You can clone with Macrium.
Then use the BIOS Boot menu key to trigger booting the secondary hard drive, after setting the primary first to boot in BIOS.
If this is not satisfactory you can install EasyBCD to the primary to add the secondary on the Add OS tab to create a Windows Boot Menu.
You can use SyncToy to sync the data folders on both drives, in either or both directions, even archive changes.
There is no way to sync programs and settings changes. Easy Transfer will transfer files and settings from old to new drives but settings are a corruption path so I recommend never importing them to a pristine install, or at all.
