    Hi everybody :)

    I'm on ubuntu, and not a super pro in linux...

    To learn new stuff I decided to learn about fdisk, grub, and test other distro


    I really dont want to break all my partition during the operation.

    could you help me on with this please :)

    Code:
    nazukia@machine-code:/home/nazukia/fdisk /dev/sda
    
    Command (m for help): p
    
    Disk /dev/sda: 1500.3 GB, 1500301910016 bytes
    255 heads, 63 sectors/track, 182401 cylinders, total 2930277168 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x000460c2
    
      Device Boot      Start        End      Blocks  Id  System
    /dev/sda1  *        2048  2905128959  1452563456  83  Linux
    /dev/sda2      2905131006  2930276351    12572673    5  Extended
    /dev/sda5      2905131008  2930276351    12572672  82  Linux swap / Solaris
    
    Command (m for help):
    
    I think that I have to reduce the size of sda1 ? and create a new partition after?

    Thank :):oops:

    So you want to dual-boot, but you need to make another partition. Right? You could use Gparted to partition and format, or must you use the command-line for some reason? Personally, I would recommend using a Gparted livecd. Typically, a Linux distro needs at least 20GB of disk space. With you having about 1.5 terabytes, you can divide your hard-drive how ever you want.

    Is that an extended logical partition? Are you dual-booting with Windows? You may want to get rid of the extended partition and make it a regular partition, or do you have a specific reason for keeping it?

    I dont have window anymore, I dont dont want to anymore hehe.

    I dont know what is that :
    Code:
    /dev/sda2      2905131006  2930276351    12572673    5  Extended
    Maybe a left over from window ?... (I use to have it)

    I really want learn command line and get better at this. I prefer the hard way

    oh my good arochester,

    that wasnt that easy to understand.

    I ends up reading about hard drive partitions table type all a lot of super interesting stuff :) more I learn, more I like hihi...

    I didnt to my dual boot yet, I really want to make sure I didn right. but whatever, what I just learn have more value thant this dual boot :)

    It would assist us in helping you by telling us about your hardware.
    Code:
    lspci
    Also, if not wanting windows and wishing to learn command line, why not rebuild the partition table after using either shred or the dd command?
    Code:
    man shred
    See in the dd wiki the sections Disk wipe and Creating empty files of arbitrary size

    If using gparted, I would suggest first deleting all partitions and then creating one partition for the entire hard drive and formatting it to ext2 and after this create your partitions using a journaled file system, like ext4 (except for the swap, of course).

    Welcome, nazukia! It is good to see someone willing to learn in the old school way!

    Its definitively what i want. I acually dont have window... I used too but install ubuntu from a Cd and wipe window when I did it.

    Unfortunaly I didnt tough about partition when I did that, so Im stuck with 2 partition

    1 for linux at /
    1 for the swap

    It would assist us in helping you by telling us about your hardware.

    there is what I get from lspci

    Sorry it took long time to get back -- life interfered!
    lspci command shows your machine uses a 2nd generation Core processor, Atheros wireless and realtek ethernet cards, AMD audio and graphics -- just for curiosity

    As above,
    If using gparted, I would suggest first deleting all partitions and then creating one partition for the entire hard drive and formatting it to ext2 and after this create your partitions using a journaled file system, like ext4 (except for the swap, of course).
    The alternative is an overnight or longer wait after issuing the command (as root)
    dd if=/dev/zero of=/dev/sda bs=4096 conv=notrunc,sync
    One big goal is to do a clean install, especially when planning on installing Slackware. So, don't be afraid to wipe it out and start over -- the hard drive, that is.

    Then, after either using gparted and/or the dd command, create your partitions.

    Hi :)

    thank for the answer !


    I want to keep my ubuntu one. :
    /dev/sda1 * 2048 2905128959 1452563456 83 Linux


    But like we see this partition is to big for nothing


    my plan, and im supe affraid to do it.


    1- wipe my swap partition (its 8 gig)

    2- with the free space (use a 3gig as a new partition for a backup)


    3- use the last five gig to create another primary partition and install slacware on it


    4- change grub from sda1 to allo dual boot on the new sba2 (slackware)


    5- Boot from slackware and find the best way to resize the size of sda1


    What do you think?

    It appears your swap is located within an extended partition and sda1 is overly large.
    I would suggest leaving the swap alone for now.

    Use gparted to shrink /dev/sda1 to a reasonable size -- as Devyn says, 20-25 gigabytes -- first.

    After shrinking /dev/sda1 with gparted, take a snapshot of the graphics gparted shows for the partitions and the hard drive space. Let us see it, please.

    One step at a time may be best for you to understand what is going on.

    Must go now and attend to business. Shrinking such a hard drive partition will probably take some time. I'll check back in a few to several hours.

    Your are doing a good job, just stick with gparted for now.

    You should perform the shrinking from a live disk.

    Use Gpart tool for ubuntu, it's easier.

    @Shailendra Patel -- easier is not necessarily better; in addition, OP originally stated "the hard way" is a preference and goal is to install Slackware (not what most ubuntuites want).
