    Question Need advice on how to install Ubuntu without erasing everything on my hard drive

    Hi,

    I need some advice, please, on how to install Ubuntu Studio on my machine without loosing data. After watching video tutorials and reading about clean installations, I'm still not 100% sure how to go about it.

    Currently, I'm running Win and the hard drive has 3 partitions (1xWin + 2xpersonal).

    I would like to get rid of Win altogether, no dual boot, and install Ubuntu on the partition Win occupies now. Without touching/ formatting the other two personal partitions in the process.

    Can someone, please, point me to a very detailed tutorial or write accurately the steps I need to take safely install U Studio without loosing personal data?

    Many thanks,
    Adrian

    @adido, welcome to the forum!

    What you want to achieve should not be too difficult, but a couple of comments first. Since you are wanting to preserve your personal data, back it up before you do anything. Replacing the partition Windows is on with Ubuntu and leaving the other two untouched is fairly straightforward, but any manipulation of partitions involves a slight risk of something going wrong with consequent loss of data. Backup now.

    The other comment - your two personal partitions will be formatted either NTFS or FAT32, probably NTFS. Although Ubuntu can read-write NTFS reliably, I advise you not to use this filesystem if you do not have Windows available. NTFS is a Microsoft filesystem and needs the utility chkdsk in the event of filesystem damage. Although there is a Linux utility for fixing NTFS, it is nowhere near as comprehensive as chkdsk.

    We need to see exactly what your partition layout is like before recommending something. Boot up your Ubuntu Studio live DVD or live USB (if you have one) and do one of the following. Either open Gparted, the partition editor and take a screenshot of the open window. In Ubuntu you would use the alt+PrintScr key combination for this. I don't know whether this key combo works in Ubuntu Studio as I'm not sure offhand which desktop environment Studio uses. If you can't get a screenshot, open a terminal and post the output of these two commands:

    Code:
    sudo fdisk -lu
    sudo parted -l
    Sorry to throw a couple of terminal commands at you, but this is the easiest and quickest way for getting the information needed. You should be able to copy and paste the terminal output by highlighting it with the mouse and right-clicking -> copy.

    I'm assuming you have an Ubuntu Studio disc already. If not, post back and we'll take it from there.

    Re: Need advice on how to install Ubuntu without erasing everything on my hard drive

    @coffeecat: hi & thank you for the help!

    Ubuntu Studio - the last version of it - does not have a live DVD, but you're right, all my partitions at the moment are formatted in NTFS.

    I assume that if I install Ubuntu S on the current Win partition, that's where my home and root folders will be. Then I'm left with mounting the other two personal partitions (found info here http://www.tuxfiles.org/linuxhelp/mounting.html).

    How can I proceed with the installation? Alternatively, if things get to messy, I could backup everything and format the entire drive. But I would prefer to face this learning curve head on and learn how to fix things/ adapt step by step.

    Thanks again for the help.

    To be honest, even considering myself relatively experienced using linux at home I would chose to back everything up then wipe the disk and start afresh. Then you will be able to use ext4 (which is rock solid) on all your partitions. You'll also be able to design your own partition table. Fr example at the moment I use 3 partitions (well 4 including swap).
    1) My root filesystem - holds the operating system
    2) Home - contains all my personal settings
    3) Media - contains all my media. I like to keep this separate from my home. Then I symlink it to my home folder
    4) Swap

    It would look something like this during the installation:
    sda1 20GB /
    sda2 20GB /home
    sda3 300GB /home/media
    sda4 3GB swap

    Re: Need advice on how to install Ubuntu without erasing everything on my hard drive

    edm1, thanks!

    I'm convinced. Before I dive into this, I still have a few more questions. Can you please tell me:

    - taking your partition arrangement as example, which are the ones that will be automatically formatted when I will do a future clean install?

    - to have a setup like yours, do I choose the option 'manual' during installation (13th image from the top) - https://help.ubuntu.com/community/Ub...resh%20Install

    - and the slightly silly question: if I want to select multiple options during the installation process, is Ctrl + Space the way to do it? (first image under 'Software Selection' section https://help.ubuntu.com/community/Ub...resh%20Install)

    Many thanks!

    1) If you are still planning on backing everything up, wiping everything, then reloading your data you dont even be wanting to format any of them. Just delete all the existing partitions and start afresh.

    2) Yes, chose manual if you would like to set up separate partitions. If you decide you just want 1 partition with everything on then go for use entire disk.

    3) Ive always installed using the desktop live usb and have never used the alternate install method that Ubuntu Studio uses but it looks like you just move down the list and click space to select.

    If you use the "manual" partitioning option (and to answer your question, yes, that is the option you want to use to set up your own partitioning scheme), nothing is done automatically. Only the partitions that you select to be formatted will be formatted. That is the value of a partitioning scheme as edm1 suggested. If the machine falls on it's head, you can just re-install the / partition where the system is and simply re-mount the partitions with your data without formatting them. All your configurations are in the /home/user folder, so when you re-install the applications they come back up just as they were before the re-install.

    Ah, that step is not intuitive at all. If I remember rightly, it is up and down arrows to choose, space bar to select or deselect, and enter to continue. I remember it being somehow not quite the same as the preceding steps. Don't panic, though. If you accidently tell it to go on without having selected them all, you can very easily install the missing bits via Synaptic when the install is finished. There are packages in the repository that correspond exactly to the options in the installer.

    Re: Need advice on how to install Ubuntu without erasing everything on my hard drive

    People, thank you so much for the help and for the super-fast replies!

    It's done, installed and looks excellent!

    For reference sake, here are some links I kept handy while going through the installation:

    http://www.howtoforge.com/the-perfec...u-studio-11.10 - a very detailed guide, with more print screens than the one on Ubuntu Studio wiki

    http://www.linuxbsdos.com/2011/05/04...-ubuntu-11-04/ - might be of some help although the interfaces are quite different

    + the occasional Google to find out about Primary partition and whether I should make the partition at the beginning or end.

    Now I have a first headache with the network manager that is missing and I have no idea how to set up the wireless - works perfect with the cable though. But I'll start another thread for that.

    Cheers to all!

    Re: Need advice on how to install Ubuntu without erasing everything on my hard drive

    Before I let this topic go, I need to shed some light on how I partitioned the drive:

    My intention was to have, as @edm1 suggested:
    sda1 20Gb /
    sda2 50Gb /home
    sda3 86Gb /media {it did not allow me to call it /media, so I chose the default option /usr}
    sda4 4Gb swap

    Now, when I run the df -h command to find out disk space, I get these results:
    Filesystem Size Used Avail Use% Mounted on
    /dev/sda2 19G 1.5G 16G 9% /
    udev 991M 4.0K 991M 1% /dev
    tmpfs 400M 996K 399M 1% /run
    none 5.0M 0 5.0M 0% /run/lock
    none 1000M 732K 999M 1% /run/shm
    /dev/sda3 46G 328M 44G 1% /home
    /dev/sda4 79G 4.0G 71G 6% /usr

    How is this different from what I wanted to achieve?
    Why does /usr has 4Gb occupied? That was suppose to be the partition for my media files.

    Cheers,
    Adrian

    /usr is a system folder. It now is controlled by / (root) and is used by the system. All the defaults on the installer are to allow the creation of different partitions for all system folders. Used by servers not needed on desktops.

    You either needed to partition in advance or as part of the install just leave the space and come back and create then new media partition and mount it manually.
