MS-DOS Install Issue

By quintar51 ·
I used to have MS-DOS on 3 floppy disks. They eventually went bad, so I got a friend of mine to email me the files from each of the disks. I then copied the files to 3 corresponding disks.

My problem is that when I try to boot from the 1st disk and start the DOS install, I get 'non-systems disk error'.

I don't have a DOS machine to use the 'format a: /s' command to make it bootable, and if I can't use that command through windows.

I also tried going to www.bootdisk.com and downloading the 'dos boot disk', but that doesn't start the setup, just starts the computer.

I was never a DOS guru. Is there anything else I can do??

you just need to add the hidden, system, read-only files: command.com io.sys and msdos.sys. copy those to the disk you want bootable. that's what happens during the /sys command. maybe your friend can email them to you off her first disk (she probably didn't have hidden files turned on)or you could download the dos boot disk image from bootdisk.com and create the disk and use it to sys yours, or manually sys it by copying those 3 files or copy the files on YOUR first disk over to the boot disk...oh, i am just being a snot now (smile)...just be sure your dos versions are the same...isn't there a useable version of DOS on wfw311 install disks...?

Format a floppy as a bootable disk from Windows (95 or 98 will work best)

Copy the DOS files onto the disk.
Answer yes to replace existing files.

Even though the files are on the disk, you need to set a flag in the FAT so that the disk is recognized as a bootable volume.
When you run the system command, you set the flag, and copy the system files to the drive.

After formatting the bootable floppy in Win 98, I then copied the files and replaced everything. When I boot up, it shows 'starting windows 98' and then I get an error saying that the COMMAND.COM file is corrupted.

Which version of DOS are we talking about? In every version I know of ealrier than 7, the two system files had to be in the first couple of sectors on the floppy in the correct order.

Hve your friend use a floppy imaging program such as 2file from PC Magazine (free) to make image files of his disks then you use the complementary program such as 2floppy to re-create it.

This is version 6.22. I never had so much trouble with this. My friend just copied the files using windows explorer, and he did select all hidden files as well.

you are hard to please this week! i still say get a DOS6.22 boot disk image from somewhere and see if it will boot without error then get the command.com off that. i think i have had that error corrupt command.com when inadvertently mixing files from win9x boot disk...

Sorry Sgt. not trying to be a pain in the *** here :)

it's just that I have all the necessary files on the Disk 1.

I'm willing to try anything anyone suggests. If nothing works, I'll end up buying it.

Try getting the DOS6.22 boot disk from www.bootdisk.com and then editing that first disk with the correct files from your list.
You need the correct version of command.com, msdos.sys and io.sys that you can only get from Dos 6.22.
When they were copied they might have missed the hidden files. I think diskcopy a: a: will make a good copy. DOS was a hundred years ago.
