If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
It's likely your computer has went to sleep or into screen saver while your clone was not yet complete.
Most systems moving or clicking the mouse, or pressing a key on the keyboard should wake it up, but maybe on your particular machine this doesn't work.
Is your machine recent hardware? Rescuezilla v2.4.2 is based on a pretty old Linux kernel, but the recent "rolling release" has a newer Linux kernel with better support for recent hardware.
Ability to manage power settings from Rescuezilla itself is an old feature request. One workaround may be to disable power management in the Linux boot menu item.
I've copied my answer from here and posted it below for convenience:
Rescuezilla doesn't yet have any settings application to configure power management settings, because I found all the existing ones adds hundreds of megabytes to the ISO image. If I find a lightweight version I will include it.
I believe a workaround is to boot Rescuezilla, select your language from the boot menu, then highlight your boot item (usually the top item "Rescuezilla"), then press e. Use your keyboard to navigate to quiet splash fastboot and edit it to read quiet acpi=off apm=off splash fastboot. Then press CTRL-x to boot Rescuezilla with these kernel boot options.
Basically those two commands tell the Linux kernel to disable ACPI (Advanced Configuration and Power Interface) and APM (Advanced Power Management). These are the interfaces that the operating system (whether Linux or Windows) use to suspend the system. Please note: disabling ACPI means that when you shutdown the computer will show you a "Now Safe To Turn Off" screen because it's not able to turn off the power itself.
This workaround is certainly not great, but it should work. You may even be able to get away with just disabling APM, I'm not sure.
For my own reference, here are the GitHub tasks covering this issue that I will implement if I continue to be unable to find a lightweight graphical settings application:
