bootable USB-live - 0+0 records in?

  • 772

Why am I not able to make an USB-live?

I am trying to make a bootable USB-live from http://www.memtest86.com/download.htm

This is what I do on my terminal:

$ lsblk
$ cd ~/Downloads
$ sudo dd if=memtest86-usb.img of=/dev/sda bs=1M;sudo sync;sudo eject /dev/sda

But what I get is:

0+0 records in
0+0 records out
0 bytes copied, 0.000149567 s, 0.0 kB/s

Any ideas?

  1. I think your .img file is empty (or there's something wrong with it), that's exactly what dd says when you tell it to read an empty file:

    $ touch empty
$ dd if=empty of=e2
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000555823 s, 0.0 kB/s

    The Ubuntu live ISO's should have a copy of memtest, under the "Test memory" entry in their menu, similar to this image (at least the used to, haven't booted a "raw" live iso in a while):
