I am thinking of creating my own OS. I downloaded bochs for a test machine, and now I need a 'floppy' to boot from (it boots from .img files). I need a way to create bootable disk images. I have neither physical floppies or a floppy drive. My requirements are:

I need a way to create a bootable disk image.

I need a way to manipulate files on the 'disk'.

The best solution I found was VFD, but I have Windows 7 64-bit, and VFD is explicitly designed to work only on 32-bit hardware. I searched high and low on Google and I couldn't find anything both free and useful.

Is there a 64 bit solution?

You should be able to use UltraISO. While it is not free, IIRC, the limits improsed on the trial version still allows making floppy images.

I'll delete this answer if my memory is wrong. Also, I may be getting confused with PowerISO. I have used both in the past, but it was a long time ago. – paradroid Oct 15 '11 at 21:49
Is it a limited-time trial? I couldn't find any info on the trial version. I do have a blank, unformatted floppy image created by bochs. – Kendall Frey Oct 15 '11 at 22:45
@kendfrey: IIRC, it is a feature-limited trial and not time-limited, where you can only make images of up to a certain (small) size. – paradroid Oct 15 '11 at 22:52
OK, thanks, I got a formatted bootable floppy disk image. – Kendall Frey Oct 15 '11 at 23:22

It's always a good idea to read user manuals. Chapter 8 of the user manual for Bochs points one to the Bochs WWW site where one can find listed two Win32 ports of MTOOLS, for starters.
