DOS isn’t widely used anymore, but you’re still likely at some point to need to boot into a DOS environment. Windows’ built-in formatting utility lets you create a DOS-bootable floppy drive, but not a USB drive. Here’s how to get around that.RELATED:DOS may be a relic of the past, but you wouldn’t know that from reading instructions written by manufacturers for, firmware-updating utilities, and other low-level system tools. They often require you to boot into DOS to run the utility. We once formatted our floppy disks with MS-DOS using the format utility built into Windows, but most computers don’t have floppy disk drives anymore. Many no longer even have optical disc drives. Fortunately, there’s a free third-party utility that lets you quickly create a DOS-bootable USB drive.

Step One: Use Rufus to Format Your USB DriveWindows’ built-in formatting utility doesn’t allow you to select the “Create an MS-DOS startup disk” option when formatting a USB drive—the option is grayed out in Windows 7 and not available at all in Windows 8 and 10. Instead, we’ll be using a tool named Rufus.
It’s a fast, free, lightweight application that includes FreeDOS.RELATED:First, download and launch it. Rufus is a that doesn’t require any installation—you will see the Rufus application as soon as you launch the downloaded.exe file.Creating a DOS-bootable USB drive in Rufus is simple.
First, connect your USB drive to the computer and select it in the “Device” dropdown menu.Note that this process will erase the contents of your USB drive, so make sure you’ve backed up any important files on the USB drive first.RELATED:From the “File System” dropdown menu, choose the “FAT32” format. The DOS option requires FAT32 and isn’t available for the other file system options like.Select the “Create a bootable disk using” option and then choose “FreeDOS” from the dropdown menu next to that option.Click the “Start” button to format the disk and copy the files necessary to boot into FreeDOS.The formatting process should be extremely quick—usually a matter of seconds—but it can take longer depending on the size of your USB drive. Step Two: Copy Your Files OverYou have probably created this boot drive because you have a DOS-based program to run, such as a BIOS update utility or another low-level system program. To actually run these files from DOS, you will need to copy them over to your newly-formatted USB drive.
For example, you may have a BIOS.BIN and FLASHBIOS.BAT file you need to run in DOS. Copy these files into the root directory of the USB drive after formatting it. Step Three: Boot Into DOSRELATED:You can now boot into DOS by restarting your computer with the USB drive connected. If your computer does not automatically boot from the USB drive, you may need to or use a boot menu to select the device from which you want to boot.Once you are in DOS, you can run the program you copied to your USB drive by typing its name at the DOS prompt. Follow any instructions provided in the manufacturer’s documentation to run the application.RELATED:These utilities still use DOS to ensure they have low-level access to the hardware without any other programs interfering or Windows getting in the way. This helps ensure BIOS updates and other low-level operations work properly. You also could use a bootable USB drive to run old DOS applications, but that tends not to work so well. You would be much better off.

Contents.History The FreeDOS project began 29 June 1994, after announced it would no longer sell or support MS-DOS. Who at the time was a student posted a manifesto proposing the development of PD-DOS, a publicdomain version of DOS. Within a few weeks, other programmers including and joined the project. Between them, a kernel (by Villani), the command line interpreter (by Villani and Norman), and core utilities (by Hall) were created by pooling code they had written or found available. For some while, the project was maintained by Morgan 'Hannibal' Toal.

There have been many official pre-release distributions of FreeDOS before the final FreeDOS 1.0 distribution. GNU/DOS, an unofficial distribution of FreeDOS, was discontinued after version 1.0 was released. Distribution FreeDOS 1.1, released on 2 January 2012, is available for download as a CD-ROM image: a limited install disc that only contains the kernel and basic applications, and a full disc that contains many more applications (games, networking, development, etc.), not available as of November 2011 but with a newer, fuller 1.2. The legacy version 1.0 (2006) consisted of two CDs, one of which was an 8MB install CD targeted at regular users and the other which was a larger 49MB live CD that also held the source code of the project. Commercial uses FreeDOS is used by several companies:. preloaded FreeDOS with their n-series desktops to reduce their cost.

FreeDOS's default text editor—a clone of the with added featuresis fully supported and is the preferred format for the boot drive. Depending on the used, up to four Logical Block Addressing (LBA) hard disks up to 128 GB, or 2 TB, in size are supported. There has been little testing with large disks, and some BIOSes support LBA but produce errors on disks larger than 32 GB; a driver such as OnTrack or EZ-Drive resolves this problem. FreeDOS can also be used with a driver called LFNDOS to enable support for Windows 95-style long file names, but most old programs before Windows 95 do not support LFNs, even with a driver loaded, unless they have been recompiled. There is no planned support for NTFS, or, but there are several external third-party drivers available for that purpose.
To access ext2 file systems, LTOOLS, a counterpart to, can sometimes be used to copy data to and from ext2 file system drives.
