How do I install Lexar’s JumpDrive Secure on my Mac? Once that finished installing I reran the install script and was unsurprised when Jump Drive Secure installed.
Installation/From. USBStick - Community Help Wiki. Outline. The general procedure to install Ubuntu (or Ubuntu flavour, Kubuntu, Lubuntu, Xubuntu, ..) from a USB flash drive is: Acquire the correct Ubuntu installation files ('the ISO') Put Ubuntu onto your USB flash drive Configure your computer to boot from USB flash drive and boot from it Try Ubuntu (Kubuntu, Lubuntu, Xubuntu, ..) before installing it. Install Ubuntu to your internal drive (hard disk drive or solid state drive). Introduction. Ubuntu can be installed from a USB flash drive. This may be necessary for netbooks and other computers without CD drives and is handy for others because a USB flash drive is so convenient. Also, you can configure Ubuntu on the USB flash drive to save changes you make, unlike a read- only CD- ROM drive.
Booting from a USB flash drive created with usb- creator alias Startup Disk Creator and mkusb will behave just as if you had booted from the install CD. It will show the language selection and then the install menu, from which you can install Ubuntu onto the computer's hard drive or launch the Live. CD environment. Other utilities, e. Unetbootin, may create slightly different boot drives or if on UEFI might not work at all with Debian iso files due to a bug.

Note: This article uses the term "USB flash drive" alongside USB stick, USB drive, USB device, USB pendrive and thumb drive. Prerequisites. To create a USB installation device, you will need: a 2 GB USB flash device/drive/stick. If the iso file is smaller than 1 GB, it is possible to use a 1 GB USB device, at least with some of the methods. Files on this USB device will be erased, so backup the files you want to keep before making the device bootable. Make sure this USB device is properly formatted and mounted.
Ubuntu flavour ISO file (see Getting. Ubuntu to download it) Notes about speed. The most common USB ports and USB flash drives work according to the USB 2 standard.
Booting from USB 2 from a live drive is faster than from a corresponding CD/DVD disk. Standard USB 2 flash drives have rather slow flash hardware, with read and write speed much slower than the transfer speed of USB 2, so it is worth checking if the speed is specified.
USB 1. 1 is also possible to use, but it is very slow, slower than a corresponding CD/DVD disk. Hardware according to the USB 3 standard is much faster than USB 2. So if you have a USB 3 port and a USB 3 flash drive, booting and running will be as fast as from an internal drive (SATA or IDE) or an external e.

SATA drive. And a USB 3 flash drive has much faster flash hardware, and it is usually specified. The market changes quickly, so it is worth checking on the internet, which brand and model to select to get the best buy 'today'. USB 3 flash drives are much faster than USB 2 flash drives also in USB 2 ports, because the flash hardware is not limiting the transfer speed. For the same reason a USB connected HDD is also much faster than a USB 2 flash drive. USB 2 flash drives are particularly slow when there are many small files to read and write. This makes then very slow when running persistent live systems and 'installed systems' (installed in the normal way, but to a USB drive).
Also the lifetime (number of write operations on a memory cell) is much higher with the high quality hardware in USB 3 flash drives. But still, you should use noatime in fstab and use swap only for extreme situations to avoid excessive wear.
A LED (light emitting diode) helps you avoid unplugging the USB flash drive too early (while it is saving data from the buffers in RAM), and decreases the risk of corrupting the file system. Flash drive tests are described by C. S. Cameron in this link, post #5. See also the following links Link to USB 3. Flash Drive Speed Tests.
Link to USB 2 and USB 3 speed tests for installers. Conclusion. Standard USB 2 flash drives are good for normal live systems. Typically the speed is between 4 and 2.

