centos 启动报 error can’t find command ‘:’解决方案

测试环境1台物理机太老了，又只跑了一个nginx服务，于是想把它迁移到虚拟化中，用“VMware vCenter Converter Standalone”6.4版，把它P2V到虚拟化中，启动时报以下错误。

需要按两次空格后，可以进入到启动界面，然后可以正常启动，其它方向无任何异常。

经分析，是因为vCenter Converter Standalone软件在作P2V迁移时，会错误在grub.cnf启动配置项文件中注释一些内容，我们把它修正，就正常了。

进入目标目录/boot/grub2，注意不是/root/grub2，也不是/boot/grub目录，备份现有的配置文件grub.cfg ，再编辑它。找到“removed by Converter”行，可以看到行首都有“：“号，在这些行首中，我们再加放“#”，注释掉这些内容，保存后，重启。

修改前状态

cd /boot/grub2/
cp grub.cfg grub.cfg.bak
more grub.cfg

修改启动项，并保存，然后重启服务器，进行测试，应该开机没有错误提示了。

vi grub.cfg
