<p>I just did it in Windows.  Download Bootstrap.dat, then look for C:\Users\Your Name\AppData\Roaming\Bitcoin and put the file there.  Bitcoin will automatically find it and load from it.  Good luck.</p>

<p>Once I have the 9+ Gb bootstrap.dat file downloaded, how do I use it? I'd like to attempt mining without joining a pool; do I have the right file for a solo effort? I can use Windows or Linux so either one in the answer will be fine.</p>

Your talking about mining with the Bitcoin-Qt client, in linux "~/.bitcoin/" and in Windows find the AppData hidden directory. You can start Bitcoin-Qt and let it create the directory and stop it, remove everything inside for a clean beginning and move bootstrap to this directory.
