Reinstalling Windows is the solution when it won’t start, but first confirm it’s not a temporary issue. 2. Create a bootable USB installer using another PC and an 8GB or larger USB drive with the Windows Media Creation Tool. 3. Boot from the USB by accessing the boot menu via keys like F12 or Delete, or adjust BIOS/UEFI settings if needed. 4. In setup, choose Custom install, select and format the target drive, then proceed with installation which takes 15–30 minutes. 5.

This step-by-step process ensures a successful Windows reinstallation when facing boot failure.

If your Windows won’t start, reinstalling might be the most effective way to get your system back on track. This guide walks you through the practical steps needed to reinstall Windows when it fails to boot — no fluff, just what you need to know to get going.

1. Check if It's Really a Boot Issue

Before jumping into a full reinstall, make sure Windows isn’t just stuck or showing an error message. Sometimes it looks like it won't start, but it's just a corrupted file or driver causing the issue.

• If you see a blue screen with an error code, try searching that code online — it might point to a fix.
• Wait longer than you think you should — sometimes startup takes time after an update or crash.
• If you hear fans spinning and nothing shows up on screen, check your monitor connection or try another display device.

Only proceed with reinstallation if you're confident it’s not a temporary glitch or hardware issue.

2. Create a Bootable USB Installer

To reinstall Windows, you’ll need a working computer and a USB drive (at least 8GB).

Here’s how to create a bootable USB:

• Download the Windows Media Creation Tool (or Windows 11 version if applicable).
• Plug in a USB drive and run the tool.
• Choose “Create installation media for another PC.”
• Select your preferred language, edition, and architecture (usually 64-bit unless you’re certain otherwise).
• Let the tool format the USB and copy the files.

Once done, you have a bootable installer you can use on the broken machine.

3. Boot from the USB Drive

Getting your PC to boot from the USB might require a few extra steps.

• Insert the USB stick into the affected PC.
• Turn on the machine and immediately start pressing the key to open the boot menu. Common keys are F12, F10, Esc, or Delete — look at the startup screen or your motherboard manual if unsure.
• From the boot menu, select your USB drive as the boot option.

If the boot menu doesn’t show up or your system ignores the USB:

• Try different USB ports (preferably USB 2.0 for compatibility).
• Enter BIOS/UEFI settings (usually via Del or F2) and manually change the boot order.

Once you successfully boot from the USB, you'll land in the Windows Setup environment.

4. Reinstall Windows from Scratch

Now that you're in the setup, you can begin the actual reinstall process.

• Choose your language and click "Install Now."
• Skip product key entry if you don’t have one handy — Windows will attempt to activate automatically later if the machine has a digital license.
• When asked about installation type, choose Custom: Install Windows only (advanced).
• Select the drive where Windows was installed before (typically the largest partition labeled System Reserved or similar).
• Format the drive if needed — note this will erase everything on it.
• Proceed with the install — it will take 15–30 minutes depending on your hardware.

During installation, Windows will reboot several times. Don’t remove the USB until the setup finishes.

5. What to Do After Reinstalling

Once Windows is freshly installed:

• Make sure all drivers are updated — especially chipset, graphics, and network drivers. You can download them directly from your PC/laptop manufacturer's website.
• Connect to the internet — this helps with automatic activation and updates.
• Run Windows Update to bring your system up to date.
• Restore any backed-up data from an external drive or cloud service.

If you didn’t back up anything before reinstalling, recovery options are limited unless you used third-party backup tools or cloud storage.

That’s basically how you reinstall Windows when it won’t start. It’s not overly complicated, but there are enough small steps that skipping one can throw things off. Take your time, double-check each step, and you’ll be good to go.
