Restoring a wallet on a fresh machine:

  1. Start Bitcoin-Core (daemon or Qt), shut it down after it has started up (you only do that to create the necessary data directory)
  2. Replace wallet.dat with your backed-up wallet.dat (see https://en.bitcoin.it/wiki/Data_directory if you can't find the data dir)
  3. Startup Bitcoin-Core, wait until your node is in sync (can take a couple of hours/days)

If you have created the wallet with Bitcoin-Core >= 0.14 (HD Wallet).

2a. Startup Bitcoin-Core (Qt/core), call getnewaddress 100-10000 times (depending on how many addresses you have created) (This hopefully will go away in Core 0.15)

What does it mean: "call getnewaddress 100-10000 times"? How to do it on windows? – JavaRunner – 2017-07-17T00:28:24.767

Call it via bitcoin-cli 10000 times (maybe write a script). – Jonas Schnelli – 2017-07-17T12:14:00.823

Did -rescan option not work for 0.14? It does the job in 0.15. – nopara73 – 2017-09-29T13:41:04.157
