How do you put an OS on a floppy disk?

Specs: MS-DOS 3.2, 640KB
Hello, I wanted to know how do you put a operating system on a floppy disk? Is it just a matter of copying the operating system files onto the floppy disk or is there something else involved?

u can make an image of the original disk. But that probably wont fit on a floppy disk.

you cant really just copy the files because the OS is dependant on the hardware.

I don't know of any OS that will fit on a floppy disk. Many versions of Linux will fit on a CDR.

MS-DOS Boot Disk and of course Linux:

Generally you can not just copy the files because the boot sector needs to present!

Depends on the OS. Some need a special program to put hidden files in an exact place. I assume you mean an x86 computer so it does need to have part of the OS in an exact place on the disk.

Many people do use an image An image is an exact copy of some other disk and you use a program to replace it exactly like it was copied. rawrite/rawread is one and dd is another common program.

See menuetos for a complete OS with gui and network and browser on a disk. The old QNX floppy was still the best in my opinion.

Why did it take me over a year to phone in a problem to ATT?

Did you get the disks I sent to work? Did you determine if your floppy drive is OK?

You'd usually use the SYS command to copy the system files to a formatted blank disk since they need to be in a certain place on the disk. Then just use COPY to get the rest of the file on the disk.

You can also use DISKCOPY to make a duplicate of an existing disk.

I have some old dos versions copied to my hard drive but creating a bootable floppy from them can be a problem since the system files need to be in the right place on the disk and unless I boot with that OS I can't use its SYS command. In that case I copy the system files over those on a disk I already have--say 6.22--since the system files on that disk are already in the right place. But I have a problem with that method when there's a large difference in their system file sizes. Then I found out it's only io.sys that needs to be copied over the existing version on a working disk. Msdos.sys can just be copied to the disk as the next file. And it doesn't matter where command.com is on the disk.

So I use ATTRIB -S -H -R on the disk to expose the system files and delete msdos.sys and command.com. Then I copy io.sys from the version I want to the disk and it overwrites the one already on there. Then I copy msdos.sys to the disk as the next file and then command.com and the rest of the files.

That's how I created some of the disks I sent. Others I just used DISKCOPY and as I mentioned previously I tested them all. Anyway, maybe that will help if you've found some other working disks.

I have cleaned the floppy disk drive and tested the floppy disks on my desktop and they seem to be working in order. The only thing I can think of is that there is a more serious problem with the disk drive itself. Because you made the boot disks themselves I was wondering if they don't match up with the laptop's ms dos 3.2, could that be possible?

If you are having issues booting to a floppy verify the drive shows in the BIOS and you have it set before the hard drive in the boot order.

The drive could be bad or misaligned and not just dirty. But if it is good then it should boot up using a good disk. The system the drive is in shouldn't matter. I didn't test them in a 720 K drive but that shouldn't matter either. I do have some 720's in a couple of IBM model 30's I found at goodwill but they're at the bottom of a pile of other old PCs. If I get around to it I'll pull one out and see if it even works.

You might check ebay and see if you can find a similar laptop (I can't remember exactly what you had). Even a junker with a good drive would be enough.
