Comment 6 for bug 1325801

i would recommend first checking the md5 of the iso AND the usb against the published md5. if it fails, it is an error in either the download process (iso fails) or the usb creation (usb fails). try a re-download or a re-creation, depending on what's appropriate.

assuming that's no problem, i'd try it out on a different machine (or perhaps a different virtual machine).

failing that, and assuming everyone is using usb-creator-kde, it should be checked against usb-creator-gtk. i doubt there's any difference, but maybe. if that fails, too, then the next step would be to try unetbootin and dd.

if there's a consistent problem on all machines and all methods of creating the usb, i would file the bug against syslinux, since that suggests the issue is with the iso itself. i would do the same if it is specific to a particular machine, although we might want to dig deeper to find out what specifically is the issue (perhaps some driver or something).

if one usb creation method works where others don't, the bug should be filed against the ones that don't work. i have found in general the unetbootin provides pretty good results and dd never fails.

hope that helps!
