Hi again,
I used CloneDisk to rip a RAW image of the booting DOM with FreeDOS. Mounted that with Qemu. Booted Qemu with the FreeDOS install image and installed FreeDOS to the image copied from the DOM. Then I used CloneDisk to write that image back to the DOM. "Missing Operating System".
Then maybe the real PC and QEMU were configured to use different drive geometries: For example QEMU supports LBA, but maybe your real PC BIOS did not support LBA or did not have it enabled? Have you tested whether things still booted in QEMU before you cloned the image back to the DOM? When in doubt, you can always skip the SYS step during FreeDOS install to keep most booting parts as they were in the previous raw image. Also, a "missing operating system" message can be a symptom of bad XMS, EMS or UMB driver configurations: Those might break proper disk access as soon as the driver loads or as soon as XMS / EMS / UMB are actually used. And when file access fails in the middle of config / autoexec, you may get messages complaining about missing files, while the files actually are still there. Things you can try: 1. Boot from floppy and SYS the DOM again. 2. Use F5 / F8 to skip all / part of the drivers to see if they caused your problem in their current configuration and 3. Check your PC BIOS and QEMU settings regarding LBA support and CHS geometries for the DOM to see whether they match nicely. You can also tell SYS to use or avoid LBA manually, but that should only be needed in exotic situations.
