What's happened is that grub has lost track of where your operating system is located.

You want to stop the process at the initial grub screen that shows you the choices of operating systems. If you don't see choices, press the Shift key from the beginning of booting until a menu appears.

Press c for command, and then start the process of looking for where the system thinks your OS is located. (Or, if you're sure you know, you can skip the various "ls" commands at the beginning.) (This is taken from Grub2 - Rescue Mode.)

At the grub> prompt, type

That will list all the drives and partitions which grub can look at to find an OS. (hd0) is the first drive. (hd0,1) is the first partition on that drive. You need to type "ls (hd0,1)" (without quotes) at the grub prompt and see whether there are files called something like "vmlinuz" and "initrd" there. I don't know what your setup is, so you may have a lot of partitions to check until you find the one you need.

Then go...

What you need to understand about initramfs is that it is a filesystem. Since kernel 2.6 it is, basically, the only kernel-imposed filesystem ( leaving aside VFS, which is arguably also a filesystem ) on your machine. Your initramfs image is a disk image.

Within your initramfs image will be whatever files your distribution decided were crucial enough to require before your root disk is found. Usually that's Busybox and whatever kernel modules you need to find and mount your root device. This is isn't working for you.

There's no real mystery here though, all things considered. If you can find your way around a terminal prompt you can navigate the initramfs. But first you've gotta demystify it.

First and foremost and once again - this is just /. It's Linux root doing Linux root type things. In fact, if it is in a separate file from your kernel, it's actually already your second root device. Every Linux kernel contains a basically empty / all its own which it...

Today I have learnt an important and brief Linux lesson fixing up the computer of one neighbourg -- a newbie to Linux world by the way and also a recent xanmod kernel user. Well, this is the story, the computer booted and dropped itself to an annoying 'initramfs busybox error' like this:


BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash)
Enter 'help' for a list of built-in commands.
# 'fsck' or 'exit' will give something like this
(initramfs) fsck
/dev/sdaX ... UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)
fsck exited with status code ...
The root filesystem on /dev/sdaX requires a manual fsck
# I can't remember now rigthly the whole info result
# indeed, the computer is unable to run the kernel

After several unuseful workarounds, the easiest solution that worked like a charm:


(initramfs) fsck /dev/sdaX
# where X is the number of that...
