Operating Systems: Dealing corrupt OS file

A user's computer cannot boot because an operating system file is corrupt.
What should you try first to resolve the problem?
1. Boot to Safe Mode and use System Restore.
2. Boot to Recovery Console and use System Restore.
3. Boot to Recovery Console and run Chkdsk.
4. Boot to Safe Mode and run Chkdsk.

Explanation : You should boot to Recovery Console and run Chkdsk. Because an operating system file is reported as corrupt, you will need to boot to Recovery Console. To do so, insert the Windows XP installation disc and choose R when prompted whether you want to install Windows XP or repair an existing installation. Next, run Chkdsk with the /r option to locate bad sectors and repair the file. If that does not work, you will probably need to reinstall Windows or restore from backup.
You cannot boot to Safe Mode because an operating system file is corrupt. Safe Mode loads a minimum set of drivers, but it still requires that the operating system files be valid.
You cannot use System Restore from Recovery Console. System Restore requires Windows XP. Also, System Restore is used to recover from configuration problems caused by installing applications or updating drivers. It does not perform a check disk.
