You may encounter one of the following symptoms with Windows:
After you make a change to your Windows environment your computerboots to a command prompt rather than into Windows.
Changes you make to entries in the Msdos.sys file may not seem to take effect.
When you perform a step-by-step boot and press either Y or N when you are prompted "Process your startup command file (AUTOEXEC.BAT)," youreceive a message stating "Too many parameters" followed by the prompt"AUTOEXEC [Enter=Y,Esc=N]." No matter how you answer these prompts, Windows boots to a command prompt and does not prompt you to load the graphical user interface (GUI).
When you start your computer, it boots to the Windows boot menu instead of booting into Windows, even though the Msdos.sys file contains "bootmenu=0" or the Enable Startup Menu box is not checked on the General tab of the Advanced options for the System Configuration Utility (MSConfig).
There is a Winboot.ini file in the root folder of the boot drive thatcontains "BootGUI=0" in the [Options] section.
If the Winboot.ini file exists, it is processed instead of the Msdos.sysfile. The Winboot.ini file is created by Windows Setup to ensurerestartability or to display a warning when there is an operation thatneeds to be manually restarted. When the operation is complete, theWinboot.ini file is normally deleted, and the Io.sys configuration settingsare read from Msdos.sys.
NOTE: The Winboot.ini file is a hidden file.
If your computer boots to a command prompt only and no error messages aredisplayed, you can safely delete the Winboot.ini file and restart yourcomputer.
To delete the Winboot.ini file, follow these steps:
At an MS-DOS prompt, type the following command in the root directory
where drive is the drive where the Winboot.ini file is located.
Answer yes by typing y when you receive a prompt "Delete file 'winboot.ini'?"
Restart your computer.
