我剛剛安裝了Ubuntu。這是一條漫長而痛苦的道路，因為我犯了所有可能的錯誤。事情終於開始好轉了。當我打開電腦時，我會進入啟動選單。 Ubuntu 可以運行，但 Windows 不行。
如果我嘗試選擇窗口，它會進入黑屏，然後返回啟動選單。
我相信問題在於啟動菜單試圖打開窗口，dev/sda1但實際上窗口是在dev/sda2.這會導致黑屏發生大約五秒鐘，然後回到啟動選單！請幫忙！我很想保留 Ubuntu，但我需要存取 Windows。
這是我得到的完整啟動資訊日誌：

我最近也遇到了 GRUB 的問題。這是我的帖子：https://askubuntu.com/questions/119597/grub-rescue-error-unknown-filesystem/119661#119661。
啟動進入 Ubuntu。下載並運行啟動修復解決您的問題。選擇“推薦修復（修復最常見的問題）”選項。
實際上，您似乎擁有 Lilo，因此該解決方案可能不適合您。作為一種選擇，您可以用 GRUB 取代 Lilo，因為 GRUB 是最受歡迎的引導程式。
