linux重新安装丢失的内核
核在引导时，GRUB 列出了下列错误信息。
...
kernel /vmlinuz-2.6.32-71.el6.x86_64 ro root=LABEL=/
Error 15: File not found

进入救援模式： boot: linux rescue

简单看了一下/boot 文件，确定有了新的内核。
bash-4.1# ls /boot
config-2.6.32-71.el6.x86_64 lost+found
efi symvers-2.6.32-71.el6.x86_64.gz

initramfs-2.6.32-71.el6.x86_64.img vmlinuz-2.6.32-71.el6.x86_64
然后退出了chroot Shell，接着退出了救援模式，重启后，GRUB 成功地找到了新内核。
