Предупреждение, направих много търсения в Google, за да се опитам да намеря отговора, така че опитите ми да разреша този проблем са изключително разнообразни, но моите работни познания за цялата идея на ядрата (и актуализирането им) и какво се състои от тях, е доста ограничен.

Ще се радвам да изпълня всякакви команди в терминала, ако е необходимо, и ако попаднете на отговор, моля, имайте предвид, че аз съм нещо като „новак“ в ядрото, толкова подробно обяснение и стъпки, или връзка(и) ) за това са изключително оценени.

Като последна бележка, използвам 32-битов ChrUbuntu, инсталиран от скрипта на Джей Лий (само за информация, неизвестните Linux дистрибуции на /dev/sda3 и /dev/sda5 са ChromeOS [ОС по подразбиране за моя chromebook]), което може или може да няма нищо общо с този проблем, но аз не съм експерт, така че всяко прозрение би било готино, но в никакъв случай не е необходимо.
