I have a HD with GNU/Linux and FreeDOS flashdrive. I want to place those FreeDOS partition (2GB) on my HD.

fdisk, dd, all things are o'key, but I can't make my GRUB load those OS. I was try all of the things from the Internet - I have ten FreeDOS strings in GRUB and no one is working. When I run update-grub, os-prober says that FreeDOS found and make this grub.conf thing: set root (hdx,x) chainloader +1 It doesn't work. parttool, drivemap, linux16 and some other things fom Internet also doesn't work.

upd. This line it shows after boot (if don't go into reboot of course): FreeDOS FAT kernel GO!

  • 1. can you boot freedos from the USB flash drive? 2. did you make the HDD partition bootable with `sys` in freedos? 3. if you don't need to save any files to the freedos image while running it, you can use `memdisk` from `syslinux` to boot an ISO image containing freedos (that's what I do to make bootable DOS images, e.g., for flashing BIOS) – cas Dec 31 '17 at 03:05
  • 1. Of course I can boot from USB 2. No, I haven't heard about it. It will write right into bootsector and break my grub, isn't it? 3. No way, I need fully functional OS with rw. – J. Doe Dec 31 '17 at 07:55
