The above response is a bit cryptic, but essentially correct. In version 38, your speed dial entries are contained in the "Bookmarks" file, in the Win7 user's <AppData\Roaming\Opera Software\Opera Stable> folder. Copy it over to the same folder on your new machine. Then run Opera and look in the bookmarks manager (just click on the heart on the start page). Look under "Other Speed Dials" and you'll find a folder with your old machine's name that has all your speed dial entries in it. Click on it and they will all appear in the right pane. Select them all, then drag them to the "Speed Dial" folder.