MB/s. USB 2 flash drives work, but USB 3 drives (or USB 2 HDDs) are recommended for persistent live systems and 'installed systems'. In the beginning of 2. GB. Notes about size. GB is enough for a live USB flash drive made from a 'CD size' iso file. But unless you already have a 1 GB drive, you are recommended to get one with at least 2 GB, hence the general recommendation above. GB is enough for 'CD size' iso files as well as many but not all 'DVD size' iso files.
If you want a persistent live system with a decent size casper- rw storage, you need at least 4 GB (2 GB is possible, but might soon run out of space). If you want an installed system you need at least 8 GB (4 GB is possible with Lubuntu, but might soon run out of space). In the beginning of 2. GB. If you want a fast system, install it into a pendrive that performs well in a test, even if it is 'bigger than necessary'. Notes about bootability. Most but not all USB pendrives are reliable for booting, even many of the slower ones, and they are much cheaper, and should be OK particularly for regular read- only live drives (without persistence). Some computer hardware and some operating systems have issues with certain ports.
And some USB pendrives just have issues also. Some of them cannot be used for booting. They are made to be mass storage devices, and have not exactly the same electronics and firmware. Some USB pendrives and computers 'do not like each other'. The pendrive might boot another computer, and the computer might boot from another pendrive (everything else being the same). This is a link to test by Pendrivelinux including bootablility of USB flash drives.
This test was made a few years ago. The cheap and slow Sandisk Cruzer Blade, 4. GB, can be added to the list of reliable pendrives for booting. I have used it extensively for years and it has failed only once (chainloading from Plop in a very old computer). This link shows a bootability test in January 2. Some pendrives that did not work are shown in this link. This user is not the only one who likes 3.

Creating a bootable Ubuntu USB flash drive from Ubuntu. Install and run Startup Disk Creator alias usb- creator. You can find usb- creator- gtk in the Unity Dash by typing "Startup Disk Creator" (Ubuntu Desktop) or usb- creator- kde in K- Menu- -> Applications- -> System- -> Startup Disk Creator (Kubuntu). If it is not there, then you can install it using the Synaptic Package Manager or Ubuntu Software Center.
Insert and mount the USB drive. Inserting the USB drive should auto- mount it. Start usb- creator.
It looks like this in 1. Other" to locate and select the . Alternately, if you have a CD or DVD- ROM with the Ubuntu version you want to install on the USB flash drive, insert it in your CD- ROM drive and usb- creator can use that. It is not necessary to erase the USB flash drive, however it is advisable that you do so. Select the first bootable partition on the USB device as the disk to use The bootable partition should be formatted as either a FAT1. FAT3. 2 filesystem. This is the default for most USB flash drives.
Notes. NEVER use one of your hard drive partitions in this process unless you really know what you are doing, as data will get erased. There may be a bug during the formatting which will cause two partitions to appear when booting from the USB flash drive. Try selecting each of them and one should work. If not, restart the computer and try booting from the USB flash drive again. Creating an Ubuntu 1.
USB stick currently requires that it be made from 1. See bug: https: //bugs.
If you get a DBus error with usb- creator, this bug report may be helpful: https: //bugs. The Startup Disk Creator alias usb- creator- gtk looks like this in Xenial Xerus, a new simplified and much more robust version: This new version clones the iso file, which means that you need neither erase nor format the target drive. It will be completely overwritten anyway by the cloning process. Unetbootin. Unetbootin works well in Ubuntu, when installed via the developer's ppa. The version in the Ubuntu repositories is not up to date in order to install from the versions 1.
LTS and 1. 4. 0. 4 LTS to 1. If you're using UEFI, do not currently use Unetbootin with Debian iso files due to a bug. Start Unetbootin, select an ISO file or a distribution to download, select a target drive (USB drive or Hard Disk), select persistence if you wish, then reboot once done. If your USB drive doesn't show up, reformat it as FAT3. Mount the FAT3. 2 partition (for example by un- plugging and re- plugging the drive). If you don't reboot, because you want to use the pendrive in another computer, unmount (eject) the FAT3. See this detailed description.
USB device safely. Simple, safe, high success rate.
The mkusb tool was developed to make it simpler and safer to create boot drives with the method to flash or clone an iso image or a compressed image file. It is using dd under the hood. The target is a mass storage device, often but not always a USB drive, sometimes an internal drive or an e. SATA drive. Cloning an iso file to a mass storage device makes a boot drive, provided it is a hybrid iso file, post- processed with isohybrid. Most modern linux distros provide hybrid iso files, and you should not treat the file twice. See man isohybrid. This method with dd has a high success rate.
This is the situation now with the new current Ubuntu versions] mkusb is particularly good for pre- release testing and new releases, when the standard tools might not be ready (if the configuration of the booting has been changed since the previous release).
