    Install them on separate partitions and boot into the one you want to use. You should be using 64bit on that machine but understand why you're not.

    I would free up some space, 15Gb say, and install the 64bit there. If you have a separate /home partition it can use that and the existing /swap (although that doesn't really matter in the case of /swap as there's no vital info stored there).

    Just choose 'Something Else' at the partitioning section of the install and tell it to use those partitions but make sure they are NOT ticked to format.

    No, because you don't compare speed between different machines; performance comparisons are only valid for the same machine. You can compare performance improvements between machines, though, and you should see roughly the same ratio of improvement on both machines.

    The trouble with virtualizing is that it may not be running on the same number of physical cores as virtual cores, which introduces too many variables for accurate comparison.

    Mr. Ball, that's good to hear.

    Is it possible to repartition my drive without erasing everything? If so, could you kindly point me toward a howto?

    Many thanks,

    Re: 10.04: Upgrade to Wider Version?

    Yes, it is. You can boot from a LiveCD so all partitions are unmounted, launch Gparted and away you go.

    If you have Windows installed and want to resize that partition, use the Win apps to do that and not Gparted. It can create problems on newer Win versions.

    Do you have free space on your hard drive?

    1) If yes, then you can either add the 64-bit or partition it without wiping out what you have already installed.

    2) If no, then you will wipe out what you have on your computer.

    Thank you, Mr. Ball; I shall investigate in the morning and report back. (I'll leave this thread "unsolved" until then.)

    As for space, it's a 1 TB drive, and Nautilus reports 853.5 GB free.

    Before adding the 64-bit, back up your what is currently on the hard drive. There are no 100% guarantees that all will go right.

    Well that should just go without saying. (Even though it rarely does... )

    Re: 10.04: Upgrade to Wider Version?

    I eventually realized that all the machines I'm likely to use this system on are 64-bit, and since I hadn't really done much with it yet (ie. few app installs, few user files) I'm in the process (as I type this) of wiping the 32-bit install and replacing it with the 64-bit version. (It just took a while to surmount the emotional hurdle of completely discarding the previous install.)

    It would have been interesting to set up the 32/64 dual boot, but I have other stuff needs doing right now, so I'm just going to mark this thread solved.

    Good work. Enjoy. If your machine is capable of the 64bit install, do it.
