    32 bit to 64 bit

    I put a thread up a while about about my computer being 32 bit but this is a different question. I wanted to update my computer with 12.10 64 bit but I have no idea if I do it if I will lose my files (pictures, music, etc.). Will I? If so how do I do this to keep my files?

    Re: 32 bit to 64 bit

    Hi!
    I'd suggest to back up your home directory (do not forget the hidden directories) to some external media (USB hard disk, DVD, whatever). This will back up the files and also your preferences which are usually stored in hidden text files in the home dir. After reinstalling the system, all you have to do is copy the saved data back to the home dir.
    If your home directory is on a separate partition, the things are even simpler. Then you'll have to choose that partition for use as /home at installation and do not format it. All files will be totally safe (although backing up is never a bad idea).
    You'll probably have to install the program you use once again after reinstallation.

    Okay, how do I find out if my /home directory is on a separate partition or not? Also I have a dual boot system, will any of this affect the windows side? (a friend of mine set all this up for me because I wanted to learn so I am still learning).

    If your processor is 32-bit, 64-bit won't install.
    Code:
    cat /proc/cpuinfo
    will let us know if its 32- or 64-bit.

    Backup any files you want to save first.

    Please copy result of
    Code:
    sudo fdisk -l
    Also, if you use something like disks or gparted app these will give you an idea.

    my computer is definitely 64 bit. I have a dual boot with windows 64 bit on the other side. For some reason my friend put 32 for ubuntu.

    I would have done the same thing a couple of years ago, due to my doubts about 64 bit's compatibility and stability. But now I've grown smarter

    As you may figure out yourself, you have only one linux partition, the other one is swap partition. Means no separate /home.

    Just boot off the live cd, and copy the /home/<your id> directory onto an external media, done!

    Feel free to ask questions, starting threads in relevant sections, whenever you need help with Ubuntu.

    Hope you'd enjoy the OS and the community here too !
