Error clone microsd Raspbian

[basicline]

Hi everyone, I'm trying to clone a micro sd with Raspbian already installed and configured by me. What I want to do is back up.
I take the Win32DiskImager and record a file "Copia.img" with the option "Read" program and write in the new microsd with the option "Write" and all right, but when I put in my Raspberry Pi 2 B gives me a kernel panic.
I bought another microsd and the same, also probe the usbit and the same kernel panic. Create a new image with the usbit and clone in the two new microsd and the same.
I have also tried to back with "dd" from linux
The message I get is: no init found working
We will have to change something in the config.txt or cmdline.txt ????
It may have something to do with the internal serial sd ????
In the microsd's if clone an image of clean raspberian tear smoothly.
If I stick with my original boot configurations performed smoothly.
Any suggestions are welcome.
Thanks and regards.

When you use DiskImager's read mode is it copying the whole card, not just a drive? What size is the file it produces?

7.32 GB the size of my microsd
I upgrade "wheezy" a "jessie" for what it's worth. I'm desperate.
You can start by uuid or guid from the cmdline.txt ???

I work anymore, I reinstalled the whole system and reconfigure another microsd and smoothly. The clone with the system itself dd if = / dev / mmcblk0 of = / dev / sdd bs = 4M
Something must have happened in the first installation it worked but kept clone, jjjj
A greeting.
