Strange usage of migrated disk

Hi,

I have laptop with 1TB Toshiba HDD, where was system and data partition. I was cloned system partition to SSD and now system is running from C:

Old system disk have now letter J:

Strange is, that Windows still using some folders on old system partition. I can´t delete some files from old system partition.
But system paths and all programs are set to working from c: (new ssd system partition)

When I try delete some folders from J: then system repair is need at laptop start

Is possible that boot manager is still located on old system drive ? Or how can I investigate, why some files still are created on old system disk?

Hello

OK, but I need have this disk in my computer. Must I delete or format previous system partition?

Note: Old system disk is no marked as system in disk manager

You shouldn't keep two disks configured as system disks in your PC. This tends to confuse upgrades for example, and may result in them failing. When you cloned the system disk, you should immediately have used only the one you intended to use.
When you have removed the drive you don't want, and find the system will not boot, there are plenty of threads you can use as examples if you search the forum for e.g.

I was deleted all previous old system partitions and expanded data partition on whole disk. System working now fine

Your problem seems to be to try to get your PC booting from the cloned disk. To try to fix this problem you will need to remove the other one.
