I have two independent copies of macOS Catalina installed on two different disk partitions.
Somehow, when I change Spotlight privacy settings in one of them, same settings and up applying into another system after I boot it up.
How is that possible and how can I fix it?
Try to repair the Windows boot sector using the Startup Repair Tool by Microsoft.
You can attempt a Startup Repair using these instructions:
Insert the Windows 7 installation disc or USB flash drive, or a system repair disc, and then shut down your computer.
Restart your computer using the computer's power button.
When prompted, press any key, and then follow the instructions that appear.
On the Install Windows page, or on the System Recovery Options page, choose your language and other preferences, and then click Next.
If you are using the Windows installation disc or USB flash drive, click Repair your computer.
Select the Windows installation you want to repair, and then click Next.
On the System Recovery Options menu, click Startup Repair.
I found this issue when searching for the web. Though it's been some time since the original asker has posted his question, I thought that it would be worth noting that, as of October, the Mac OS X 10.7.5 supplemental update resolved my Spotlight issues.
I was experiencing symptoms similar to the original poster's, with the same error messages that he encountered.

Adding a volume to Spotlight’s Privacy tab adds a ‘no index’ file to the root of the volume. This file will then exist for the other OS to read and be applied.
It’s not possible for one OS to index a volume and another not since the index is stored in a hidden Spotlight folder in the root of the volume, not unique to an OS.
