hello everybody,
before you come to write this post I checked the official documentation of fedora. to be brief:
- I format my usb pendrive in fat - Using the command dd if = fedora-Live.iso of = / dev / sdx (with or without bs for the purposes of issue, and 'indifferent)
Restart the system and remains in the screen with the cursor flashing (infinity) I also tried with other distributions and every time I get the same result side bios and there 'no setting for secure boot or similar
can you give me a hand please? thanks in advance
best regards

Anyone know why there are so many complicated ways listed? Does the obvious dd not work for some people? I've been doing the following for my clean installs for ages. As far as I know that live iso's are structured in a way that they can be used as both a disk image with embedded partition table and a straight iso.
dd if=Fedora-Live-Desktop-x86_64-20-XX.iso of=/dev/sde bs=1M

They're all a little different, for different use cases. Two are CLI, one is GUI. The GUI one runs on Fedora and Windows.
Of the two CLI, one works out of box on most linux, BSD and OS X, or should. It's also destructive, using the whole USB stick.
And then livecd-iso-to-disk is part of livecd-tools which has a pile of features like overlay, encrypted home, ability to install to an existing partition/volume without destroying other partitions/volumes.

That looks like it wipes out any data on the USB Stick, Using Live Creator, if you have free space, it just adds to the USB.

The LiveUSB creator lets you
1) add to an existing FAT filesystem without losing what's already there
2) create a persistent store so changes you make on the live system will be there next time you boot. (But I've had some live USBs stop working, perhaps due to this.)
What it won't let you do is create a Live USB out of an installation .iso. It will silently build the USB but the USB won't work. It would be nice if the Live USB creator refused to attempt this.
dd ought to be faster.

I've found that the dd will be considerably faster if you add oflag=direct

A persistent overlay is used to do this, but it isn't re-writeable: it accumulates changes. Once you run out of space to record any more then things go wrong. (There's an option in the command line tool, but not LiveUSB, to add a home filesystem which is a normal loopback mount.)
An issue I recently encountered: USB created with dd or LiveUSB creator might not boot on EFI systems. The only tool that worked for me was livecd-iso-to-disk with --efi option (required me to add --format, too, so it is destructive).

That bug with Live USB Creator should be fixed. https://bugzilla.redhat.com/show_bug.cgi?id=810112
There might be a bug related to the ISO image, which contains a really unit partition map structure to enable it to boot both BIOS and UEFI systems, whether the media is 512 byte (USB sticks) or 2048 byte (DVDs) physical sectors. To any partition tool it will appear to be corrupt. It's not, it's just unique to fit this purpose. But this has been quite heavily tested over the past 18-24 months so I more likely suspect a firmware bug. But there can also be other boot related issues now that Secure Boot is supported so it's important to file bugs and be really clear about what *does* happen rather than saying it "doesn't boot" which isn't descriptive enough.
The only tool that worked for me was livecd-iso-to-disk with --efi option (required me to add --format, too, so it is destructive).
I vaguely recall some unexpected behavior with --format or maybe the combination of --format with --reset-mbr. But there is some weirdness with LITD in that the --efi option *adds* EFI boot support to a tool that creates BIOS bootable media. So you actually are not getting exclusively EFI boot media, but rather hybrid boot media. Therefore the --reset-mbr is required if the first 440 bytes of LBA0 do not contain BIOS boot code. This is confusing for those who know that such code is ignored on EFI systems.
Anyway, my expectation is if I specify /dev/sdb2 for installation, and use --format --efi --reset-mbr that all other partitions are preserved, but I'm pretty sure that combination blows away the whole partition map and all content on the stick. But it does warn of this also and enables a safe exit via control-C. To me, --format implies using mkfs.vfat -F32 on the specified partition, but that doesn't appear to be the only thing it does.

I thought the LiveCD had the appropriate UEFI stuff already, I have booted the CD on UEFI machines, so I didn't have to think about it. So far all the machines I use have worked with the dd to USB, although that doesn't give you persistent storage.
Been playing with fc20beta3 Live in just that way.
Don't forget untbootin as well, another tool to build USB.
