Why is Windows stuck in a restart or boot loop?
A boot loop can happen after a failed update, damaged boot files, a driver problem, unstable hardware or a storage issue. The goal is to avoid making the situation worse before important files are protected.
What the symptom can mean
When to stop DIY troubleshooting
Stop repeated repair attempts if the drive makes unusual noises, disappears from BIOS, or Windows recovery cannot see it. Data protection should come before reinstalling when files matter.
When professional diagnosis makes sense
If the simple checks do not identify the cause, diagnosis can prevent unnecessary parts replacement. Laptop Clinic serves NDG and Greater Montréal. Describe the symptom and what happened before it started; you do not need to know the technical name of the fault.
Useful details before a diagnosis
Note the exact computer model, when the problem started, and any recent change such as an update, drop, liquid spill, new part or new charger. If the problem is intermittent, a short video or photo of the error can help. For storage-related problems, always mention whether the files are important before any reinstall, reset, initialization or formatting attempt.
