If i find the wallet i could recover it with the phrase. But I dont know which wallet I installed (Bitcoin Core...)
If you have a seed phrase, it's not bitcoin core. Bitcoin core doesn't support seed phrase at all.
Most wallets use the BIP39 standard for generating seed phrase. We have also electrum which uses its own algorithm for generating seed phrase and supports importing BIP39 seed phrase as well.
Download electrum from
its official website,
verify your download, create a new wallet and select "Standard wallet" and then "I already have a seed".
Enter your seed phrase and see if it allows you to click on "Next" button. If the next button is grayed out, click on "Options" and select "BIP39". If you see a message saying '"BIP39 (checksum: ok)", click on Next".
