Purpose
Bare metal gives Kali direct access to the machine. It can be useful for dedicated lab laptops, wireless testing, and cases where VM overhead or USB passthrough causes friction. It also raises the cost of mistakes because rollback is not as simple as reverting a VM snapshot.
When This Option Makes Sense
Consider bare metal when the machine is dedicated to lab work, you need direct hardware access, or you are comfortable recovering the system from images and backups.
Advantages
- Direct hardware access
- Strong performance on capable hardware
- Useful for wireless adapters and dedicated lab laptops
Tradeoffs and Limitations
- No simple VM snapshot rollback
- Dual-boot and disk changes can affect the host
- Backups and external note storage become critical
What to Verify Before You Commit
- Disk layout and recovery media are understood before installation
- Notes and evidence are stored outside the Kali installation
- Power, sleep, and wireless behavior are reliable during long sessions
Common Mistakes
- Installing on the only daily-use laptop without an image backup
- Assuming performance removes the need for recovery planning
- Mixing personal files and lab artifacts carelessly

Summary
Running Kali on Bare Metal is a good choice only when its recovery, networking, and operational tradeoffs fit your study workflow.
