    Initramfs boot error

    Okay, so on occasion when I boot into ubuntu I get this error

    [mount: mounting /dev /root/dev failed: no such file or directory]
    [mount: mounting /dev /root/sys failed: no such file or directory]
    [mount: mounting /dev /root/proc failed: no such file or directory]
    [Target filesystem doesn't have /sbin/init.]
    [No init found. Try passing init= bootarg]

    [BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash)]
    [Enter 'Help' for a list of built-in commands.]

    (initramfs)

    I have no idea why this happens, and I get the error when I open any of the kernel versions or any recovery mode. Ubuntu 10.10 Desktop is the only OS installed on the computer, which is a Lenovo S10-3.

    I can eventually get it to go away, sometimes by repeatedly unplugging it and plugging it back in, and sometimes I will boot into GParted, do nothing, then restart and it will work.

    I have found some solutions online, but all of them involve the error happening as a result of dual booting with Windows.

    I have made no major system changes recently, so I can't see anything like that being the problem.

    If anyone know what's wrong or how to fix the issue it would be a great help. If anyone needs any more information, I can do my best to provide it.

    Re: Initramfs boot error

    It seems like...
    your kernel and initramfs were read and started, but cannot mount the correct root partition.

    Boot with LiveCD and mount the partition where ubuntu was installed on, by clicking the proper partition from "Places"->"Removable media".

    Open
    boot/grub/grub.cfg
    or
    boot/grub/menu.lst
    and find the line starting with "linux" or "kernel".
    Please post what comes after "root=", by openning this page with FireFox.
    For example,
    root=UUID=*******************

    "Application"->"Accessory"->"Terminal"
    and execute the following command in the openned window.
    Code:
    sudo blkid
    sudo parted -l
    Post the result, by openning this page with FireFox.

    Even i had the same problem recently..I did the

    fsck: Device or resource busy while trying to open /dev/sda2 Filesystem mounted or opened exclusively by another program?
    where sda2 is my partition number but to no avail..finally I've solved the problem and now my Ubuntu 10.10 is running smoothly again.
    Here is what I did:

    1. Download Gparted from http://sourceforge.net/projects/gpar...3.iso/download
    2. Burn it into a CD and boot from it.
    3. Now run the sudo fsck /dev/sdaX where X is the number of your partition in which you have installed Ubuntu (as it was 2 in my case)
    4. Since you have run this command from the Gparted Live CD,the Filesystem gets mounted automatically and what follows after the fsck command is a series of prompts that can be answered yes by pressing the Enter key
    5. Complete the steps above and then restart your system (dont forget to change the boot sequence back to your HDD from CD)

    Hope this helps you out..Do post your outcome..Beg your pardon if I have bad forum etiquette and explanation methods but I'm a complete newbie here..Good luck..

    Re: Initramfs boot error

    i have exactly the same problem but also i cant boot from any live cd or live usb. Also when removal the hard disc from my laptop (aspire 5600) then boot normally from live cd.

    i placed the hard disc as external to another pc and showed it up but i cant get into it. i received this message "unable to mount 117 gb filesystem"

    as a result i cant access into hard disc

    i don't need archives from hard disc i want just clean the disc and install again ubuntu

    any ideas ?

    thank you

    Re: Initramfs boot error

    Hai all,

    I have compiled the kernel 2.6.25 source code from www.kernel.org.After compilation ,when i am trying to boot my image(kernel image),i got below errors.

    Please let me know the solution for this problem ......

    Note:I followed grub.cfg and initrams steps.

    "by_uuid" and "33e3e/e4" are typo, are not they?

    If they are not typo, correct the line in /boot/grub/grub.cfg or /boot/grub/menu.lst, so that root partition is correctly mounted at boot time.

    As is written in above #3 and #4, file system check (and repair) by "fsck" may solve your problem.

    Or you may need some modules to mount your root partition. If so, incorporate them into initramfs (initrd).
    You can boot with Ubuntu live cd and "chroot" and add the necessary module names in /etc/initramfs-tools/modules and execute "update-initramfs".
    For details, execute
    Code:
    man chroot
    man update-initramfs
