DOS system: Need to get a DOS Prompt

December 15, 2009 at 08:37:08
Specs: DOS os
System is DOS only. Runs ONE program. Removed that program to reinstall it. Now the problem: the install wasn't complete, the program won't run.

Config is set to start that program after booting the computer... the program just hangs... so, now I have a 20lb paperweight!

Is there a keyboard combo to force the program to close so I can get back to a DOS prompt?

Might help if you list some specs about the machine (including the version of DOS) and the program you're trying to run....

Usually Ctrl+C will breakout of most DOS programs. You could also try Ctrl+Pause/Break key. Some older apps used Ctrl+Z or Ctrl+E to terminate. Try these key combinations.

You could boot from a DOS disk and go into the AUTOEXEC.BAT file and put REM in front of the command that starts your program automatically. This is assuming you have a DOS disk to boot from.

Like said above, it would be handy to know which version of DOS you are running and the Name and Creator of the app that is being run.

Yeah, whatever it is, it's in autoexec.bat and maybe config.sys. You just need to edit it out.


Depending on your dos version F8 may work. Try tapping it before dos starts loading. If you get a menu choose 'step by step confirmation' and answer No to everything it asks to load. That should leave you at a c:\> prompt and you can run the EDIT command.

If F8 doesn't work you'd need a bootdisk, as already mentioned.

Can't remember exactly.
Press F5 or SHIFT+F5 on bootup. This will boot to DOS without using config.sys and autoexec.bat.

To bypass the CONFIG.SYS, and AUTOEXEC.BAT files during boot process of DOS, you need to press F5.

F8 allows you to selectively bypass commands in AUTOEXEC.BAT, and CONFIG.SYS.

Press the key of choice just before the Starting MS-DOS message.
