You do not drag the file partlogic-0.6-img to your floppy.
You run the program RawWriteWin to mount this to the floppy. IT is an image of what should be on the floppy
you want the binary or executable, not the source code.
You are correct, the operating system which runs when you boot to the floppy or bootable cd is linux , the open source operating system. If they used windows or DOS they would have to pay licensing fees to microsoft and charge you for the program.
In reality many bootable cds etc use a linux based os .
You do not run this floppy, you put it in , shut down and restart. If your computer is set to boot to floppy before hard drive in the bios, it will boot to this and allow you to repartition your hard drive.
But it is pretty simple
Rawwritewin.exe direct download
Note that it will say floppy A as target (Floppy drive listed at the top of the program_)
You select the write tab
It will below have a place to put the path to the .img file you are using (use the box to right with three dots to browse if you do not know the path). You just click on write and it does the rest.
Now that floppy is a bootable floppy which will run a linux based operating system and partition logic. You just restart the computer and you can use it.
Make sure you choose the partition logic for floppy. If you choose the cd version it will be bigger and more complex with a nicer interface. You run your cd burning program and choose burn from an image and select the .img file as source. Note you do not burn a data cd, you are choosing to burn disk from image.
