    Windows 7, Ubuntu 32 Bit, Ubuntu 64 Bit

    Just got this refurbuished machine. 64 bit, 1 TB HD. Pre-loaded with Windows 7.

    I installed 32 bit Ubuntu 12.04 using the recommended disk partioning, for a dual boot setup.

    Then it *finally* dawns on me I just bought a 64 bit machine.

    When I tried to install 64 bit Ubuntu 12.04, it did *not* offer to repartion the drive for me. Just "erase all" and "configure the darn thing yourself" more-or-less.

    Well, I have *no* idea what's what with all that stuff.

    Any ideas?

    Thanks!

    Hi Glkanter,

    Have you tried using (not installing) Ubuntu from the liveCD and partitioning the hard drive with Gparted? You should then be able to select that partition for installation during the 64 bit install process.

    I have not tried that.

    Will Gparted prompt me with a viable partition arrangement?

    Glkanter;
    My memory may be a bit hazy, but does not the installer advise you of what is installed and give you the option to install over one of them ?? Like over the 32 bit install; I can not imagine a reason to keep the 32 bit install.

    GParted: Yes there is both a graphical display of the partitioning scheme as well as in the editor it's self, a textural list. GParted is available from the liveCD, One may look at the disk(s),read the documentation, delete the ubuntu 32 bit install partition(s), re-write the partition table and exit GParted back to the desktop and then click the install icon to install the 64 bit system.

    hope this helps

    The cd installer only offered to erarse the whole thing, or let me configure it. It did not propose any solutions.

    I goofed. I can live with it. I just don't have the experience to monkey around with Linux partions via either the installer or Gparted.

    Thanks guys!

    Hi:

    It did not propose any solutions.
    That's odd--

    You could shrink the Win's 7 parition first before the Ubuntu install-
    Make sure you write those partitions down so that when the Ubuntu partition manager shows you all of the partitions you know which partitions not to bother.

    If it were me I would download the ISO Image of Ubuntu for X86_64bit architecture.
    Put in the new Ubuntu install and when it comes time to partition choose 'manual'
    Delete the 32bit Ubuntu install partition (journaling file system) that you already created.
    Delete the 32bit Ubuntu install swap that you made.

    Now take advantage of that free space from the old partitions that you just deleted and create new partitions.
    -Highlight the free space
    -Create a new partition (make your (/) ext 3 journaling file system 20GB
    -Create another new partition (make your swap space ....2GB
    Done, finish and write to disk--

    As an example here is what I recently did for a dual boot with Win's 7 and Fedora:
    Code:
    dev/sda1* Windows 7 Home premium NTFS
    dev/sda1 Windows 7 Recovery  NTFS
    dev/sda/ 5 / boot ext 3 20GB for Fedora
    dev/sda 6 swap ext3 2GB
    dev/sda 7 home  ext3 2GB
    dev/sda 8 root ext4 2GB
    The only reason I made 2 additional partitions is because the Fedora documentation recommends it-

    Hope this helps-

    Done.

    Yes.
    Delete the 32bit Ubuntu install partition (journaling file system) that you already created.
    I'll copy any of my files onto a usb drive, first.
    Delete the 32bit Ubuntu install swap that you made.
    Yes.

    Now take advantage of that free space from the old partitions that you just deleted and create new partitions.
    -Highlight the free space
    -Create a new partition (make your (/) ext 3 journaling file system 20GB
    I have a 1 TB HD. About 500 GB belongs to Ubuntu, the other 500 GB belongs to Windows.
    -Create another new partition (make your swap space ....2GB
    This will only account for 22 GB of the 500 GB available. Is there an implied step, that I am missing?
    Done, finish and write to disk--
    That would be great...

    I will wait to hear back from you before proceeding. Thanks!

    AFAIK SWAP is not architecture dependent (correct me if I am wrong). Earlier SWAP size used to depend on the architecture but not any more. No need to delete it. If in doubt you can re-format it.

    In fact no need to delete anyting. Just boot you Ubuntu_64 LiveDVD/USB and Install. When you reach the screen where you are offered install on HDD options choose "Something Else" to point the installation to the partition where you installed Ubuntu_32 and just format it using ext4 filesystem. Then continue.

    Make sure Grub is being installed to /dev/sda ONLY and not on partition like, /dev/sda1 or /dev/sda2 and so on.

    As Fantab said: Choose the "Something Else" option in the Ubuntu installer and select your existing Ubuntu partition. Click Edit (I think... or Properties or something like that) and set the mount point to /

    Then click Ok and then Install. It's that easy!

    I'm assuming you didn't set up a separate /home when you first installed Ubuntu - doesn't sound like you did as that would have required using the Something Else option too.
    I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
