Method 1
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

1. When you receive the error message, press SHIFT+F10 to start a command session.
2. Type regedit.exe, and then press ENTER.
3. Click HKEY_LOCAL_MACHINE.
4. On the File menu, click Load Hive, and then load %Windir%\System32\Config\System.sav.
5. When you are prompted to specify a name, type Test.
6. Locate and then click the following key:
HKEY_LOCAL_MACHINE\Test\ControlSet1\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
7. Delete the UPPERFILTERS and LOWERFILTERS registry keys.
8. Repeat steps 6 and 7 for the other ControlSet# keys under the Test hive.
9. Click File, and then click Exit to quit Registry Editor.
10. If the path in the error message is the correct drive letter for the CD-ROM drive, click OK to continue the Setup program.
11. If you receive the error message again, the Setup program cannot correctly read from the CD-ROM drive, or the path information is incorrect. In this case, restart your computer and let the Setup program resume.

Method 2
If you cannot start Regedit.exe at the command prompt, and there is another available partition where you can install Windows on the hard disk, follow these steps:

1. Install Windows in the other partition.
2. Start the new installation of Windows, and then start Regedit.exe.
3. Follow the steps in method 1, but load the System.sav hive from the original Windows folder.

Method 3
If you are not using a retail Windows XP CD-ROM with a hologram (for example, if you are using a burned CD-ROM), try to run the Setup program from a retail CD-ROM with a hologram. To verify this, start the computer by using Recovery Console, and then check the C:\$win_nt$.~ls folder. Look for the Asms folder. If the folder is missing or the files that it contains are zero bytes, the CD-ROM was not burned correctly.
