<p class="p"><span style="font-family: 宋体">这就是一个问题。</span></p>
<p class="p"><span style="font-family: 宋体">问题的原因就是：不能根据上面启动的路径找到</span>U<span style="font-family: 宋体">盘，也就找不到要加载的</span><span style="font-family: Verdana">CentOS</span><span style="font-family: 宋体">镜像。也就是不能找到正确的</span><span style="font-family: Verdana">U</span><span style="font-family: 宋体">盘的位置</span></p>
<p class="p"><span style="font-family: 宋体">解决方法：</span></p>
<p class="p"><span style="font-family: 宋体"> 重启，到上面这一步，然后看到上面的提示：</span></p>
<p class="p"><span style="font-family: 宋体"><img src="https://img2018.cnblogs.com/blog/1331300/201906/1331300-20190626172212117-540059904.png" alt=""></span></p>

<p class="p"><span style="font-family: 宋体">把上面这个，修改为下面这个，功能是</span> <span style="font-family: 宋体">用来查出来</span> CentOS<span style="font-family: 宋体">系统镜像文件写在的</span><span style="font-family: Verdana">U</span><span style="font-family: 宋体">盘到底是</span><span style="font-family: Verdana">sda</span><span style="font-family: 宋体">还是</span><span style="font-family: Verdana">sdb</span><span style="font-family: 宋体">还是</span><span style="font-family: Verdana">sdc</span></p>

<p class="p"><span style="font-family: 宋体">可以准确的找到这个</span>CentOS<span style="font-family: 宋体">镜像文件是存在于</span><span style="font-family: Verdana">sdc4</span><span style="font-family: 宋体">的。</span></p>
<p class="p"><span style="font-family: 宋体">然后重启电脑，</span></p>
