rEFIt菜单没有标识os

Question

我试图为我的mac(OSX，Ubuntu14.04，Windows8.1)设置一个三引导系统，但是rEFIt无法识别Ubuntu，而是显示未知的os图标。它还显示了Ubuntu和Windows的多个图标。这是分区检查人员说的

Answer 1

rEFIt不再被开发。尝试安装我的rEFInd；它基于rEFIt，但正在积极开发。在OS中安装它，或者使用--alldrivers选项install.sh，或者手动安装用于Ubuntu的任何文件系统的EFI文件系统驱动程序(默认情况下是ext4fs)。(手动安装文件系统驱动程序涉及复制一个文件；有关详细信息，请参阅司机文件。)如果一切顺利，您应该能够从rEFInd启动Ubuntu，尽管最终可能会有额外的启动选项，您想要从菜单中删除。

窗户是另一回事。如果它能像现在一样启动，我会很震惊的。要使其启动，您需要用传统的保护MBR替换混合MBR，并对Windows进行EFI模式安装，或者编辑混合MBR，使其包括您的Windows分区(#5)。第一种是更清洁的解决方案，但不能保证有效。第二个解决方案比较传统(在Mac上)，但它延续了混合MBR的使用，这是一个丑陋和危险的黑客。
