We can create ReactOS boot floppies using FATTEN utility and FreeLdr with:
as an example of command-line. However there are two problems
- if the FAT12 bootsector image fat.bin is built out of the source file reactos\boot\freeldr\bootsect\fatx.S, boot fails at the level of the bootsector, with the error "Load failed! Press any key to reboot..." (Cc Timo Kreuzer).
- if fat.bin is built out of the old source file reactos\boot\freeldr\bootsect\fat.S, the first sector of FREELDR.SYS loads and starts, but then the bootsector fails to load the rest of the image, and the message "Disk error" appears.
