    Reducing partition size?

    Hi all,

    Quick question about partition sizing - or more to the point reducing a partition.

    Got a nice fresh build running a dual boot windows/Koala. It's a 1.5tb drive, so I gave 500 to Windows (I promise I only use Windows for games ...honest) and the rest to Ubuntu.

    But now I have burg running with it's shiny boot menu, I was thinking how nice it would be to have another OS on there (maybe play around with osx86 for example).

    However, I didn't think to leave any spare space ...D'oh!

    So, looking at the larger Ubuntu partition, can I now re-size that, so that I can give this potential new OS some room to play?

    Device Boot Start End Blocks Id System
    /dev/sda1 * 1 54918 441125968+ 7 HPFS/NTFS
    Partition 1 does not end on cylinder boundary.
    /dev/sda2 54919 182401 1024007197+ 5 Extended
    /dev/sda5 54919 182027 1021003011 83 Linux
    /dev/sda6 182028 182401 3004123+ 82 Linux swap / Solaris

    (On another subject - is that cylinder note there something I should look at?)

    I've got Gparted installed, but all the options for /dev/sda2 are ghosted ...which I kinda think may answer my question - but thought I would ask anyway

    It is a fresh build, so scrubbing and starting again would only be an annoyance rather than a problem - so that's my plan B

    Any ideas or thoughts gratefully received

    Cheers,
    Zippy

    it sounds like you have sda2 mounted.

    you need to use gparted from a live cd so all your partitions on the hard drive aren't mounted

    It will be difficult to unmount you running partition. You will want to use a live cd to do the resize.

    All partitions I have ever created with windows, show the same error complaining about cylinder boundry.

    Once you reduce the size of you linux / partition, I would recommend leaving some free space for future installs...

    Cheers.
    Nothing is ever easy, but if it is difficult you must be doing it wrong.

    This really has nothing to do with server platforms, moved to General Help

    Completely forgot about the live CD - nice one, I'll give that a try.

    Re: Reducing partition size?

    Partition planning is important especially if installing multiple operating systems. If just installing Ubuntu many recommend the separate /home to make it easy to upgrade, but you cannot share /home (or any other partitions like /boot) with other installs. But you can easily share all your data which is most of the space you use.
    I so far have just 3 20GB partitions for ubuntu, last install, current install and new beta for testing next install. When I set this up I did create a /home but it is only 1GB in a 50GB partition as I ended up creating the separate /data partition. I will eliminate the /home on the next update since I can easily backup a 1GB /home and reinstall on a new version. I hide the mount of /data and link everything into /home so all my data is easy to use.
