我刚买了一台装有 Windows 8 的新戴尔笔记本电脑，并尝试安装 Ubuntu 14.10。我使用了启动盘创建器，PC Intel x86 桌面图像创建可启动的 FAT32 格式的 Ubuntu USB 驱动器。我检查了 .iso 文件的 md5sum，发现它与官方 md5sum 匹配。我从它启动了新 PC，它显示了以下输出行。

等待 5-10 分钟后，我手动重启并重新创建了 USB 驱动器。我重新启动后结果相同（停在同一个地方）。
我认为第七行的错误（内核 BUG）是问题的根本原因，但我可能错了。有没有什么方法可以修复或绕过这个错误以成功安装 Ubuntu？
我尝试使用传统启动和安全启动，并开启和关闭 UEFI。同一根记忆棒在其他计算机上运行良好。
如果我可能遗漏了更多相关信息，请告诉我。
答案1
成功！我发现我需要禁用 Windows 上的快速启动才能成功安装 Ubuntu。
禁用快速启动的步骤：
- 转到“开始屏幕”并搜索“更改电源按钮的功能”
- 点击“更改当前可用的设置”
- 向下滚动并取消选中“打开快速启动”。
修复这个问题后，我确实遇到了Ubuntu 14.04 LTS 实时 USB 启动错误（gfxboot.c32：不是有效的 COM32R 映像），有一个简单的解决方法。
