    Ubuntu LTS 12.04 takes 15-20 minutes to boot

    Please help.

    My Ubuntu Precise Pangolin installation was booting up pretty fast, it takes about 10-15 seconds to boot until today.

    When I turn on my PC this morning it was taking a very long time to boot maybe about 5 minutes that I decided to press the reset button then encountered unknown file system and grub rescue error. But I was able to fix this by booting on the LiveUSB, check and fix the filesystem via gparted.

    I decided to purge grub2 and reinstall it, update grub and restart, because I was thinking that the boot time has something to do with grub.

    But the next time I boot, it took about 18 minutes for Ubuntu to boot!!!
    I don't know what could be the problem.
    I do not see any error messages on the screen.
    Just the Ubuntu logo and the dots indicating that it is booting.
    Can someone please help me????
    I really don't want to reinstall Ubuntu.

    Why not reinstall? Maybe if you boot it from the LiveUSB again and try the recovery installation mode, the problem may be fixed.

    I was able to boot, in fact I am running Ubuntu now, but it took about 18 minutes or so before I was able to get to my desktop.

    I only purged and reinstalled grub while running Ubuntu. I was afraid of rebooting again cos I know it will take me that long again to be able to use Ubuntu.

    I don't want to reinstall the entire OS.

    Well then, you should check whether you have any problems with your hardware??????????(Just a wild guess)

    Boot up, and right after boot up run

    Code:
    dmesg > ~/dmesg.t
    Then copy/paste the contents of the new dmesg.t file in your home directory here, between [CODE] tags (the hash symbol on the editing toolbar).

    +1 on cortman suggestion.

    But you may be able to review dmesg and see if there is a long time between entries. Or some entry posted multiple times and then timing out. You could then just post that part.

    Every 40 or so reboots it also does a file check fsck or e2fsck to verify file system. With ext4 that check goes very fast, but if ext3 or ext2 it may take a while.

    Re: Ubuntu LTS 12.04 takes 15-20 minutes to boot

    dmesg | less
    can let you look though things that happened during and since booting, but I am not sure how far back that goes until you lose the beginning (may depend upon memory).

    Otherwise look through /var/log/dmesg or /var/log/syslog for anything unusual or errors, especially anything related to drive access, if something got corrupted on a drive or a drive is acting up.

    But as mentioned, Linux fsck's drives occasionally during boot and unfortunately Ubuntu no longer provides indication of progress, and that could take awhile for a large partition.

    Press the left arrow or up arrow when this is happening this will give you a screen of what is going on. Also I say run
    Code:
    dmesg
    and look for any errors and what not dmesg gives us a list of what the kernel sees at boot time Hope that this helps.
