In this case, the device name is /dev/sdb1 . Unmount that device:

# umount /dev/sdb1

(Notice that there is only one n in umount .)

Now copy the boot image to the USB flash drive:

# dd if=diskboot.img of= /dev/sdb1
16384+0 records in
16384+0 records out

Flush the system disk buffers to ensure that the data is written out to the drive before you unplug it:

# sync

The USB flash drive is now ready for booting. Insert the drive into the target system, turn it on, and use the BIOS options to specify that the system is to be booted from the USB drive; the rest of the process will be identical to booting from a CD or DVD.

When you're done using the drive to install Fedora Core, you'll find that it looks like an 8 MB drive, regardless of its actual drive capacity. To restore its full capacity, format it with a FAT32 filesystem:

# mkdosfs /dev/sdb1
mkdosfs 2.10 (22 Sep 2003)

10.3.1.2. Preparing a network installation server

You can use any FTP, HTTP, or NIS server for network installation, but of these three, HTTP is the easiest to set up and has the least overhead.

You'll need the full set of installation files. You can copy the entire contents of the DVD (or each of the five CDs) to a directory shared by your web server:

# mkdir /var/www/fedora
# cp -R /media/discname /var/www/fedora

Replace /media/diskname with the disc mount point (see the output of df ).

Instead of copying the files, you could leave the DVD in your drive (this won't work with CDs, since you need several of them) and create a symbolic link from your web server's document root to the DVD mount point:

# ln -s /media/ disk /var/www/html/fedora

Since the DVD's filesystem does not support file attributesnecessary to assign an SELinux contextyou will have to disable SELinux enforcement for HTTPD before using it to serve files from a DVD.

Alternatively, you can download the files directory to your web server directory. Go to the web page http://fedora.redhat.com/Download/mirrors.html , select an rsync , HTTP, or FTP mirror site for download, and download the entire distribution (all of the files and subdirectories in the os directory for your platform).

The directory layout varies from mirror to mirror. Use a browser to connect to your selected mirror site to confirm the directory names for the following commands. 

On an existing Fedora Core system, you can do this by first creating a directory that is web-accessible:

# mkdir /var/www/fedora

Then fetch all of the files into that directory:

# cd /var/www/fedora
# wget -nH --cut-dirs= 4 -r http://less.cogeco.net/pub/fedora/linux/core/6/

Note that the URL here is taken from the mirror list, but has the Fedora Core release number ( 6 ) added to the end (replace this URL with that of a mirror close to you). The --cut-dirs= 4 option removes four leading directory names ( pub/fedora/linux/core ) from the retrieved files before saving them.

The downloaded tree will include the ISO files. If you'd rather not download them, use the -X option when you run wget :

# cd /var/www/fedora
# wget -nH -X '/*/*/*/*/*/*/iso' --cut-dirs= 4 -r  http://less.cogeco.net/pub/fedora/linux/core/6/

(The indicates that the command continues on the next line; you can leave it out and type everything on one line.)

The downloaded directory indexes will be saved as files starting with index.html ; these can be deleted using the find command:

# find /var/www/fedora -name 'index.html*' -print -exec rm {} ;

The wget command can also be used with FTP sites:
