What to Do When Windows 11 Won't Boot

Many users tried a lot of solutions for internal problems and still cannot boot up the computer. It is most likely that the problem is caused by an outside source. Thus, before performing any other repair for system issues, check if your peripherals are correctly installed. The monitor, power source and cables, external devices, motherboard, CPU, GPU, etc. could all be the cause of the issue.

If they are installed correctly, read on. The following methods are ranked by difficulty and solution efficiency.

Fix 1. Run Startup Repair

Missing or damaged system files is one of the reasons why you can't start the computer. To fix such a problem, you can resort to Windows Startuo Reoaur.

Startup Repair is a Windows built-in troubleshooter designed to resolve issues with booting up. It checks your system and repairs errors it discovers.

Step 1. Boot up your computer and hit "F11". (The key may differ according to different motherboard manufacturers.)

Step 2. Click "Troubleshoot > Advanced options > Startup Repair".

Step 3. Then, follow the instructions on the screen to execute a Startup Repair procedure.

Step 4. After the process is complete, restart your computer to check if the problem has been resolved.

Fix 2. Rebuild MBR

MBR errors can also prevent your computer from booting up normally. You may see an error message showing that there was a boot failure because the operating system could not be found. It could be MBR error 1, MBR error 2, or MBR error 3. Or, there is just a blank screen with no indication.
