我把这里的splash去除了。这样开机就能看到那些开始信息了。

initrd /boot/initrd.img-2.6.32-21-generic

}

menuentry 'Ubuntu, with Linux 2.6.32-21-generic (recovery mode)' --class ubuntu --class gnu-linux --class gnu --class os {

recordfail

insmod ext2

set root='(hd0,1)'

search --no-floppy --fs-uuid --set d98561c1-62af-4753-b6f0-fbcfcb6a7541

echo 'Loading Linux 2.6.32-21-generic ...'

linux /boot/vmlinuz-2.6.32-21-generic root=UUID=d98561c1-62af-4753-b6f0-fbcfcb6a7541 ro single

恢复模式，是单用户模式。

echo 'Loading initial ramdisk ...'   ramdisk？输出这个信息做什么呢？

initrd /boot/initrd.img-2.6.32-21-generic  跟正常启动时的，是同一个文件。
