�What is the chance that after restart it won't boot back?

# Resolve Critical Disk Space on Windows Server C: Drive

## Problem
A Windows Server 2008 system had critically low disk space on the C: drive with only 282 MB free out of 39.9 GB total capacity. The server had been running for over 211 days without restart. Tech A was concerned about restarting the server due to potential boot failure risks given the age of the system and critical disk space condition.

## Resolution
1. **Assess disk space situation** - Verify available space on all drives using Windows Explorer or NovaBACKUP Device tab
2. **Complete backup operations** - Ensure all backup processes finish successfully before taking any action
3. **Avoid restart when possible** - On older systems (2008 era) with critical disk space, evaluate restart risks carefully
4. **Consider disk cleanup alternatives** - Look for temporary files, logs, or other data that can be safely removed to free space
5. **Plan system replacement** - Systems in this condition should be considered for replacement or migration

The immediate issue was resolved by completing the backup process and avoiding the risky restart. However, the underlying disk space problem requires ongoing attention.
