Sorry for the inconvenience. Known Navigation header breakage, its being "rebuilt."
There may be other unforeseen breakage primarily in the handbook portion of the wiki.
The Table Of Contents section of each "PC-BSD® Users Handbook" page may be the best workaround.
ImgBurn is an easy to use image burner for Windows that is available for free download. After installing and launching ImgBurn, select "Write files/folders to disk" from the main menu, seen in Figure 188.8.131.52a:
Figure 184.108.40.206a: Initial ImgBurn Screen
You can then use File -> Browse for a source file... to select the .iso file to burn. Double-check that Mode -> Write is selected; once selected, your screen should look similar to Figure 220.127.116.11b. Once a blank media is inserted into the DVD drive, it should show as the Destination. Simply click the Write icon in the lower left corner to begin the burn.
