copy the IMG to the USB device and make it bootable

hi

I've done an image according to:

http://www.pendrivelinux.com/create-...-distribution/

then I've copied it using:

Code:

 
# fdisk -l

Disk /dev/hda: 81.9 GB, 81964302336 bytes

575488+0 records out
294649856 bytes (295 MB) copied, 42.2472 s, 7.0 MB/s

but cannot boot from this USB stick.
"First boot device" in BIOS is USB.
What's wrong?

Not sure if what you posted is a typo but you need to copy the image to the device and not the partition. i.e.
dd if=binary.img of=/dev/sda

Thx a lot, using:

Code:

dd if=binary.img of=/dev/sda

works well.
