Build a small emergency kit before you need it.
This guide expands the Facebook post into a practical workflow for beginners, home-lab users, and small-business owners who want to understand the trade-offs before changing a working system.
What this guide covers
- Your computer emergency kit
- Label it, store it, test it.
- Recovery USB — Labeled and tested
- Backup drive — Separate device
- Recovery codes — Private, not posted
- Device inventory — No secrets
Why it matters
The goal is not to memorize a product name or copy a command blindly. It is to understand what the change affects, verify it against an official reference, test it on spare hardware or a virtual machine when possible, and keep a rollback path.
A practical walkthrough
Protect the data first
A labeled recovery USB, an external backup drive, printed recovery codes, and a written device inventory. Keep the USB and drive somewhere you can find them; keep the codes somewhere private. Never post recovery codes, passwords, tokens, or serial numbers in comments.
Protect the data first
An inventory can be simple: device name, model, operating system, disk encryption status, backup location, and who to contact. Do not include secrets.
Protect the data first
Test that the USB boots and that the backup opens. A kit you have never used is a box of hope.
