Is the datadir correct? If you go to Help > Debug Window, it will tell you what your datadir is. If it is not correct, go to the folder where Bitcoin Core is installed and find the bitcoin-qt.exe file. Then open a command prompt window. Then type
bitcoin-qt.exe -choosedatadir
and hit enter. This will start Bitcoin Core with the prompt to choose your datadir and choose wherever you want Bitcoin Core's data to be stored. You can then stop Bitcoin Core and start it normally, it will use the datadir you selected.
Also, you will need to reindex the blockchain. This is because you only copied the blocks folder and not the chainstate. The chainstate folder contains all of the databases, and without it, the databases will need to be rebuilt. The reindexing process looks like it is resyncing, but it really is not. It only looks like it is resyncing because it has to read through all of the blocks and validate all of them.
