Ubuntu :: Booting Into BusyBox Built-in Shell
Jun 30, 2011
As far as I know the power went out once and my computer might have been on - now Ubuntu won't boot correctly. It boots into 'BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash)'.
Code:
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn't have requested /sbin/init.
No init found. Try passing init= bootarg.
BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash)
Enter 'help' for a list of built-in commands.

We rebooted the server and getting:
BusyBox v1.1.3 (Debian 1:1.1.3-5ubuntu7) Built-in shell (ash)
Enter "help" for a list of built-in commands.
(initramfs)
When we boot from the live CD to run fsck manually, it cannot find the hdd partition. It's using Lilo boot loader.

2 days ago I turned my computer on and I could not enter to desktop as usually. The computer showed a message on a black screen that ended with: BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu1) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs)
I couldn't do anything else. I don't want to loose my not backed up info. I googled the error and I found that I could boot from a live cd so I downloaded Ubuntu 10.10 and boot it from livecd... Now I am running firefox from livecd trying to fix this error. I note that /dev/sda1 my main partition is not mounted, so I have tried to mount it from gparted and from terminal and I am unable to do it... I don't know if the error I am getting on when booting is because of sda1 is unmounted, I found a similar case here [URL] but "bcbc" user recommend me to open a new post.

I did the update from within 9.10 to 10.4. Now when Ubuntu boots up, something happens and it goes to busybox. I tried sitting there and waiting, but nothing happened. So I tried typing exit, and then about a minute or two later it finally finished booting.
It's real nice that everyone else is reporting 20-30 second boot times, but before with 9.10 my boot time was around 60 seconds or so, and now it's around 5 minutes. So how can I fix this? Is there a way to post the boot log here? Where would it be located at on my computer?

I was upgrading our lab's dhcp server to Lucid and it totally died. I have it running on a Debian recovery cd right now. I ran into a bug in gtk which I seem to have fixed, but now I have more serious errors. If I boot without a CD, I get dumped into a busybox shell after the machine fails to boot. From the live CD, I tried dist-upgrading again and it dies trying to build and install rsyslog with a broken pipe error. I am at a loss as to what to do from here short of reinstalling (which is the last option as this server has a lot of custom configs on it)

I've been working on creating a Live CD with the tools I want, just for my use with system recovery and repair. For the most part, things have gone very well. The Live CD actually works fine, somewhat. I have run in to a problem where it doesn't actually boot on a lot of hardware.
What happens is during boot, while the modules are loading, the boot process hangs and the disc drive spins down. While I thought it might be a kernel problem, I'm using the .config from the latest gentoo Live CD, which boots fine on the same hardware.

I have never in a year had a problem with this d-boot system. Two days ago I tried to boot into ubuntu like every day. It started to load normal, went to the ubuntu logo and paused for about 15 seconds and posted this under the logo:
One or more of the mounts listed in /etc/fstab cannot yet be mounted
/: waiting for /dev/loop0
/tmp: waiting for (null)
/boot: waiting for /host/ubuntu/disks/boot
Press ESC to enter a recovery shell
I have looked everywhere and tried so many things, I can't look any further. All I have been doing for two days is trying to boot this system.

I have installed ubuntu desktop (not server) because some users want to access the gui (because of their applications). Now what I want to manage is: 1- boot the system in shell mode. 2- if someone want, use startx command to enter graphic mode for his own. otherwise he can continue to use pure terminal shell.
Is it possible to do such thing? how?

I am working on a embedded target board which runs on linux. The target board is connected to a linux machine through serial port. To bootup the target board, I run the minicom in the linux machine, boot the kernal of the target board through giving the boot command through the serial console (minicom). Now the question is when the target board boots up, it doesn't starts a shell. The rc scripts are getting executed. There are target specific applications getting started from the rc scripts. I appended & to the last launched application. Still I don't get shell prompt.

I installed all recommended updates as suggested by the update manager, after installing was asked to restart. During this restart I get the error message "udevadmin trigger is not permitted while udev is unconfigured. After this I am left with a BusyBox v1.13.3 [...] (initramfs)_

Last week I took up the courage to replace my windows 7 completely with Ubuntu 10.04 (Lucid). The Installation went fine and was happy with it.
And then on 10th I upgraded from 10.04 to 10.10 (so called perfect 10), when the laptop restarted it showed me BusyBox v 1.15.3 message on the Boot screen.

I've been having a problem with this "BusyBox", and unlike windows, my files are not able to be "stolen" to another operating system. I need to get my files back from /home back.

I've tried both the DVD and CD, the CD with both usb-creator-kde and unetbootin. The results are the same always, the USB boots, into the splash screen, I select Start Kubuntu, it goes to the loading screen. After some seconds it starts scrolling a wall of text, gives some error about not being able to write or read /root/var/* because they don't exists and end up on a BusyBox with (initramfs) prompt.
I need to install the system on a new disk (2tb) instead of upgrading because I have to send the current one (1tb) to replacement. Could the large 2tb disk be a problem? I tried unplugging all disks and leaving just the disk I want to install to, but no deal... (both are SATA).(Checked the md5sum and they both match for DVD and CD...)

