Ubuntu 是一款開放原始碼的免費作業系統，號稱開機速度快，音訊、上網能力強大。它是 Linux 作業系統，採圖形介面，雖然仍處於小眾市場，但國內外皆有死忠追隨者，並自發成立社群，估計台灣就有 5 至 10 萬以上的使用者。由於使用者數目增加，加上 Linux 系統的電源管理能力普遍受肯定，已開始有電腦大廠計劃推出預裝 Ubuntu 作業系統的桌機、筆電和小筆電。
這款作業系統的安裝比 Windows 還要簡易，整個安裝過程還不到半小時。下載回來的檔案為 ISO 檔，可以用燒錄軟體轉為安裝光碟，如果安裝於虛擬系統工具上則無需理會。安裝時，只要將光碟放入光碟機，重新開機 (須先設定為光碟開機)，然後按照螢幕上的指示一步一步進行即可完成安裝過程，第一步通常是選擇語言，然後就是設定時區，再來就是設定鍵盤按鍵配置，選用建議選項｢USA｣即可，其餘再按照螢幕上的指示進行。
