USB 2 flash drives are particularly slow when there are many small files to read and write. This makes them 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. Cameron in this link, post 5. See also the following links Link to USB 3. In the beginning of , it seems that there are no really fast pendrives below 16 GB. 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.

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. 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, 4GB, 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 Some pendrives that did not work are shown in this link. This user is not the only one who likes 32GB Sandisk. The flash hardware This link to a post by DuckHook in the Ubuntu Forums describes how a flash drive works, and how it can fail, first getting read-only, then totally 'bricked'.
Look for the tips and warnings! Postrequisites - restore the USB stick 'Postrequisites' - after installation: This works in most cases. Otherwise, see details in this link: You install it into an installed system with sudo apt-get install gparted mkusb mkusb with a GUI and mkusb-nox in text mode have built-in features to wipe the first megabyte, create a new partition table and file system. See the following links https: Kubuntu, Lubuntu Xubuntu have the repository Universe activated automatically.
Inserting the USB drive should auto-mount it. Start usb-creator. It looks like this in It is not necessary to erase the USB flash drive, however it is advisable that you do so. 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 See bug: Some of the bugs are caused by conflicts between different versions of syslinux. These bugs do not affect installing in UEFI mode, where grub2 is used. And with the Ubuntu Startup Creator version 0. The Startup Disk Creator alias usb-creator-gtk looks like this in 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 Mount the FAT32 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 FAT32 partition before unplugging it, otherwise you might corrupt the file system. See this detailed description.
It is using dd under the hood. 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. See this link https: The 'grub-n-iso' method uses grub2 to boot from an iso file, so once you have such a USB pendrive, you can boot most Intel and AMD computers that can run a bit system except very old non-PAE systems, systems with too low RAM, and systems with non-compatible hardware.

The 'grub-n-iso' method can be used to create multi-boot USB pendrives by selecting iso file to boot from in the grub menu. There is space in 'grub-n-iso-n-swap' for a second iso file. You can also start from this link to Pendrivelinux and modify the USB drive to suit what you need: However, the 'grub-n-iso' and 'grub-n-iso-swap' USB boot drives use the standard Lubuntu desktop iso file without any fake-PAE installed, and it can boot almost all computers, that can run bit systems, but it cannot be used for UEFI systems. If you want to boot in UEFI mode and install your Ubuntu flavour alongside Windows, you can use for example the ubuntu The One Button Installer consists of a compressed image of the installer with its operating system and tarballs containing the systems to be installed.
It makes it very easy to install a simple single boot system, dual boot or multiple boot systems in BIOS mode. Nowadays, you should always pick bit unless you know that your computer is too old and cannot support it. All systems should take advantage of bit even if they have smaller amounts of RAM. You could use your browser to download pirated content, just as you could use a BitTorrent client to download pirated Read More. For Windows users, the simplest way is Download it and plug in your USB drive before launching it. Be sure to check Format Drive to avoid any potential formatting issues.
Then click on Create and it will start writing the installation image onto your USB flash drive, essentially turning it into the equivalent of an installation disc. So open the Terminal, then use the following commands:. Begin by switching to the Downloads folder with. Make sure you replace xxxx with the rest of the filename of the downloaded ISO. Follow this with.
UNetbootin (Automated, graphical approach)
This writes the installation ISO onto your flash drive. Click Ignore on the warning box, and then run. This safely ejects the flash drive so that everything is finalized before the system considers it no longer connected. First of all, congrats if you already have Linux on a computer and just need to make an installation flash drive. Then, just do:. This will write the installation ISO onto your flash drive. Finish off with. Congratulations, you now have a USB flash drive you can use to install Ubuntu!
This is usually done by pressing one of the following keys repeatedly as soon as the computer turns on: F2, F5, F6, F8, or F Often but sadly not always , the computer will display which button needs to be pressed before it continues to boot the operating system. That way, it will start the installation media rather than your usual operating system. Think of these as ways of quickly re-installing Windows -- either keeping your personal files or deleting Read More to boot from the USB device.
As soon as you turn it on, hold the Option button for a few seconds until you see a selection screen. Press the right arrow key to move the selection to your flash drive, and then hit Enter to boot the installation media. Installation should be the same as with a DVD from here. If you choose to do manual partitioning, the USB installation media will appear on the list of drives. Just be sure to know which one is your USB drive as it should have a much smaller capacity than your hard drive and make sure not to touch the partitions on it nor have it selected as the installation target for the bootloader.
Ubuntu should now be installed on your system, thanks to your USB flash drive! You can keep it as it is and reuse it to install Ubuntu on other computers, overwrite it with the installation image of another distribution, or even just reformat it to use as a regular flash drives for files you need to carry with you.
