Quick fix: Windows 11 stuck at OEM logo (Dell, HP, Lenovo) means boot issue: corrupted bootloader, drive failure, or hardware issue. Force restart 3 times to enter Recovery Environment → Troubleshoot → Advanced → Startup Repair. If fails: Command Prompt → bootrec /fixmbr, bootrec /fixboot, bootrec /rebuildbcd. For hardware: test disk via BIOS or Linux Live USB.

Boot freezes at manufacturer logo before Windows loads. Causes: bootloader, hardware, recent update. Recovery Environment’s Startup Repair and bootrec commands are first steps.

Symptom: Windows 11 stops at manufacturer logo; want to force boot.
Affects: Windows 11.
Fix time: ~30 minutes.

What causes this

Stuck at OEM logo = BIOS finished POST, transferring to Windows boot, but Windows loader fails. Causes:

Corrupt bootloader (after update / partition error).
Drive failure.
BitLocker issue (requires recovery key entry).
Hardware issue (RAM, motherboard).
BIOS settings change.
External device blocking boot (USB drive).

Method 1: Force Recovery Environment

The standard route.

Hold power button to force shutdown.
Power on. As soon as you see OEM logo or before Windows loads: hold power again to shutdown.
Repeat 3 times.
4th boot: Windows enters Automatic Recovery / Recovery Environment.
Pick Troubleshoot → Advanced options → Startup Repair.
Walk through. Pick account, enter password.
Startup Repair runs. Detects and fixes common boot issues.
Reboot. May work now.
If not: re-enter Recovery → try other Advanced options.

This is the standard fix.

Method 2: Manual bootrec via Command Prompt

For boot repair.

Recovery → Troubleshoot → Advanced → Command Prompt.
Identify Windows drive: diskpart → list vol → note drive letter.

Run:

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

For UEFI:
```
bcdboot C:\Windows /s C: /f UEFI
```
For chkdsk: chkdsk C: /f /r. Takes 1-4 hours.
Exit. Restart.
For chronic boot fail: System Restore via Recovery → pick restore point.
For Reset This PC: last software resort. Keep my files or remove everything.

This is the manual repair.

Method 3: Test hardware

For non-software cause.

Remove external USB drives (may block boot).
Power off PC.
If laptop: check battery + charger.
Try booting after unplugging all USB devices.
For chronic: boot to BIOS. Run diagnostic (most modern BIOS have).
For Dell: F12 at boot → Diagnostics.
For HP: F2 / F10 → System Diagnostics.
For Lenovo: F10 / Esc → Diagnostics.
For testing drive: boot Linux Live USB → check disk SMART.
For RAM: Windows Memory Diagnostic or MemTest86 from USB.
For motherboard: visible damage check; CMOS battery reset.

This is the hardware route.

How to verify the fix worked

Windows boots past OEM logo to login.
System functional.
No recurring stuck.
Event Viewer post-boot shows clean startup.

If none of these work

If still stuck: BitLocker recovery: need key. Visit account.microsoft.com/devices/recoverykey from another device. Enter on PC. For chronic boot fail: drive failed. Replace + restore from backup. For UEFI corruption: BIOS reset. Remove CMOS battery for 5 minutes. For Surface devices: Surface Recovery Image USB. For dual-boot: GRUB may have broken Windows entry. Boot Linux to repair. For chronic stuck at logo despite hardware OK: clean install Windows. Backup data via Linux Live USB first if possible. For warranty repair: contact OEM if covered.

Bottom line: Force restart 3 times to enter Recovery → Startup Repair. If fails: Command Prompt → bootrec commands. Test hardware via BIOS diagnostics. Recover BitLocker key if PC prompts.
