Is it possible to have menuetOS on a harddrive and if it is how can i do it.

See instructions in file /source/app.zip/boot64hd.asm
I recommend a completely empty HD for first time installation tests.
HD installation will be automated later.

I don't understand where this is located /source/app.zip/boot64hd.asm

could you please be specific. THX very much

-Download the compressed imagefile, unpack it and write it to the A: floppy (or use the installer)
-Once the image is written, open the A: drive and browse to the "source" folder. Inside you will find app.zip containing the file boot64hd.asm. open it with a text editor and read the instructions.

-If you still want to go on after reading the instructions, use fasm to assemble (compile) the boot64hd.asm file.
-use a hex editor (like hxd) that can open physical drives to write the resulting file to the first sector of the floppy disk.

Okay, I know this is a delayed response, but ...

• get ATV's UNIMG.COM (DOS tool to unpack 1.44 MB floppy image, no LFNs though)
  
• find the above-mentioned file in the corresponding dir created
  
• use something like WDE.COM (DOS raw sector editor) to write the boot sector to a floppy
  

Both of these tools should work even in WinXP (for floppy drives, at least).
