    Upgrade to 64bit?

    After reading some forums I am planning and thinking of upgrading my Karmic 32bit to Karmic 64bit.


    I have an Asus Eee Pc 1201N which has a 1.6GHz Intel Atom Dual Core 330 Processor & 4GB of Ram

    I currently have my /home on a separate partition
    so if I was to install 64bit what files would I lose any files? As I would only be formating the root partition? Or do I have to format my /home partition?

    Should work fine by formatting / and not /home.

    Great! However what kind of like configs/settings would I be losing? Since I'll be formatting /etc & /bin & /lib... etc..
    I personally don't know what exactly goes in those folders

    I would however of course need to reinstall all my programs correct?

    If you have your /home on a separate partition, then all your personal documents, music, photos and such should be saved. Ubuntu also saves all of your program configuration settings to your /home folder. These folders are just hidden. Go into your /home folder and hit ctrl+h and it will show them.

    When you install the new 64 bit version, given that you don't overwrite your /home partition, all those folders that were in it before will remain there. However, you will need to reinstall the programs/packages that you used in your Ubuntu distro as these will not transfer over when you reinstall. I usually just make a text document and write down everything that I want to reinstall and just save it to /Documents.

    As always, BACKUP your /home before making changes. Things do go wrong every now and then.

    Anything in your home directory like music files would be untouched. Some application preferences like Firefox are stored in the home directory, but not all. Everything else will be lost including installed packages and software. Cheers!

    Are you sure Atoms support 64-bit. Get a live CD or live Flash to test it first. Intel web-page says 64-bit instruction set, but I am not sure if this is equivalent to EMT64 (which is required for 64-bit OS on Intel CPU).

    The only thing that you will need to format is /, if /home is on separate partition, it should be safe. However, there is always a chance that something can go wrong, so it will be best if you backup all of your data first.

    Yeah I'm not quite sure but I'll definately test via live cd tonight. I'm at work right now.

    Thanks for all the input everyone! I'll make a final post on how it all went

    Just make sure when you start telling it where to install / and /home, that you tell it to make /home the partition that your current /home is on.

    Output of "cat /proc/cpuinfo"

    Does this mean I can run 64bit?

    Yes that is a 64 bit processor.
    There are two mistakes one can make along the road to truth...not going all the way, and not starting.
