下面介绍在GRUB引导下进入Linux单用户模式的三种方式:
硬件环境: intel P4 / 1G RAM / sata 80G 软件环境: 1)Fedora Core 3(以下简称为FC3)和Windows2000 advance server双系统。 2)LVM管理Linux分区。 3)/boot/grub/grub.conf文件内容:# 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 (hd0,2)# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00 # initrd /initrd-version.img #boot=/dev/sda default=1 timeout=1000 splashimage=(hd0,2)/grub/splash.xpm.gz hiddenmenu title Fedora Core (2.6.9-1.667)root (hd0,2)kernel /vmlinuz-2.6.9-1.667 ro root=/dev/VolGroup00/LogVol00 rhgb quiet initrd /initrd-2.6.9-1.667.img title windows 2000 adv rootnoverify (hd0,0)chainloader +1
首先,启动电脑,屏幕出现如下提示:
Press any key to enter the menu Booting windows 2000 adv in 999 seconds…
按任一键跳过计时,进入下一步:
GNU GRUB version 0.95 (639K lower/103924K upper memory) Fedora Core (2.6.9-1.667) Windows 2000 adv
下面是GRUB的提示:
‘e’ 在booting前编辑启动命令行。 ‘a’ 在booting前编辑kernel的参数。 ‘c’进入grub命令行。
由此按‘e’、a‘、’c‘三个不同的键,进入三种不同的操作:
一、快速法
选择Fedora Core (2.6.9-1.667)菜单,按a键:
grub appendro root=/dev/VolGroup00/LogVol00 rhgb quiet
修改成:
grub appendro root=/dev/VolGroup00/LogVol00 single quiet
