Boot the 3.X configuration of Amiga Forever, then press F12, go to Hard Drives and use the "Add Harddrive" button to add the new CF card to WinUAE, click Reset. Now you can use
http://thomas-rapp.homepage.t-online.de/downloads/tsgui.lha to write the image copy to the CF card. In order to select the unpartitioned drive, you need to choose "select raw device" from the menu. The new CF card must be as big as the HDF file or bigger. If it's bigger, the additional space cannot be used.
Before you can do this, you might need to clean the new CF card if it's already formatted for Windows. You can try with Windows Disk Management (right-click on My Computer, and select Manage, then select Disk Management) to remove all partitions, but better is the DiskPart command line tool with its sub command CLEAN.
If the Add Harddrive button is greyed out, you need to run WinUAE as administrator. Find winuae.exe, right-click it and select "Run as Administrator".
