This question already has an answer here:

I installed Windows 8 and then installed Ubuntu .The PC directly runs Ubuntu, it does not ask which system should it run.

Ubuntu is the latest version. It runs in too slow; if I open any application. It takes 3 to 5 minutes to open.

My PC configuration is 4GB RAM , 320GB HARD DISK.

Please help
