Restoring my backup image, need help

Can anyone help? This isn't as easy as I thought it would be.

 

My problem is I don't know whether to check the box beside the five partitions in the source field. Why is it there? Just in case I want to uncheck any of the partitions? All partitions are checked, and I definitely want to keep them that way, so should I just leave the box unchecked as it is?

 

OK. Well everything's sorted now anyway. I tried checking the box to see what would happen, couldn't do it. All that happened when I tried was the screen flickered. I tried again and nothing happened. So I went through with finishing the restore (took a lot longer than I thought), but now everything's as it should be. But after the restore was completed, and I went into the BIOS to change the boot priority, I saw that number 1 on the list was now Windows Boot Manager. Is it safe to change number 1 back to the hard drive?
