Boot to DOS in Windows XP

1.     Insert a blank floppy disk into your floppy drive and navigate to the drive on your computer (which is usually labeled A:).

2.     Right-click on the icon and select "Format..."

3.     A dialog will pop up. Select "Create MS-DOS Start Up Disk..."

4. Another dialog will pop up telling you that this format will erase all data on the disk.

5.     Click OK.

6.     When the formatting is done, restart your computer with the floppy disk still in the A: drive (or your floppy drive letter).

7.     After a couple seconds there will be a message saying in the usual, bland DOS text "Starting..."

8.     It should now show "A:>" or the corresponding drive.

9.     Now, you will be able to use MS-DOS!
