How to restore register when you can't boot.

CCleaner for Windows

I cleaned my registry and now I can't boot, how do I restore the backup copy? I have a second hard drive in the computer that I can boot to. What's the point of a backup registry if you can't restore it?

Hi hendu, and welcome to Piriform.

Can you boot as far as being able to get into Safe Mode?

If so, you could merge the backup into the registry, or maybe do a System Restore, or maybe "Last Known Good Configuration".

Alternatively, if you can boot to your other hard drive, and I'm assuming it contains another Operating System, can you access and navigate to the backup on your problem drive?
