Setup could not locate the Windows installation you want to upgrade.
Contact your system administrator.
- Setup looks for a valid path to the registry files using the C:\Boot.ini file.
- Setup loads the System registry hive for each operating system entry found in the Boot.ini file and extracts the Setup\UniqueID:REG_SZ:C:WINNT\Unique_IDvalue.
- Setup compares the UniqueID entry in the System hive with the c:\$win_nt$.~bt\winnt.sif file's uniqueID entry under the [data] section. After a match is found, Setup continues with the next step for that Boot.ini installation.
- Setup loads the Software registry hive of the installation found, and checks for a valid ProductID (PID).
- Setup checks for a %SystemRoot%\System32 folder. The Ntoskrnl.exe and Ntdll.dll files must be present.
- Setup checks for a %SystemRoot%\System32\Drivers folder.
- Open the Boot.ini file with Notepad (or boot to Recovery Console) and make sure a valid ARC path is defined that points to the previous installation. For additional information, click the following article number to view the article in the Microsoft Knowledge Base: 155222 How to determine the ARC path
- Use Registry Editor (Regedt32.exe) to view the unique ID setting in the following location, and compare it to the UniqueID entry in the c:\$win_nt$.~bt\winnt.sif file:HKEY_LOCAL_MACHINE\System\Setup\uniqueid
- Use Registry Editor (Regedt32.exe) to view the ProductID setting in the following location:HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion ProductIDThis must contain a valid PID in the form of AAAAA-BBB-CCCCCCC-DDDDD.
- Check the file permissions on the directory structure if you are using the NTFS file system. Make sure that SYSTEM has full control.
- Rename $win_nt$.`bt to any different name, and then rename $winnt_$.`ls to any different name.
- Create a "dummy" directory structure on a separate drive or partition (for example, D:\Wintest\System32...) and copy the required files to the new directories. Then, using Ntbackup.exe, create an emergency repair disk (ERD) and choose the option to also back up the registry files to the repair folder. Using a copy of the registry files in the current %SystemRoot%\Repair\Regback folder, populate the "dummy" ...\Config folder with the system and software files. Finally, create a C:\Boot.ini file entry to represent the "dummy" directory structure. Restart the computer. If Setup recognizes the "dummy" structure as a valid installation to continue the upgrade, you can assume that all the requirements are met, but that you need to troubleshoot the original directory structure for problems.
