The lesson

A Linux live USB, such as Ubuntu's, runs from the USB stick without installing anything.

It can test hardware, read Windows drives and copy files to an external drive when Windows will not start (encrypted drives need the recovery key).

Work read-only where possible and copy data before attempting repairs.

Step by step

  1. Create a live USB.
  2. Boot the lab computer from it.
  3. Open the Windows drive.
  4. Copy files to an external drive.

Practice activity

Rescue files from the lab computer using the live USB.

Expected result: Files copied and verified on the external drive.
