Attempted and importing was unsuccessful. Just shows Zero balance in the qt. A wallet.dat file appeared in the directory on start up.

I'm going to assume you have already installed bitcoin-qt and that there is an existing wallet.dat in the bitcoin data directory.

1) Make sure bitcoin-qt is not running. (You can check using System Moniter)
2) Go to the bitcoin data directory (it's installed in the home directory by default - if you can't find it this link should help https://en.bitcoin.it/wiki/Data_directory)
3) Remove the current wallet.dat file and put it somewhere safe (the desktop works fine)
4) Place the wallet.dat you want to import in the .bitcoin directory
5) Start bitcoin-qt.

Note: this method allows you access to the backup but does not merge the two wallets. If you want all your coins in the same wallet you need to send the coins from the wallet you don't want to use to an address in the wallet you do want to use.

Are you using an existing wallet.dat from the official Bitcoin client? or from another wallet application? bitcoin-qt only understands wallets that are in wallet.dat files. If you are importing from another wallet application you might have to import the private keys manually.

bitcoin-qt will automatically create a wallet.dat file on startup if one does not exist. Make sure that you have copied the correct wallet.dat file from the usb to the data directory (normally at ~/.bitcoin) and when you start bitcoin-qt you should see the balance (assuming that you are using the correct wallet file). You can see if you have the correct receiving addresses in "File>Receiving addresses...".

If the wallet.dat file is correct but bitcoin-qt is not reflecting the correct transactions, you might have to rescan the blockchain. You can start a rescan by typing following command from the terminal:

Code:

bitcoin-qt -rescan

It shouldn't do any harm to the wallet.dat file (Nevertheless, you should have a backup in case of emergency), but it does take quite a while to complete.
