Can't access network and source file is missing

Hello. I have made backup and when tried booting from Comodo boot CD, network error following message:

Here’s what I see:

Then my only way was to directly restore from partition but I have got another error message about missing source file:

But backup itself is on drive G:

What is the solution? Thanks.
