Short for Emergency Repair Disk, an ERD is a diskette that creates backups of system files and settings and helps troubleshoot and fix issues for Windows NT and Windows 2000 users. The ERD is used in conjunction with the Windows repair option and prompts for the diskette when needed. Note: The ERD is not to be confused with a standard boot diskette as it cannot be used alone.
- Verifying the boot sector is not corrupt.
