PC formatted. I have the wallet.dat. How to recreate the situation?

[prgiorgio]

Hi. I'm searching for a guide for this topic, i can't find the right link.
Could someone link me to the correct guide?

MORE DETAILS:
I saved my wallet.dat in an external key,
i formatted my pc.

Now what am i supposed to do?
apt-get install the bitcoin client,
then?
creating the .bitcoin dir and putting inside the wallet.dat
before starting the client for the first time?

Also i have another pc with another wallet.
Can i copy the other files to avoid the all chain download?

Thank you in advance.
Giorgio

Yes, putting the wallet.dat in the ~/.bitcoin directory will allow you to keep your coins, and putting blk0001.dat and blkindex.dat in the same directory will avoid having to download the blockchain again.

Also the very own forum search can be quite useful, when people do use it!
The same goes for the bitcoin wiki...
