grub的三种安装方式

1、install命令

install: install [--stage2=STAGE2_FILE] [--force-lba] STAGE1 [d] DEVICE STAGE2 [ADDR] [p] [CONFIG_FILE] [REAL_CONFIG_FILE] 

STAGE1：指定stage1文件所在绝对路径。 

DEVICE：指定vstage1装载的位置。 

STAGGE2：指定stage2文件所在绝对路径。 

ADDR：指定装载stage2的位置，如果不写，系统自动决定。

例如： 

boot为独立分区时：

grub> root (hd0,0) 

root (hd0,0) 

 Filesystem type is ext2fs, partition type 0x83 

grub> install /grub/stage1 (hd0) /grub/stage2 p /grub/grub.conf 

install /grub/stage1 (hd0) /grub/stage2 p /grub/grub.conf 

boot为非独立分区时：

grub>root (hd0,0) 

grub>install /boot/grub/stage1 (hd0) /boot/grub/stage2 p /boot/grub/grub.conf

grub> root (hd0,0) 

root (hd0,0) 

 Filesystem type is ext2fs, partition type 0x83 

grub> setup (hd0) 

setup (hd0) 

 Checking if "/boot/grub/stage1" exists... no 

 Checking if "/grub/stage1" exists... yes 

 Checking if "/grub/stage2" exists... yes 

 Checking if "/grub/e2fs_stage1_5" exists... yes 

 Running "embed /grub/e2fs_stage1_5 (hd0)"...  26 sectors are embedded. 

succeeded 

 Running "install /grub/stage1 (hd0) (hd0)1+26 p (hd0,0)/grub/stage2 /grub/grub.conf"... succeeded 

[root@client ~]# grub-install hd0  （或者是grub-install /dev/sda也行）

Installation finished. No error reported. 

This is the contents of the device map /boot/grub/device.map. 

Check if this is correct or not. If any of the lines is incorrect, 

fix it and re-run the script `grub-install‘.

 

# this device map was generated by anaconda 

(hd0)     /dev/sda
