A hard disk drive stores all the data and program files required for the operating system. HDD failures are common, and they can cause system crashes and prevent the server from booting.
Corrupted File System
File system corruption can occur due to various reasons, including unexpected shutdowns or improper shutdowns. This can cause data loss and prevent the server from booting.
Missing or Corrupted System Files
The operating system might fail to boot if itโ€™s missing critical system files or if the files are corrupted.
Hardware Issues
Issues with hardware components such as the RAM, power supply unit, or video card can prevent the server from booting.
Security Issues
Security breaches can compromise the operating system and cause booting issues.
Software Configuration Errors
Incorrect software configurations can prevent the server from booting, making it essential to ensure all configurations are accurate.
