Thanks a lot for the issue. Afaik, not all warnings are harmful, but nevertheless I'll take a look. For now, as long as you're getting a "Readahead X maps" message in your logs, you're doing fine.

# increase the verbosity to max
sudo preload-rs -vvv -s state.db

1. Do you mind running the above command, and check if the correct files are being preloaded?
2. If you're running on nvme or SSD, you don't actually need preload. SSDs are already fast enough, so preloading won't do much. Let me know if that's the case.

I have Linux installed as a second OS on the hdd

@1vanK has your problem been solved? Let me know if you're still facing problems.

Btw you can always change configuration to include which directories you wish to preload.
