Well, I got FreeDOS onto a floppy, and found the Smart Boot Manager thing, but I saw no options to fix my mbr or anything. except for one Restore Repvious MBR option, which didn't do anything, and I saw the "Install Smart Boot Manager" option, but it did nothing.

Then I ran it in DOS mode, and I tried fdisk /fixmbr, and other fdisk help things, but it didn't work.

So, you know the command to fix a master boot record in FreeDOS?
