How to Correctly Partition a Hard Drive

I recently got an MSI gaming laptop. It has two drives installed, ssd (c) and hdd (d). The system is installed on ssd. Even though it had pretty good specs it was running slow and laggy. I tried everything, cleaned the disk, closed all unnecessary running processed in the background, put into performance mode it was still slow and laggy. I read in another forum that someone tried to move the system files from ssd to hdd. I used the minitool partition wizard to move the os from ssd to hdd. I was hoping to see the os on my hdd and the ssd clean and empty, but instead I got two more discs G and H. Is it suppose to be like that? It did speed up the laptop though

Cloning just copies, doesn't remove anything from original drive. If you took that screenshot after the clone, then there is still only one OS installed and thats the SSD.

Can you please suggest how to properly move OS from ssd to hdd on the same computer? Maybe there is a previous discussion you can point me to? Thank you.

i dont think moving your os to your hdd is gonna speed the ssd up.now is the time to post specs,including the ssd.

Your SSD may be failing. What is the model of it?

If it's running like crap out of the box I'd see about returning it for a replacement. Moving your installation to the HDD would both slow it down comparatively, but also increase your unbootable-pc risk since hard drives are easy to damage (shock, moving the laptop while on, etc) comparative to solid state drives.

The slowest SSD is still much faster than the fastest HDD. Best to find out why your system is lagging rather than move the OS to the HDD.
