安装Boot管理軟件 rEFInd

1. 下载地址：http://sourceforge.net/projects/refind/files/0.10.3/refind-bin-0.10.3.zip/download
2. 解压软件包；
3. 运行refind-install安装脚本；
4. 重启后你应该能够看到rEFInd启动菜单

rEFInd is a fork of the rEFIt boot manager. Like rEFIt, rEFInd can auto-detect your installed EFI boot loaders and it presents a pretty GUI menu of boot options. rEFInd goes beyond rEFIt in that rEFInd better handles systems with many boot loaders, gives better control over the boot loader search process, and provides the ability for users to define their own boot loader entries.
