Trying to install OS, live cd kicks back "invalid or corrupt kernel image", and live usb isn't getting picked up from bios I used xfburn to burn a live dvd, verified before and after and the iso is supposedly fine. Then when that didn't work I used this string to make the live usb:

    dd if=/path/to/os.iso of=/dev/sde bs=4M; sync

but the usb is not getting picked up by the bios.
