This could be caused by any number of reasons. How much RAM in your system? How much free space is on your boot drive? Typically during initial bootup Windows has quite a bit of housekeeping so sometimes until this "housekeeping" is completed after bootup some systems will see some slugishness.
I'd be curious what the new Cloned partition(s) look like. Cloning a smaller (160gb) partition to a larger 500 GB drive can be done incorrectly and you'd end up with a Cloned 160 gb partition on a 500 gb drive with unused space be underutilized.
