Almost all modern PCs can boot from USB sticks. However, how you tell the system to boot from a USB stick varies substantially from system to system. Initially, you can try this:
Booting from USB sticks
For more information on all this, see the https://fedoraproject.org/wiki/Unified_Extensible_Firmware_Interface[UEFI page]. USB sticks written from x86_64 images with xref:creating-and-using-a-live-installation-image.adoc#using-fedora-media-writer[Fedora Media Writer], xref:creating-and-using-a-live-installation-image.adoc#gnome-disk-utility[GNOME Disk Utility], `dd`, other dd-style utilities should be UEFI native bootable. Sticks written with other utilities may not be UEFI native bootable, and sticks written from i686 images will never be UEFI bootable.
Identifying a stick on Linux
If the computer is configured to automatically boot from the USB drive, you will see a screen that says "Automatic boot in 10 seconds..." with a countdown.
If the computer starts to boot off the hard drive as normal, you'll need to manually configure it to boot off the USB drive. Usually, that should work like this:
If you do a native UEFI boot, where you will see a rather more minimal boot menu.
If your system has a UEFI firmware, it will usually allow you to boot the stick in UEFI native mode or BIOS compatibility mode. If you boot in UEFI native mode and perform a Fedora installation, you will get a UEFI native Fedora installation. If you boot in BIOS compatibility mode and perform a Fedora installation, you will get a BIOS compatibility mode Fedora installation.
Insert the USB stick into a USB port.
Most of the writing methods will require you to know the `/dev` name for your USB stick, e.g. `/dev/sdc`, when using them on Linux. You do not need to know this in order to use Fedora Media Writer. To find this out:
Near the end of the output, you will see something like:
Open a terminal and run `dmesg`.
Plug the USB drive into a USB port.
Power off the computer.
Power on the computer.
Remove all other portable media, such as CDs, DVDs, floppy disks or other USB sticks.
Save the changes, exit, and the computer should boot from the USB drive.
`sdX` will be `sdb`, `sdc`, `sdd`, etc.
This is the name of the disk you will use. We'll call it `sdX` from now on. If you have connected more than one USB stick to the system, be careful that you identify the correct one, often you will see a manufacturer name or capacity in the output which you can use to make sure you identified the correct stick.
