Versions 9 and 10 of FreeBSD will not boot as an ISO, but the 1.63 version of Easy2Boot and a new MPI Tool Pack v0.044 or later supports FreeBSD 9 and 10 'memstick' images. For GhostBSD, download the .img files and not the .iso files. For MidnightBSD, use the 'memstick' download.
The procedure is to use the MakePartImage process, but as the FreeBSD memstick.img files are already in the correct format for a FreeBSD partition, the .img files don't actually need converting or modifying!:
1. Create a new empty folder on the Windows Desktop (or anywhere else).
2. Drag-and-drop the empty folder onto the MPI_FAT32 MPI Desktop shortcut to make a 30MB (or as small as possible - e.g. 10MB) partition image with no payload. If prompted for a target file, use a filename with either a .imgPTN or .imgPTNA5 file extension - e.g. FreeBSD_10_1.imgPTN or FreeBSD_10_1.imgPTNA5.
Do NOT use a filename that has any dots in it because it will also appear in the E2B Menu - e.g. FreeBSD10.1.imgPTNA5 would not be a good name because the 'FreeBSD10.1' file (see below) would also be visible in the menu!
3. Copy the new .imgPTN file to a menu folder (e.g. \_ISO\LINUX, a 2nd level folder - NOT \_ISO\LINUX\MNU.
4. Copy your FreeBSD memstick .img file to the same folder that the .imgPTN file is in and rename it to match the name of the .imgPTN file - e.g.
FreeBSD_10_1 (NO FILE EXTENSION OR DOTS - e.g. 700MB memstick.img file renamed to match with no file extension)
