Thread: Resizing the boot partition in Ubuntu

  1. #1

    Exclamation Resizing the root partition in Ubuntu

    My boot partition(ext4) is of around 8 GB...Now I need more space on it. I am thinking of resizing it using Gparted live...Just want to know whether this is the right procedure or it would corrupt my installation of Ubuntu 11.04??

    Welcome to the forums.

    The resize of your boot partition is only one of the possible options.

    Please, open a terminal (Applications -> Accessories -> Terminal), type these commands and post the results:

    Code:
    sudo fdisk -l
    mount
    df -h
    sudo du -h --max-depth=1 /
    Best regards,

    Luis

    Re: Resizing the boot partition in Ubuntu

    Apparently you have no unallocated space on your hard drive. So you would need to shrink the 108 GB NTFS partition (/dev/sda5) before to enlarge your boot partition (/dev/sda6). Gparted (System -> Admin -> Gparted) is a good tool for the shrink operation. If Gparted it is not installed, type this command:

    Code:
    sudo apt-get install gparted
    If you wish to enlarge the boot partition, use Gparted too. But you will need to boot your system into an Ubuntu Live CD / USB.

    Gparted is a reliable tool but resizing operations are risky. So, consider to make a backup of your system before any change on your partitions.

    Best regards,

    Hmmm. You do not need any Gparted Live CD. Use a standard Ubuntu Live CD and select the option "Try Ubuntu" at startup.

    Then you will be able to use Gparted for resizing your Ubuntu root partition /dev/sda6.
