Hello, how are you?
My name is Paloma B., I am very happy to be able to try to help you in the best possible way.
This is an open community, whenever you need you can share the problem so that possible repairs are suggested.
Could you give more information about the problem, please?
Please share a Disk Manager screenshot?
As I understand it, Windows was installed on the HDD, and you bought an SSD and transferred Windows to the SSD.
However you kept the HDD in your computer, so in that case you have two EFI partitions correct?
If so, you can remove it from HDD as it is not being used.
Only the SSD partition is in use if Windows is on it.
