我刚刚在联想 G50-70 上单启动了 Ubuntu 16.04 LTS。但现在它的启动速度比以前与 Windows 双启动时慢。它到达紫色空白页并挂起一段时间。
MCE日志如下:

答案1
也许它正在尝试挂载 Windows 分区但失败了。
如果是这种情况您应该将其配置为不要尝试安装 Windows 分区/etc/fstab
。
答案2
我只是猜测,但错误看起来像是芯片错误,可能是 CPU 或 RAM 中的错误。检查 RAM 是否正确插入可能是一个好的开始。内存缓存错误可能与 CPU 有关,因为某些 CPU 具有少量板载内存。线索是顶线 - 硬件错误 - 这不是软件错误,因此如果您可以访问计算机内部,请检查所有连接是否正常。在低级计算中,MC 可能指的是分配地址空间的内存控制器。我会彻底检查您插入的 RAM。
答案3
memtest86 ver 5.01 应该在您的启动菜单中 - 检查 RAM;刚刚经历了这一点 - 如果它不在您的启动菜单上;获取配置 grub 应用程序,然后添加 memtest。
