linux如何efi安装win7,在EFI+GPT硬盘上利用grub2实现Linux/Win7/win8等多重启动

接上文啊&＃xff0c;本人电脑&＃xff0c;Lenovo Y410P的笔记本&＃xff0c;主板UEFI&＃43;GPT硬盘&＃xff0c;预装的Windows 8&＃xff0c;至于如何安装Linux&＃xff0c;请参见空间其他文章&＃xff0c;里面的说明比较细致&＃xff01;&＃xff01;&＃xff01;

本文就来说明一下&＃xff0c;怎么用Linux的grub2来引导Windows 8&＃xff1b;

当你按照前文的方法安装后&＃xff0c;只能通过开机按F12来选择系统了&＃xff0c;若不选择的话&＃xff0c;会默认进入EFI引导的第一个系统&＃xff1b;如果你一点没有调整的话&＃xff0c;那么他会默认进入Linux的&＃xff0c;你也可以在主板设置里调整启动顺序&＃xff0c;让Windows 8变成第一个&＃xff0c;但是&＃xff0c;在按照本文操作之前&＃xff0c;请将Linux的EFI启动项“Red Hat Linux”设置为第一启动项&＃xff0c;至于为什么&＃xff1f;自己想吧&＃xff01;

在安装完Linux后&＃xff0c;grub引导中是存在的准备引导Windows的others的选项的&＃xff0c;但是一使用就出错&＃xff0c;本文就是将他修改正确&＃xff1b;

附加我的硬盘分区图&＃xff1a;

由上图可知&＃xff1a;序号2的分区&＃xff0c;即260M的FAT32分区&＃xff0c;是系统的EFI分区&＃xff0c;在linux中显示为sda2&＃xff0c;即hd(0,1)&＃xff1b;

原来的grub.conf文件(位置在/boot/efi/EFI/redhat/目录下&＃xff0c;想要看到&＃xff0c;必用root&＃xff0c;sudo不好使)内容如下&＃xff1a;

# grub.conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE: You have a /boot partition. This means that

# all kernel and initrd paths are relative to /boot/, eg.

# root (hd0,9)

# kernel /vmlinuz-version ro root&＃61;/dev/sda11

# initrd /initrd-[generic-]version.img

#boot&＃61;/dev/sda2

device (hd0) HD(2,1f4800,82000,f5ca45c0-7ee8-4b19-b521-5404b3964deb)

default&＃61;0

timeout&＃61;0

splashimage&＃61;(hd0,9)/grub/splash.xpm.gz

hiddenmenu

title CentOS (2.6.32-431.el6.x86_64)

root (hd0,9)

kernel /vmlinuz-2.6.32-431.el6.x86_64 ro root&＃61;UUID&＃61;87a7c08d-411b-4b4c-b35f-8fb72b7c1776 rd_NO_LUKS rd_NO_LVM LANG&＃61;en_US.UTF-8 rd_NO_MD SYSFONT&＃61;latarcyrheb-sun16 KEYBOARDTYPE&＃61;pc KEYTABLE&＃61;us rd_NO_DM rhgb quiet

initrd /initramfs-2.6.32-431.el6.x86_64.img

title Other

rootnoverify (hd0,4)

chainloader &＃43;1

现在进行修改&＃xff0c;主要是修改了上面的最后三行的内容&＃xff0c;最后三行改成如下&＃xff1a;

title Windows 8 (Simple Chinese X64)

menuentry "Windows 8 (loader)"

root (hd0,1) #这里的(hd0,1) 是上面的/dev/sda2转化来的&＃xff0c;sda2对应(hd0,1) &＃xff0c;sd1对应(hd0,0) 等等&＃xff01;

chainloader (hd0,1)/EFI/Boot/bootx64.efi #这里的(hd0,1)的意义同上&＃xff01;

最后的grub.conf文件内容&＃xff0c;也就是改成如下样子&＃xff1a;

# grub.conf generated by anaconda

#

# Note that you do not have to rerun grub after making changes to this file

# NOTICE: You have a /boot partition. This means that

# all kernel and initrd paths are relative to /boot/, eg.

# root (hd0,9)

# kernel /vmlinuz-version ro root&＃61;/dev/sda11

# initrd /initrd-[generic-]version.img

#boot&＃61;/dev/sda2
