    Ubuntu 14.04 boot problems

    Installed Ubuntu 14.04 and rebooted and the screen goes black and says:
    mounting /dev on /root/dev failed: no such file or directory
    mounting /sys on /root/sys failed: no such file or directory
    mounting /proc on /root/proc failed: no such file directory
    Target file system doesn't have requested /sbin/init.
    No init found. Try passing init=bootarg

    I used a USB to install Ubuntu so I plugged the USB back in and tried an older kernel and didn't work. I have also tried to get into Ubuntu using the try ubuntu without install option and it just sticks to the purple load screen. I have also tried going into the boot parameters and changed ro to rw and quiet splash to nomodeset and then combined the two but still couldn't get into the desktop to run the terminal.

    Re: Ubuntu 14.04 boot problems

    bpashuta; Hi ! Welcome to the forum .

    Looks like no operating system is found in the booting process.
    So, what have you got for that initial booting medium > Are we looking at UEFI and the efi interface is not set up correctly ?

    OR is this system booting with the legacy bios to Master Boot Record ?
    Is ubuntu the sole operating system installed ? No ? Which system controls the booting process ?
    Is there more than 1 hard disk installed ?

    Can not boot the liveDVD even with the "nomodeset" boot option might indicate that you do have a UEFI system and also maybe 'secure boot' in force ?

    Talk to us and advise us of what booting arrangement we are dealing with here.
    a world of possibilities
    we are looking for that one

    Re: Ubuntu 14.04 boot problems

    Ubuntu is the only OS on the hard drive and there is only one hard drive installed. I've gone into grub2 to get more information out of the HDD and these are the inputs and outputs that I get:
    grub> ls (hd0,msdos1)
    Partition hd0,msdos1: Filesystem type ext* - Last modification time 2014-04-27 02:56:00 Sunday, UUID 13b53e35-f525-4168-93ab-e27112276202 - Partition start at 1024 Kib - Total size 973882368KiB
    grub> ls (hd0,msdos1)/
    lost+found/ etc/ media/ var/ boot/ home/ mnt/ opt/ root/ run/ srv/ tmp/ usr/ initrd.img.old cdrom/ ubiquity-apt-clone/

    Re: Ubuntu 14.04 boot problems

    bpashuta; Welp.

    The boot code has been found, and a file system identified. Are the system boot files available ?

    From that grub prompt, what returns:
    Code:
    ls -la (hd0,msdos1)/boot/grub/grub.cfg
    ls -la (hd0,msdos1)/vmlinuz
    ls -la /initrd.img
    Now if all the above have positive results, try and boot:
    Code:
    linux (hd0,msdos1)/vmlinuz root=/dev/sda1 ro
    initrd (hd0,msdos1)/initrd.img
    boot
    else we are going to consider (RE-)installing grub from the liveDVD.

    maybe yes
    but I do expect no

    Re: Ubuntu 14.04 boot problems

    bpashuta; Welp.

    Like I advise, not unexpected, just to make sure was all.

    OK, let's try and re-install grub from the liveDVD:

    Boot up the liveDVD to terminal:
    Terminal commands:
    Code:
    sudo mount /dev/sda1 /mnt ##because sda1 is where the 'root' file system is installed to
    sudo grub-install --boot-directory=/mnt /dev/sda ##because we want the boot code installed to the MBR of that hard drive
    sudo umount /mnt ##because we are all done
    Reboot and reset bios to boot the hard drive.
    what now results ? If all boots good. Make sure all stays good ->
    Code:
    sudo apt-get update
    sudo apt-get upgrade
    sudo update-grub
    when the going gets tough
    the tough get going

    Re: Ubuntu 14.04 boot problems

    Okay...when I boot up the laptop using my USB I go into the advanced menu and click on try ubuntu without installing this time. Now, I'm getting stuck on the purple ubuntu loading screen and when I press ESC to find out whats going on I get:
    stdin: Not a typewrite
    stdin: Not a typewriter
    stdin: Not a typewriter
    umount: can't umount /cdrom: Device or resource busy
    /init: Line 7: can't open /dev/sr0: No medium found

    That repeats like 4 more times then I get this.
    mktemp: No space left on device
    cp: write error: No space left on device
    cp: write error: No space left on device

    Re: Ubuntu 14.04 boot problems

    bpashuta; Yuk !

    That is beyond anything I have experienced, I have no idea what is not taking place.

    Is this a viable thing you can do -> burn to a DVD ?

    Maybe that USB write is bad ? -> and thus the install was bad ?
    Check the .iso :
    https://help.ubuntu.com/community/HowToMD5SUM
    http://www.linuxquestions.org/linux/...sum_in_Windows

    Burn the .iso as an image (NOT data !) at the slowest rate:
    https://help.ubuntu.com/community/BurningIsoHowto

    Boot that liveDVD to the boot options menu and verify the Burn -> "check disk for defects".


    Off topic: I am going to go do yard work ( mowing), I will be back in about 3 hours.

    where there are solutions
    there are no problems

    I can't burn a DVD at this moment because I just have the one laptop right now but once I get a Bootable DVD and do the above steps I will get back in touch
