Recovery tools and reinstalls carry different risks; some can remove apps or data. A verified backup and recovery key give you safer choices.
Protect your files first
Back up important files when possible. If the drive is encrypted, locate the BitLocker recovery key before recovery changes. Stop if storage appears to be failing or this is a work or school managed PC.
When this guide applies
Recovery tools and reinstalls carry different risks; some can remove apps or data. A verified backup and recovery key give you safer choices.
Check the exact Windows version and whether the PC is managed by a workplace or school before following instructions.
Steps
If Windows starts, copy irreplaceable files to a separate trusted drive or cloud location and confirm they open. Record account sign-ins and the BitLocker recovery key privately.
Record the result of the step before deciding whether to continue. A failed step is diagnostic evidence; it does not automatically justify a reset or reinstall.
Limits and stop points
Do not run write-heavy scans on a failing disk. If Windows cannot start and files are not backed up, ask a qualified data-recovery professional.
If the result does not match the guide, use the official reference below or contact the device maker with the exact error and steps already attempted.
