Windows10安装DockerToolbox出现Hyper-V问题，无法使用

一、问题描述：安装过Docker Toolbox，卸载后，重新安装，无法正常使用，提示

Running pre-create checks...
Error with pre-create check: "Hyper-V is installed. VirtualBox won't boot a 64bits VM when Hyper-V is activated. If it's installed but deactivated, you can use --virtualbox-no-vtx-check to try anyways"
Looks like something went wrong in step ´Checking if machine default exists´

二、解决方法:

1.以管理员方式打开cmd,输入以下命令。（注意：其中第二行命令参考第一行命令返回的结果）

C:\>  bcdedit /copy {current} /d "No Hyper-V" 
The entry was successfully copied to {ff-23-113-824e-5c5144ea}. 

C:\>  bcdedit /set {ff-23-113-824e-5c5144ea} hypervisorlaunchtype off 
The operation completed successfully.

2.重启电脑，

3.下载安装Docker Toolbox。

4.打开安装目录，找到start.sh。

编辑start.sh，找到下面的代码片段：
 

STEP="Checking if machine $VM exists"
if [ $VMEXISTSCODE -eq 1 ]; then
  "${DOCKERMACHINE}" rm -f "${VM}" &> /dev/null || :
  rm -rf ~/.docker/machine/machines/"${VM}"
  #set proxy variables if they exists
  if [ -n ${HTTPPROXY+x} ]; then
    PROXYENV="$PROXYENV --engine-env HTTPPROXY=$HTTPPROXY"
  fi
  if [ -n ${HTTPSPROXY+x} ]; then
    PROXYENV="$PROXYENV --engine-env HTTPSPROXY=$HTTPSPROXY"
  fi
  if [ -n ${NOPROXY+x} ]; then
    PROXYENV="$PROXYENV --engine-env NOPROXY=$NOPROXY"
  fi

  "${DOCKERMACHINE}" create -d virtualbox $PROXYENV "${VM}"
fi

将最后第二行改为：

"${DOCKERMACHINE}" create -d virtualbox --virtualbox-no-vtx-check $PROXYENV "${VM}"

5.可以正常使用Docker Quickstart Termial了。
