What is one way to resolve a “missing hal.dll” error in Windows 7?
  1. Download Hal.dll from the Internet and replace it in the System32 folder.
  2. Copy Hal.dll from another computer and replace it in the System32 folder.
  3. Run Startup Repair from the Windows 7 installation DVD.
  4. Delete the Hal.dll file from the System32 folder.
Explanation
Answer: C - Running the Startup Repair utility from the Windows 7 installation DVD is one way to resolve a missing hal.dll error in Windows 7.

Key Takeaway:
When it comes to missing DLLs (or Dynamic Link Libraries), it is never good to copy them from the Internet or even another computer, since the version, author, date, and other factors can greatly change the specific DLL file. Also, due to how common a missing DLL file is, viruses often pop up in DLL libraries available online. Since Hal.dll is a file involved with startup (and it is located in the System32 folder), a good solution in this case is to run Startup Repair from the Windows 7 installation DVD. It is possible a simple reboot will also solve the issue, but that is the first troubleshooting step you should take in just about every instance anyway.
