Stable portable systems - good for USB sticks Pendrivelinux's Universal USB Installer Creating a bootable Ubuntu USB flash drive from Windows Creating a bootable Ubuntu USB flash drive from Mac OSX![]() Files on this USB device will be erased, so backup the files you want to keep before making the device bootable. If the iso file is smaller than 2 GB, it is possible to use a 2 GB USB device, at least with some of the methods. Unetbootin, may create slightly different boot drives or if on UEFI might not work at all with Debian iso files due to a bugNote: This article uses the term "USB flash drive" alongside USB stick, USB drive, USB device, USB pendrive and thumb drive.To create a USB installation device, you will need:A 4 GB USB flash device/drive/stick. 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. 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. And a USB 3 SSD flash drive has much faster flash hardware, and there are USB 3 pendrives with specified high read/write performance. 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 eSATA drive. 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. Booting from USB 2 from a live drive is faster than from a corresponding CD/DVD disk. Best drive scheme for video editing on a macIn the beginning of 2017, it seems that there are no really fast pendrives below 16 GB.2 GB is enough for a live USB flash drive made from a 'CD size' iso file. Typically the speed is between 4 and 20 MB/s.USB 2 flash drives work, but USB 3 drives with specified high read/write performance (or even USB 2 HDDs) are recommended for persistent live systems and 'installed systems'. 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.Link to USB 2 and USB 3 speed tests for installersStandard USB 2 flash drives are good for normal live systems. Also the lifetime (number of write operations on a memory cell) is much higher with the high quality hardware in USB 3 flash drives. Some USB pendrives and computers 'do not like each other'. They are made to be mass storage devices, and have not exactly the same electronics and firmware. Some of them cannot be used for booting. And some USB pendrives just have issues also. If you want a fast system, install it into a pendrive that performs well in a test, even if it is 'bigger than necessary'.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. ![]() You install it into an installed system withMkusb 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. This works in most cases.Gparted comes with the iso file but is available only in the live system. The standard is an MSDOS partition table (MBR) and a partition with the FAT32 file system.In order to re-use the stick after installing Ubuntu, just format it completely (including MBR) using gparted in Ubuntu or Disk Management in Windows. in the top pane of usb-creator, pick the. Inserting the USB drive should auto-mount it. Insert and mount the USB drive.
