user48131: I backed up my Bitcoin wallet on a drive for safety. Luck has it that my computer crashed. So now I downloaded Bitcoin Core, but do not how to retrieve my backup. Please help. thanks

user3697: 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)
