如何用UEFI启动Win8光盘，把Win8操作系统安装到GPT分区形式的硬盘上
推荐回答（5个）
虽然我暂时用普通BIOS模式装的win8，但我准备下次换硬盘用UEFI装，听说快好多。。
我的是10年末的老笔记本了，主板竟然支持UEFI，这个是Intel自带的UEFI BIOS界面，应该和你那个界面一样。。然后进BIOS的界面，里面某一栏会看到 UEFI的选项，后面是enabled就对了；然后在启动顺序那栏吧uefi-dvd放在最前面；我记得就在这一栏的最下面应该有个从uefi介质启动之类的选项，你可以试一试，我估计这个就是专门用来uefi启动的。。
哥们是要装双系统吗？开始我也碰到这种情况~~反复分区装都不行~~。最后总结出2个办法~一个是分区格式直接不用改,直接用MBR格式~开机装系统是按F8出快速启动菜单~选不带UEFI开头的光驱启动~~这样WIN8直接可以装~装完后再把WIN7激活一下就行了~~另一种方法用Diskgen软件把硬盘转化为GPT格式.然后从新分区~~~分完前面有2个隐藏分区啊~~汗。。然后装的时候选带UEFI开头的光驱装。。。但这种方法有个弊端就是装完双系统后WIN7不好激活啊~试了好多软件都不行~~建议楼主在多试几次~~我倒腾这个倒腾了2天。。不愿折腾了~最后还是MBR装的~win7和win8都支持MBR和GPT格式磁盘分区的。无非GPT支持2T以上的大硬盘~~现阶段几乎无用啊~~~你提示那个错误就是磁盘分区格式为MBR~但开机选的UEFI启动自动默认为GPT格式的~~~这样是装不了了~~~希望能帮到楼主~呵呵~
直接点升级了，win8普通机子都可以完美运行的。感觉比win7还好。安装双系统，浪费硬盘了。 直接在你的可以进入的系统里面，把你的光盘里面的文件复制到文件夹，从文件夹里面直接安装。那么麻烦干嘛。
你这个win8是32位的还是64位的？还有你看看光盘目录下有没有EFI/boot/bootx64.efi或者EFI/boot/bootx32.efi?如果没有的话，那就是光盘的问题。我记得32位的win8没有EFI启动的功能,也就是在光盘目录下没有EFI/boot/bootx32.efi这个文件，所以不支持UEFI启动。而通过你的描述，判断主板上的BIOS是支持UEFI的，并且没有问题。所以我猜测你的安装盘是32位的，才引起这个问题。
UEFI安装要满足下列条件：
1、主板支持UEFI。
2、安装操作系统的硬盘分区表格式应为GPT。
3、安装程序启动时，引导安装光盘的选项应当为UEFI。
如果上述三个步骤都满足而且安装过程正确还是无法启动的话，就应当检查是否硬盘的兼容性出现问题。例如SATA接口的兼容性或者是硬件中是不是有不支持UEFI接口的硬件。
