I am unable to create a liveUSB install of Fedora-15-i386-DVD.iso.
first I tried
dd if=~/Download/F15-Server-i386-DVD.iso of=/dev/sdc
copies the files fine, but will not boot. not sure why? something flashes by too quickly and then boots from the HDD.
/dev/sdc1 has the boot flag set.
As I do not have access to a Fedora system, what other method can I use to create a liveUSB?

Ed, I already mentioned that I do not have access to a Fedora system. Secondly,
Preparing the USB stick
The easiest setup method is to install Fedora's own *livecd-iso-to-diskhttps://fedoraproject.org/wiki/Livecd-iso-to-disk * script from livecd-tools. Note that the liveusb-creator GUI, however, does not support putting the DVD installer on USB. (Unetbootin has worked in the past as well, but does not currently work for Fedora 14 and 15.)

I am curious why the DD command fails?
any guesses.

Then use the Windows version!
It will download what is needed.

I just used DD to make a USB using the LIVE CD iso (not DVD). It works fine. Maybe the DVD version is arranged differently (obviously).

For some related information, you may wish to see this article:
http://mjg59.dreamwidth.org/4957.html
Which goes into a lot more things than the differences between booting from CDROM and booting from USB stick, but it does discuss those differences, and is overall an interesting article on the contortions one must go thru to boot from various different kinds of devices on different hardware and differnet operating systems.
Because of the differences, a vanilla bootable cdrom image won't boot from USB and an image designed to boot from USB won't boot from cdrom. But apparently it IS possible to construct an image that will boot from either kind of device, so that such an image could be written to a USB device via DD and expected to work. But the "standard" way of creating cdrom images doesn't support that.
Hence the need for the various tools floating around for creating bootable USB from a bootable cdrom image.

The Fedora-15-i386-DVD.iso image does not have the hard drive boot loader code at the beginning of the image. So it will not boot when copied to a USB stick. Where the hard drive boot loader and partition table are on a hard drive are all zeros on the DVD images.
The live CDs do have the code, so they will boot when copied to a USB stick.

That's good to know. Any idea how to create a DVD image with the hard drive boot loader code? My google foo came up empty.

Using livecd-iso-to-disk script worked.

Thanks for the info.
This method of putting the DVD iso onto a usbkey I have been using for some years and works consistently. One word of caution though is that when it comes to using the usbkey to do an install to the hard drive of the machine you are installing to, you have to be careful when you reach the bootloader screen. Unless this has been fixed in very recent versions, you will likely find that by default it will attempt to put grub onto the mbr of the usbkey instead of putting it onto the mbr of the HD! So at this point you need to swap over the first and second bios drive in the options on the bootloader page during the install, and make sure that it says that it will put grub onto the mbr of the hard drive. Only then will your newly installed system boot normally once the install is complete. The other thing is that if you do not do that then you may find you can't boot your key either once the install completes since its mbr would have been overwritten.
Other than that this method of install works nicely and saves having to burn a disc. Hopefully at some point the little wrinkle about the bootloader watchpoint when using this method will be resolved so that there is no need to take care of it manually during the install.

I probably should add that this is for the official DVDs. There is no reason that it could not be added.

It is a rough one to fix. The problem is with the BIOS mapping. The USB drive is being assigned the first hard drive ID. (81) But this ID is assigned to the boot drive when you boot from the hard drive. You run into the same problem when you change the drive you boot from in the BIOS, or the BIOS boot menu. Grub uses the BIOS mapping to find stage 1.5 or 2 when booting.
Now, when you boot from a CD/DVD, the mapping is usually the same as when you boot from the first hard drive. This mapping may not be the same as when you boot from the hard drive, depending on the BIOS settings. Some BIOS will let you set the mapping so you can decide what drive comes first regardless of where it is connected. This is especially true with SATA drives.
It is fairly simple when you have one SATA drive, and one USB drive and are installing from the USB drive. Then you just swap the first two entries, as you said. With more then one hard drive, this may not work. You have to know what drive you are set to boot from.
