I have a lenovo laptop that I had previously ugraded to a SSD and had windows 10 installed.
I now need the SSD for something else so I used EaseUS TODO cloning utility to clone the current SSD to the stock HDD.

Now when I boot from the stock HDD, I got inaccessible boot device error twice, but when I restarted a bunch of times I didnt get it. But I do get it sometimes.
I also went into the UEFI bios and disabled AHCI mode.

Also one other thing I noticed. When I checked the windows partitioning utiltiy, even though the disk is 1tb, it shows only 250gb(size of the earlier ssd) and show about 650gb unallocated. Also I noticed there are 4 partitions 1000, 250mb and 450mb. Is it possible that because there are more than 4 partitions its a problem?

My problem is that windows is now running extremely slow! Like slower than how the stock HDD used to perform. In task manager the disk gets highlighted red with 100% usage but the processe list show usage of 0-5mb which is weird.
I have a hunch that the Samsung magician or windows 10 has somehow set optimization settings for a SSD and now that I have a cloned HDD it still thinks its and ssd and is bottlenecking.

Anyone had similar problems? Or can suggest any solution for this?

If it were me I would dissconnect the SSD (Temporarily). Next, within Windows 10 installation delete all partitions on the HDD, format, and do a fresh install of windows 10 on it. From there you can pop in your SSD and start to copy other stuff like files etc... from your SSD to your HDD.

It might be tedious, but it will take longer trying to figure out what is wrong. Plus you have a lot of really weird partitions going on there. I would delete them all, and you are left with one fresh blank partition. If you have anything on the HDD you need, that's not on the SSD, then backup first.

I would also not copy programs from the SSD to HDD. I would re-install them fresh as well. Drivers, you should be able to copy, but If it were me I...

You are looking at four hours of your time this way. It's worth it to have a clean, fresh install. By (Temporarily) disconnecting the the SSD or any extra drives, you save yourself from accidentally deleting one of the SSD's/ Other Drives partitions, and are left only with partitions belonging to the HHD. It's worth taking the extra 10 seconds to do that.

Not trying to cause you extra work, but I would not even to begin to fiddle with that. Your best option is to use a usb drive to run documents, movies, music etc... from. This way if you ever do another clean installation, all you need to do is install windows, drivers, and programs.

I only put on the desktop what I am currently working on. All my work files etc...are on other drives, because I am always fresh installing at least once a year if just to be running at 100% as much as possible.

Thanks a lot for the suggestions. I'm just gonna sacrifice my SSD to the mercy of windows and just let it be. haha Since it has been working flawlessly for the past year, I'm not gonna try to migrate to the stock HDD for now.
