vbr(volume boot record) to floppy disk

[chris70]

The ms dos boot disk can be created by creating a volume boot record in the volume boot sector of the disk. This automatically makes some program in windows or cmd, dos shell with format / s or sys command.
My question is ..... i could create vbr with hex \ disk editor and with assembler maybe ......?

It is not clear what you need to do.
Is this for educational uses?
Is this needed for a useful project?
MS-DOS has been retired for some time and  is not often used for any new application.

When people come here with MS-DOS questions is is often about maintenance to an old system that must be kept running. If you are using a computer that needs a boot floppy disks that can boot, the process is done at the time you format the floppy.

First you have to boot up with a floppy that already has both the system and the needed utilities. You insert a new or old floppy in the B: drive and issue a command to format and systematize the floppy in the second drive.
format b: /s
The will write the needed data into the proper place on the floppy.
Is that what you wanted to know?
