Restoring a wallet on a fresh machine:

Start Bitcoin-Core (daemon or Qt), shut it down after it has started up (you only do that to create the necessary data directory)
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)
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 Jul 17 '17 at 00:28
Call it via bitcoin-cli 10000 times (maybe write a script). – Jonas Schnelli Jul 17 '17 at 12:14
Did -rescan option not work for 0.14? It does the job in 0.15. – nopara73 Sep 29 '17 at 13:41
