You seem to have a rare rescue CD.
One can get away with mounting a source partition read only.
You can use the dd to copy a read only disk.
Do you have a swap partition?
Some live CDs can be told to use that.
It doesn't matter much if a swap partition
changes while it's being copied.

I think that with the right boot parameters
you can come up with everything mounted read only.
In that case, running dd should be possible and reliable.
