Windows 7: How do i create a MS-DOS boot disk

This post has been solved. I don't need any help now. I already have DOS-on-a-stick.

I formatted the recovery disk built in to the motherboard.???
In to the motherboard... what do mean?

Format a floppy disk

I am not understanding properly the first sentence, but , as your thread title says, you may try this ...
MS-DOS Bootable Flash Drive - Create

That recovery disk is useless since i have Windows 7 now. Plus i'm gonna put MS-DOS on that disk. But i do not have a floppy drive.

I think its the "recovery disk built in to the motherboard" part thats confusing people. Most motherboards don't have a "disk" built into them, the hard drive is external and connected by a cable. If you would post a snip of your expanded disk management window that might help. Also filling in your system specs in your profile would help.

Why do you want an MS-DOS boot disk? It's not a substitute for a recovery disk. You can't use MS-DOS to fix a Windows 7 installation because DOS can't read NTFS. You don't need separate recovery disks if you have bootable Windows 7 install media (DVD or flash drive). Windows 7's installation program can repair a broken install.

If you really want a DOS boot disk for nostalgia or experimental purposes, look at DOS remakes like Freedos.
