如果你是使用的grub作为主引导程序引导双系统(Windows & Linux)的话,可以通过以下操作把windows设为默认启动的操作系统,调整两个操作系统在屏幕上的显示顺序(一般情况下grub把linux设为默认启动,而windows显示为dos): 1. 用root账户登陆到linux 2. vi /etc/grub.conf,grub.conf的内容如下 # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You do not have a /boot partition. This means that # all kernel and initrd paths are relative to /, eg. # root (hd0,4) # kernel /boot/vmlinuz-version ro root=/dev/hdc5 # initrd /boot/initrd-version.img #boot=/dev/hdc default=0 timeout=10 splashimage=(hd0,4)/boot/grub/splash.xpm.gz password --md5 $1$sefuvF4T$uet8lieX0oTII1lsnZGLJ/ title Red Hat Linux (2.4.20-8) root (hd0,4) kernel /boot/vmlinuz-2.4.20-8 ro root=LABEL=/ initrd /boot/initrd-2.4.20-8.img title DOS rootnoverify (hd0,0) chainloader +1 3.修改grub.conf文件就可以解决启动顺序问题,修改后的文件如下 # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You do not have a /boot partition. This means that # all kernel and initrd paths are relative to /, eg. # root (hd0,4) # kernel /boot/vmlinuz-version ro root=/dev/hdc5 # initrd /boot/initrd-version.img #boot=/dev/hdc default=0 timeout=10 splashimage=(hd0,4)/boot/grub/splash.xpm.gz password --md5 $1$sefuvF4T$uet8lieX0oTII1lsnZGLJ/ title DOS rootnoverify (hd0,0) chainloader +1 title Red Hat Linux (2.4.20-8) root (hd0,4) kernel /boot/vmlinuz-2.4.20-8 ro root=LABEL=/ initrd /boot/initrd-2.4.20-8.img
