Using GRUB
GRUB error messages:
- If an error occurs in part of the boot process under GRUB’s control, an error message is generated, often with log information about it.
- GRUB can even allow the user to regain some control of the system to attempt to debug the problem without having to reboot.
- In most cases, however, the error information generated will need to be investigated and GRUB can then be restarted in interactive mode to give information to the boot process manually to fix or bypass the problem.
- Because GRUB is more than just a simple boot loader, it provides more control and allows direct manipulation of the process.