I either installed Hardy heron or its predecessor by accident, but began running it exclusively. I did it way back when while trying to create a test drive disk, and I did not repartition the drive, because all my windoze NT stuff survived. I'm now 8.04. Yesterday I had a bunch of updates to do, did them, closed a ton of windows and then pulled up 3 open office files and each, when it came up said there wasn't enough space to save all needed information as they opened. I then closed them and one hung and froze the whole machine, leading me to do a reset. This is BEFORE rebooting from the updates.
Now when I boot into Ubuntu (I'm dual boot) I start to get the opening Ubuntu GUI screen but then get :
BusyBox V1.1.3 (Debian 1.1.1.3-5ubuntu12)built in shell (ash) line followed by:
initramfs)
I'm essentially a total noob, I've rarely used command line and not for a long time. I made a version 11.04 live disk, and it says that the file system is clean, but will not show me any of my old files, only the NT files and directories. I have a ton of unbacked up important data in Hardy Heron so I don't want to do an install from the 11.04 CD.
I've read several threads so far, and can't seem to find anything addressing this that I understand. The drive is a 160GB drive on an HP Pavilion dual core that has a 154GB NTFS boot partition, which is where I'm sure the Hardy Heron files are, and a 6GB FAT32 HP_RECOVERY partition that windoze lists ad drive D (the NTFS is C) The live disk says the FAT32 partition is /dev/sda1 and the NTFS is /dev/sda2
Where should I start? I've seen stuff about booting into recovery mode, but that isn't an option when I boot from the hard drive, and the only older ubuntu disk I have is for 7.something and generates "defective CD" type error messages.

I've got Ubuntu 11.04 on a 40G hard disk in dual boot with a Windows XP on a 300G hard disk.
I've got back data with an USB key from a broken Windows Seven, then I've shutdown my ubuntu, but it has difficulties to stop (a mp3 player, which doesn't work well, has already damaged my Ubuntu previously). Then my Ubuntu doesn't manage to boot : it launches "Busy Box" with "initramf". When I boot in recovery mode it fails to boot something at 5s then it tries to launch something constantly.
I've launched a live CD in order to recover my data, but when I try to mount my hard disk I get :
Code:
I've found this link about this problem : [url], but it's too complicated for me.
I just want to recover my data, a system reinstallation wouldn't bother me.

As the name says, I'm new to Linux. I've never even seen Linux. Super noob. I have installed Ubuntu 10.04 onto a Dell Dimension 2350 P4 1.8ghz, 1g ram, GForce 4x 128mb video card running XP. I installed from a Live CD and rebooted. The screen says "finishing Ubuntu install" does a countdown and loads into BusyBox instead. This is what I see:
BusyBox v1.1.3 (Debian 1:1.1.3-5ubuntu7) Built-in shell (ash)
Enter help for a list of built-in commands.
(initramfs)cannot mount /dev/sda1/tmpmountpoint
If I boot from the CD I get: Unable to find a medium containing a live file system I'm stuck, I don't know many commands so step by step. Simply saying 'load grub' means nothing to me.

I'm recieving a BusyBox v1.13.3 screen after attaching my 2nd sata-harddrive. I bootup the pc, but can't get to the login screen because of this message: Gave up waiting for root device. Common problems:
-Boot args (cat /proc/cmdline)
-Check rootdelay= (did the system wait long enough?)
-Check root= (did the system wait for the righ device?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/bf2ed1f9.... does not exist. Dropping to a shell!
[code]....
It seems one thing to do is to edit my /boot/Grub/menu.lst but I don't have that file! Even with the command: gksu gedit /boot/grub/menu.lst it just opens up an empty box. Note, the 2nd hdd (sdb) has to be removed to properly boot into Ubuntu to browse my files.
Starting a live-cd (9.10) and mounting the /root partition from sda method doesn't work either because the partiton is not mountable in Palimpset due to it not having a any readable data on it! ps. going to try and get into the Grub Loader during bootup and see if I can add "all_generic_ide" to the end of the assigned /root line. Will get back in a bit.Grub screen doesn't even appear if I attach the 2nd harddrive so can't get into that.

