    You don't, you create no more than 3 primary partitions and one extended partition which can contain a lot of logical partitions:

    I have one primary partition for Maverik's / partition (Mav controls grub), everything else is in a big extended partition and they are all logical partitions.

    Re: Installing Ubuntu 11.04 onto an external HDD and make it boot off it

    Sorry guys, did not work at all. Used a fresh CDimage from the link provided (build 26-04-2011, 1PM)
    (1) I placed the bootloader on /dev/sdb but did want to boot--blinking cursor only
    (2) I then reinstalled, this time placing the bootloader on /dev/sdb5 (this is the / directory of Ubuntu install; sdb6 is swap)--still no luck with booting; only blinking cursor
    My machine is a Dell Vostro 3700 with Nvidia Geforce graphics card (discrete)--could this be the problem??
    Do I have to tell Ubuntu where the MBR on the external USB HDD is? because this drive has never been in a Windows machine before? Do I have to install Windows on it first?

    Ok, now I am getting edgy...

    It seems that your model may not work on Linux because of the hybrid graphic card.

    I have a dual HDD external enclosure with 2 320Gb WD HDDs in it. You can have an awful lot of OS' on there. I never had more than 21.

    Not using it now as my interest in Ubuntu is about shot but it is a handy deal for testing. You can have several nearly identical installs and test just one variable per OS. Great if using pre-release programs on pre-release OS'.

    Ran with that on all the time for 3 testing cycles using one of 2 "pure" installs (one funny add ones) as my main OS running boinc full blast (cpu as 99-100% all the time. Rarely booted to my internals at all.

    Boinc is a great way to put stress on an OS. If it will continue to work and do what you want to do while doing that heavy duty number crunching you have a pretty stable OS. I kept 2 OS' for my main so that I could be sure that 1 always worked.

    The other installs were for, besides programs or features from ppas, Lubuntu and Xubuntu. If you have the space you can find reasons for having a lot of installs for testing.

    Or, and I am not recommending this, you can just format your whole drive as one extended partition. All mine are that way.

    You can ruin a drive, or in my case 3, very easily doing this until you;
    a>get the process right
    b>come to your senses and just partition like normal folks

    I stick with "a". I like the extreme flexibility it gives me.

    You do have your bios to boot from the usb devicce first? I would double check that.

    If you do, and the bugger just won't do it, run the boot info script from the live CD and send the results.

    It is a graphic card problem. See my link.

    BIOS is setup to boot from USB external drive (F12 Boot Options).

    I will try the bootinfoscript--do you know how to run this script (execute) the commends in the script? In LiveCD mode, where do I save the script file? and How do I run this script?

    Thanks
