A Davie inquiry described a Samsung Galaxy Book4 Ultra that flashes the Samsung logo for less than a second and then stops. That message does not prove a Windows problem, storage problem, power problem or board fault. I would protect the files first and avoid a reset until the computer is evaluated.
Stop using or charging the laptop if the case is swollen or opening, it is unusually hot, it smells burnt, it was exposed to liquid, the charger is damaged, or there is smoke or hissing. Disconnect power when it is safe to do so and get a responsible next step.
Write down exactly what happens
A logo that flashes once is different from a laptop that reaches a Windows sign-in screen and restarts. Note how long the Samsung logo stays visible, whether the charging light, keyboard or fan responds, and whether the screen goes black or the whole computer powers off.
Also mention a recent Windows update, drop, liquid exposure, overheating or previous repair. Do not keep forcing the power button again and again just to reproduce the symptom. Those details help separate a startup problem from a screen, power, storage or board-level problem without guessing the part.
- Exact Galaxy Book model and model number
- How long the Samsung logo appears
- Charging light, keyboard, fan and screen behavior
- Any recent update, drop, liquid exposure or overheating
- Whether Windows Recovery ever appears
- Which files are not backed up
If Windows Recovery opens, try Startup Repair before a reset
Samsung says repeated failed starts may bring a Windows computer into the Windows Recovery Environment. If that screen opens normally, Microsoft puts Startup Repair under Troubleshoot, Advanced options, Startup Repair, then Restart. Let that process finish before deciding that Windows must be erased.
Do not repeatedly interrupt startup just to force the recovery screen if the laptop is unstable, hot, wet or making unusual sounds. A computer that will not stay powered long enough for recovery needs evaluation instead of more button attempts.
Use Safe Mode only when the recovery menu is available
Microsoft places Safe Mode under Troubleshoot, Advanced options, Startup Settings, then Restart. Safe Mode can help identify a recent driver, update or startup-program problem, but it does not repair a damaged drive, charging circuit or main board.
An encrypted computer may ask for its BitLocker recovery key before some recovery options open. Do not guess at the key, share it in a website form, or let anyone promise a password bypass. Keep account passwords, PINs and verification codes private.
Protect the only copy of your files
If the laptop contains the only copy of important photos, business files or school work, say that before any reset or recovery process begins. Samsung Recovery can provide backup and restore options on supported PCs, but a factory recovery or Windows reset can remove programs, settings and data depending on the option used.
I would not erase the computer just to see whether the Samsung logo changes. A normal startup repair and a data-recovery evaluation are different priorities. Neither the failed part nor a recovery result should be promised before the computer is inspected.
Bring the details that make the evaluation useful
Bring the Galaxy Book and its original or known-compatible charger when it is safe. Tell us the exact model, the logo behavior, what happened before the problem began, which recovery screens appeared, and whether preserving the files comes first.

Common questions
Does a Samsung Galaxy Book startup loop mean the drive is dead?
No. Windows, an update, power delivery, storage, memory and board-level faults can produce similar startup symptoms. The exact computer needs evaluation before a failed part is named.
Should I reset a Galaxy Book that flashes the Samsung logo?
Not when the files matter and are not backed up. Try Microsoft Startup Repair only if the recovery menu opens normally, and explain the data priority before any reset or factory recovery.
Can Phone Repair Guy quote a Galaxy Book startup problem from a video?
A video can show the symptom, but the exact model, charger, damage history and computer condition still matter. A responsible repair path, price and timing may require inspection.
Can BitLocker block Windows recovery options?
Some recovery tools may require the BitLocker recovery key on an encrypted computer. Keep that key private and do not submit it in a public message or quote form.
