    Question USB KEY LIVE INSTALL questions.

    I plan on installing ubuntu 12.04 on a usb key for the sake of having an operating system at my finger tips but I was wondering if I could install programs on the live usb key of ubuntu like Skype and a torrent program and various Google programs if supported if so is there anything I need to do or any advice for a better path to take? It'll be on a 32gig usb key so space isn't a huge issue. If I don't respond here please private message me so I get an email to check back here thanks.

    Hello faze1337 ,

    Welcome to the UbuntuForums !!

    You can go for two options .

    1. Make a live Ubuntu usb with persistence .That would remember all your data , configurations and installed packages on next boot .

    2.Go for a normal dedicated installation as you have a good amount of space on your flash drive .

    With 32 gigs I would do a full install.

    The ISO load with a persistent is really designed for short use, it has its own set of problems not associated with a full install.

    Updates are one, you don't want any kernel updates, the ISO is still being used as a read only.

    The persistent file can fill up, and can't be cleaned really.

    A full install will run like a install on a internal drive, although a little slower. Although I had one this way for awhile it was as fast as the internal on a netbook basically. I suspect it depends on the quality of the usb stick.

    How would I go about that plug the key in and reboot choosing the key as the partition? (its been years since I've done this stuff sorry)

    Boot a live cd plug the stick in, and use a custom install, format it there to a ext 4 set the mount as / and install. Make sure in the custom that grub is pointed at the mbr of the stick.

    It would be a normal ubuntu installation , but make sure that you choose the correct device (your 32 gb flash) and not messing up your internal hdd .

    From the live cd environment you can launch gparted and create the necessary partitions as suggested by wilee-nilee above , before going ahead with the installation .

    The rest of the journey would be a normal Ubuntu install .

    Re: USB KEY LIVE INSTALL questions.

    If you want a long term solution, a full install is the best, as explained by previous posts.

    1. If you want full portability, you should avoid proprietary drivers (for example the drivers for graphics and wifi).

    2. A draw-back is that updating is much slower than on an internal hard drive. I think it is because a large number of small files are written, and this is very inefficient on USB pendrives compared to internal drives. So I have an internal drive, that I use at home, and that I can easily clone to and from the pendrive. And I do big updating jobs on the internal drive (it is much faster also taking into account the cloning). This also works as a backup system.

    3. In order to avoid corrupting the file system, you should have a USB pen-drive with a light emitting diode. Then you can see when it is working and you can avoid pulling it out or switching off the computer too early.

    I have such a system (Lubuntu with xubuntu-desktop added) and it works fine. Often the read/write speed is slower than the limits of USB 2.0, so choose a pendrive with high speed. I use a USB 3 pendrive booted from a USB 2.0 port.
