ubuntu9.10(karmic)修复Windows系统引导

阅读更多

ubuntu9.10使用了grub2(不确定是不是2)，与以往不同新版本的grub 的引导配置文件不再是menu.lst而是/boot/grub /grub .cfg ，这个文件默认是只读的，因此在修改之前需要先将其改为可写。

root@ptubuntu:/home/ptubuntu# chmod +w /boot/grub /grub .cfg

然后就可以修改了。给其中加上如下内容即可

root@ptubuntu:/home/ptubuntu# vi /boot/grub /grub .cfg

添加后内容如下：

### BEGIN /etc/grub .d/00_header ###
set default=0
set timeout=5
set root=(hd0,7)
search –no-floppy –fs-uuid –set 5deb40f9-217d-408d-bc7c-be463cbfea7b
if loadfont /usr/share/grub /ascii.pf2 ; then
set gfxmode=640×480
insmod gfxterm
insmod vbe
if terminal_output gfxterm ; then true ; else
# For backward compatibility with versions of terminal.mod that don’t
# understand terminal_output
terminal gfxterm
fi
fi
### END /etc/grub .d/00_header ###

### BEGIN /etc/grub .d/05_debian_theme ###
set menu_color_normal=cyan/blue
set menu_color_highlight=white/blue
### END /etc/grub .d/05_debian_theme ###

menuentry “Microsoft Windows XP Professional” {
set root=(hd0,1)
search –no-floppy –fs-uuid –set 4a807ca0807c93e3
drivemap -s (hd0) $root
chainloader +1
}

上面这段黄色就是原来自带的。现在要改为下面红色。

menuentry “Microsoft Windows XP Professional” {
set root=(hd0,1)
chainloader +1
}
### BEGIN /etc/grub .d/10_linux ###
menuentry “Ubuntu , Linux 2.6.31-3-generic” {set root=(hd0,7)
search –no-floppy –fs-uuid –set 5deb40f9-217d-408d-bc7c-be463cbfea7b
linux   /boot/vmlinuz-2.6.31-3-generic root=UUID=5deb40f9-217d-408d-bc7c-be463cbfea7b ro   quiet splash
initrd  /boot/initrd.img-2.6.31-3-generic
}
menuentry “Ubuntu , Linux 2.6.31-3-generic (recovery mode)” {
set root=(hd0,7)
search –no-floppy –fs-uuid –set 5deb40f9-217d-408d-bc7c-be463cbfea7b

}
### END /etc/grub .d/10_linux ###

### BEGIN /etc/grub .d/20_memtest86+ ###
menuentry “Memory test (memtest86+)” {
linux   /boot/memtest86+.bin
}
menuentry “Memory test (memtest86+, serial console 115200)” {
linux   /boot/memtest86+.bin console=ttyS0,115200n8
}
### END /etc/grub .d/20_memtest86+ ###
