Just to clarify the following is the file I am copying: wget -c http://mirror.anl.gov/pub/fedora/linux/releases/7/Fedora/x86_64/os/images/diskboot.img And then I use the dd command: dd if=/media/dvd/images/diskboot.img of=/dev/sdb bs=512 but to no avail. Is it possible that I am making a mess somewhere? Is it that bs has to be something else? Note that I do potentially get a bootable USB since it says boot error, rather than OS not found. Can anyone please help? Best wishes. Trotter ____________________________________________________________________________________ Fussy? Opinionated? Impossible to please? Perfect.