On a small Linux appliance using Busybox to provide the usual suspects, I'd like to create an alias "ll" that would translate to "ls -al" like I'm used to. Apparently, "alias" is not part of Busybox:
Code:
> echo $SHELL
/bin/sh
> ls -al /sbin/sh*
lrwxrwxrwx 1 1000 1000
7 Jan 1 2007 /sbin/sh -> busybox
> alias ll='ls -al'
alias: not found

recently attempted to upgrade to Lucid Lynx but it's not booting up. it just shows "Gave up waiting for root device" and drops to BusyBox. waiting doesn't do anything. i see the GRUB options but none of the 3 10.04 LTS's boot up. i've read a number of threads but i don't think my Ubuntu drive is being read. i say this 'cause cat/proc/partitions doesn't list my Ubuntu drive/partition. Also when booting up in the Live CD, GParted only lists the Windows partition. neither does sudo fdisk -l.

issue is with 10.04 installed via wubi on a xp pro ntfs drive.Have setup a new installation of 10.04 and been running it a few months.Update Manager came up and I said ok.Then after rebooting, this is what I get and I have found many SIMILAR but CONFUSING threads, so I don't know where to go from here and how to fix it.Grub flashes, and then this is what I get:Mount is denied because the NTFS volume is already exclusively opened.Use the fuser command.
Could not mount the partition /dev/sda1
run chkdsk /r
(filesystem = ntfs, error code = 16)

I'm running Ubuntu 10.04 i386 on a K9M6PGM-2 mainboard with an AMD Phenom Triple core @ 2.3 gig. I have 2 gig of RAM and Lucid is on a 320 gig HDD, /dev/sda1 shared w/Win XP. I have in the SDC position an 80 gig with Ubuntu Karmic. Long before the Widows was installed this problem annoyed me. My hope was that by wiping GRUB out and rebuilding it from the Live CD that this problem would be fixed but after several boot process' the problem ihas returned.
When I boot into Karmic and look at /sbin I find the file init but of course cannot open it. Is there any way to fix this?
The nachine might boot into Lucid 3 or 4 days in a row with no problem and then refuse to boot anything but WinXP or Karmic. It seems not to be the GRUB as Wendoze and Karmic boot as expected.
At the /dev/sdb I find;
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 9327 74919096 83 Linux
/dev/sdb2 9328 9729 3229034+ 5 Extended
/dev/sdb5 9328 9729 3229033+ 82 Linux swap / Solaris
and do not know the origin of the partition.

Prior to posting this I entered search arguments, "Busybox," then "initramfs" to attempt to find another user who may have experienced the same thing; if the solution is imbedded in the message threads, I must have missed it. On hand is a Ubuntu Server 8.04.3 installer CD. What works: Installs to a Mac Pro under both Parallels, and then under Fusion both were successful first try.
Install to a newly purchased 2 gig Acer Aspire One seems to have succeeded, but upon launching from Grub, Busybox/initramfs intercepts and halts the launch with an error I don't understand:
Starting up ...
Loading, please wait ...
Check root = bootary cat /proc/cmdline
[code]....
The new Acer-PC Aspire One was partitioned into four 80 gig partitions using the Paragon software to do the partitioning. XP is on the first, and Ubuntu Server on the next 80 gig partition. Install was "successfully" done from a Lite-On external CD/DVD over USB.
During the install I changed the default name from Ubuntu to something else (probably a bad idea), and I naively entered "/" root to answer the mount question (finding nothing to tell me what to do). Ubuntu required a disk driver choice from a long list - finding no reference or guidance as to what to enter, I naively entered IDE Generic, and it took (I guess it "took").
FWIW the Ubuntu installer didn't require me to indentify the mount entry or the disk driver during installs on my Mac (Fusion/Parallels).I did connect the Internet during the install. I did checkoff/install LAMP during the install from CD. Goal: To use Joomla in a mock server environment.

Why use nash instead of busybox in initrd and initramfs? I'm just looking for pros and cons of both really (and any other applications with similar functionality). I'm currently leaning towards busybox being the better option, why redhat and fedora use nash in their initrd.

I have downloaded the latest Ubuntu 9.10 and used 'U904p' a program I had for creating 9.04 live USB I had before. I had 9.04 on the USB pen but thought that 9.10 would be better to install right away rather than upgrading it. So I run through the CLI and make it bootable and all that. I come to put in my pretty old (Spare parts mashed together) Linux box. I get this about 1 minute after the Ubuntu logo and loading bar:
Top of page: WARNING: Couldn't open directory /lib/modules/2.6.31-14-generic: No such file or directory
Then lots of 'FATAL: Could not load /lib/modules/2.6.31-14generic/modules.dep No Such file or directory'
Then I am dumped in to Busybox in initramfs command line. I have been googling and look around the forums all last night and this morning. I find loads of stuff from 9.04 but not 9.10? I tried the old 'Pull USB pen when Ubuntu log shows' and 'Changed SATA settings' turned them off in end, using IDE. Could it be that I created it using the old U904p program. I will look in to the newer one. Seen it about on forums. Otherwise any ideas? I am wanting to build a FOG box for imaging all my PC's and trailing it for work.

I have a Linksys WRT54G with the Tomato firmware on it. So the system running on the router is Busybox 1.14., which as far as I know is Linux-based. I want to update the busybox to the newest version, using ipkg which is the only package manager it has installed on it. By the way, I use telnet to access the router. So I use # ipkg install (the url to newest busybox release) but at some point it stops and says:
mkdir: cannot create directory '//opt/usr/': Read-only file system
so what can I do? How can I make the filesystem read-write?
