Normal.mod not found of Debian Stable (Jessie 8.1)

* * When you plan to reset the next default-brower, entered the dpkg-reconfigure results by a G, and press the tab, and finally lost the carriage return. it becomes

dpkg-reconfigure grub-pc

Enter the dpkg configuration GRUB-PC interface, the inside let the grip input linux-command-line, press the ESC did not expect to quit instead of the ", is the number 1 on the symbol. Next the next option is entered. This only has a OK to move to. Then knocked on the next bus. I don't care about it. I didn't expect to restart. The error is directly.

Tips

errorfile ‘/boot/grub/i386-pc/normal.modnot foundgrub rescue>

Most commands are not available, only a few simple ls,set can

This means that the normal module cannot be found. I don't have a livecd U-disk in my hand.

The following is the complete process of restoring grub, only for the reference of a friend under Debian:

rescue>ls(hd0, msdos), (hd0, msdos1), (hd0, msdos5)

Because my machine has only one hard disk, no partitions, so msdos1 is my home directory.

grub rescue>set root=(hd0,msdos1)grub rescue> ls /usr/lib/grub/i386-pc/normal.mod, xxx.mod search.mod ......grub rescue>setnormalgrub rescue>normal

So it's loaded on the normal.mod.

But it's not over yet.
Into the Grub

grub>vmlinuz vmlinuz-linux-headers-3.16.0.4-xxxxgrub>initrd initrd-linux-headers-3.16.0.4-xxxxgrub>boot

This place will be stuck for a while and then into Initramdisk.
In fact, this is because no other mod is found, causing the error.

Re-force shutdown, repeat the above operation.
Then changed a kernel, reported the following error

It's a good run. It means that these mods are not under/BOOT/GRUB/I386-PC.
So we went back to loading normal.mod at the very beginning, loading the missing mods once.

rescue>set prefix=(hd0rescuerescuerescuerescuerescuerescue>normal

These will have a normal majority of modules, into a not intact grub menu.list

Then choose one to go to the TTY, into the TTY will say more.
It would be nice to fix grub directly.

root>-l这里查看下你的硬盘, 我只有一块, 分了几个区. /dev/sda1, /dev/sda2, /dev/sda5, 说明挂载的是/dev/sdaroot> grub-install /dev/sdaroot> update-grubroot>-r now

After reboot. Logged in as normal.
