grub一例
功能： 多重引导，引导多个操作系统
主引导 lilo(redhat)
lilo(Redhat)——〉NTOSLOADER(win2k) + REDHATLINUX + GRUB(redhat) + LILO(cosix)
WIN2K+LILO(redhat)+LILO(cosix) + grub(redhat)
NTOSLOADER(win2k) + LILO(redhat) + COSIXLINUX
REDHATLINUX + COSIXLINUX + NTOSLOADER(win2k) + LILO(COSIX)
注意LILO安装在了/dev/hda 和 /dev/hda3
1.分区、系统、和引导
分区 系统 引导
/dev/hda Lilo(Redhat)
/dev/hda1 win2 NTOSLoader
/dev/hda3 COSIXLinux lilo (cosix)
/dev/hda7 RedHatLinux grub (Redhat)
2. Redhat 的lilo配置
# Redhat linux的lilo装载/dev/hda的MBR
prompt
timeout=50
default=win2k
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
message=/boot/message
lba32
#启动REDHAT LINUX
image=/boot/vmlinuz-2.4.18-3
label=RedHat
initrd=/boot/initrd-2.4.18-3.img
read-only
root=/dev/hda7
# 启动win2k
other=/dev/hda1
optional
label=win2k
#启动COSIX LINUX的LILO
other=/dev/hda3
optional
label=COSIX
#引导grub
other=/dev/hda7
optional
label=GRUB
3. COSIXLinux的配置
# COSIX linux的lilo装载/dev/hda3
boot=/dev/hda3
map=/boot/System.map
install=/boot/boot.b
nowarn
prompt
timeout=50
bitmap=/boot/cosix-msg.bmp
bmp-colors=6,9,0,15,9,0
bmp-table=60,5,1,18
lba32
default=cosix
#启动COSIX LINUX
image=/boot/vmlinuz-2.4.18-5
label=cosix
initrd=/boot/initrd-2.4.18-5.img
read-only
root=/dev/hda3
vga=0x314
append="devfs=mount quiet 5"
# 启动开机时的LILO
other=/dev/hda
optional
label=LILO
# 启动WIN2K
other=/dev/hda1
optional
label=WIN2K
4. grub 引导
# 把grub装在/dev/hda7,执行grub-install命令
# grub-install /dev/hda7
default=1
timeout=10
splashimage=(hd0,6)/boot/grub/splash.xpm.gz
title RedHatLinux (2.4.18-3)
root (hd0,6)
kernel /boot/vmlinuz-2.4.18-3 ro root=/dev/hda7
initrd /boot/initrd-2.4.18-3.img
title COSIX
root (hd0,2)
kernel /boot/cosix-server-vmlinuz ro root=/dev/hda3
initrd /boot/initrd-cosix.img
title WIN2K
root (hd0,0)

title COSIXLilo

5.Win2k 的ntosloader引导
(1)制作win2k启动linux的启动文件
dd if=/dev/hda3 of=bootcosix.sec bs=512 count=1
dd if=/dev/hda of=bootlilo.sec bs=512 count=1
dd if=/dev/hda7 of=bootgrub.sec bs=512 count=1
把创建的bootcosix.sec, bootgrub.sec 和bootlilo.sec 文件拷贝到win2k的c:
（2）win2k中boot.ini的配置文件
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)
WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)
WINNT="Microsoft Windows 2000 Server" /fastdetect
c:ootcosix.sec="COSIXlilo"
c:ootlilo.sec="RedhatLILO"
c:ootgrub.sec="grub"
