When you open the System tool in Control Panel, and then click the Advanced tab in the System Properties dialog box to make changes to your System Startup options on a Windows Server 2003-based computer, you may receive the following error message:
Note To open the System Properties dialog box, click Start, point to Control Panel, click Performance and Maintenance, and then click System.
The C:\boot.ini file can not be opened. Operating System and Timeout settings can not be changed.
This problem may occur if the partition where Windows Server 2003 is installed is assigned any letter other than "C." This issue may occur in a dual-boot scenario or when the drive letters have been reassigned by a third-party program such as Citrix DriveRemap.exe.
Windows stores the System Startup options in the hidden Boot.ini file that is located in the root of the system partition. In this scenario, Windows incorrectly enumerates the drive letters on the system and uses the default path of C:\Boot.ini. Because "C" is typically used for the system partition, this problem does not occur on most systems, where this is a valid path.
