Ubuntu Linux, Windows XP 双系统重装Grub2
时间:2011-05-27 来源:阳光真强烈
一般安装Linux, Windows双系统都是先安装Windows然后安装Linux,这种情况下Grub会自动检测到Windows并添加到启动列表中。如果安装顺序颠倒则可以有以下解决方法:
- 安装Grub4Dos
- 使用Ubuntu LiveCD安装Grub到MBR
新版的Ubuntu使用的是Grub2,命令与Grub稍微有一些不同,大致操作如下
my-desktop:~$ sudo grub-setup -d /media/disk/boot/grub /dev/sda
其中disk和sda需要根据Linux所在硬盘进行调整。
以下是grub-setup的帮助信息
my-desktop:~$ sudo grub-setup --help
Usage: grub-setup [OPTION]... DEVICE
Set up images to boot from DEVICE.
DEVICE must be a GRUB device (e.g. `(hd0,1)').
-b, --boot-image=FILE use FILE as the boot image [default=boot.img]
-c, --core-image=FILE use FILE as the core image [default=core.img]
-d, --directory=DIR use GRUB files in the directory DIR [default=/boot/grub]
-m, --device-map=FILE use FILE as the device map [default=/boot/grub/device.map]
-r, --root-device=DEV use DEV as the root device [default=guessed]
-f, --force install even if problems are detected
-s, --skip-fs-probe do not probe for filesystems in DEVICE
-h, --help display this message and exit
-V, --version print version information and exit
-v, --verbose print verbose messages
