fedora 18 修改启动顺序

使用Windows + linux 双系统的用户可以使用如下方法修改启动顺序

1. 首先找到Windows的菜单menuentry.

# cat /boot/grub2/grub.cfg | grep Windows

输出：

menuentry 'Windows 7 (loader) (on /dev/sda1)' --class windows --class os $menuentry_id_option 'osprober-chain-58D89313D892EF0E' {
menuentry 'Windows 7 (loader) (on /dev/sda2)' --class windows --class os $menuentry_id_option 'osprober-chain-6CA09A83A09A5384' {

2. 设置Windows 作为默认的启动项(这儿只能使用上面命令输出中双引号  "  "  或 者单引号    ‘     ‘   中的内容)

# grub2-set-default 'Windows 7 (loader) (on /dev/sda1)'

3. 验证默认启动项  # grub2-editenv list
输出：saved_entry=Windows 7 (loader) (on /dev/sda1)
