i cloned a ssd to a harddrive but windows wont start from the hard drive
Then you did something wrong, or there is a hardware fail.

Redo it, just like this:
-----------------------------
Specific steps for a successful clone operation:
-----------------------------
Verify the actual used space on the current drive is significantly below the size of the new SSD
Download and install Macrium Reflect (or Samsung Data Migration, if a Samsung SSD)
Power off
Disconnect ALL drives except the current C and the new SSD
Power up
Run the Macrium Reflect (or Samsung Data Migration)
Select ALL the partitions on the existing C drive
Click the 'Clone' button
Wait until it is done
When it finishes, power off
Disconnect ALL drives except for the new SSD
This is to allow the system to try to boot from ONLY the SSD
Swap the SATA cables around so that the new drive is connected to the same SATA port as the old drive
Power up, and verify the BIOS boot order
If good, continue the power up

It should boot from the new drive, just like the old drive.
Maybe reboot a time or two, just to make sure.

If it works, and it should, all is good.

Later, reconnect the old drive and wipe all partitions on it.
This will probably require the commandline diskpart function, and the clean command.

Ask questions if anything is unclear.

" i could see on the drive self it had windows and stuff"

At the end of the clone process, do not poke around in the new drive.
The FIRST thing you do is to power off, remove the old drive, and let the system boot up from the new drive.

What are all the drives in this system?

@USAFRet I have a very similar issue- I did all of these steps in your original post to the letter EXCEPT at the very end, I formatted the old drive using the windows disc management program but DID NOT remove the multiple partitions that were on the drive. I reinserted the old drive and now my new cloned drive is unbootable and isnt even being recognized in BIOS. what should I do? I know that I still have all the data on the cloned drive because I hooked it up via sata on a different pc and saw that all the files were still in there but its just not bootable. is there a way to make it bootable again?

heres a link to my help thread if you can please help me: https://forums.tomshardware.com/threads/need-fr-help-with-cloned-ssd-not-showing-up-in-bios.3608081/

To make your computer successfully start from a cloned hard drive, you need to:
  1. Make sure that the partition style of the cloned hard drive is compatible with your PC’s BIOS boot mode. All PCs and laptops boot in one of two ways: the traditional BIOS-MBR method and the newer UEFI-GPT method. Format the new hard drive with the same partition style as the old SSD so that you can’t go wrong.
  2. Make sure that you used a reliable hard drive cloning tool and the cloning process went well.
  3. If you keep both the old SSD and the cloned hard drive in your PC, you need to enter the BIOS screen to select the cloned hard drive as the first boot device.
If necessary, refer to this article: https://www.isumsoft.com/windows-10/how-to-boot-from-ssd-after-cloning.html
