Solution: Windows Installation Stuck at 0%, 64%, or 100% – How to Proceed

🔍 Common reasons the install appears stuck

This usually happens due to:

• Damaged or incomplete installation media (USB/ISO)

• Conflicts caused by connected devices (printers, hubs, receivers, etc.)

• Memory or storage problems (RAM faults or disk errors)

• The installer working in the background (especially when it shows 100%)

• Firmware or BIOS settings that need updating (including Secure Boot / TPM settings on supported systems)

✅ What to do next

1. Wait a bit longer (especially at 100%)
   At 100%, Windows may still be finishing tasks in the background (drivers, setup tasks, final checks). If you’re stuck at 100%, wait at least 30–45 minutes before assuming it’s frozen.

2. Disconnect unnecessary devices
   Unplug anything that isn’t needed for installation, such as:

• External drives

• Printers

• USB hubs

• Wireless dongles/receivers

Then restart the installation process.

3. Recreate the installer USB
   If you haven’t already, rebuild your bootable USB using Microsoft’s installation tool:

• Create a fresh installer USB (8 GB+ recommended)

• Use a different USB drive if possible

• Plug it directly into the PC and prefer a USB 2.0 port when available

4. Optional (advanced): Update BIOS / reset firmware settings
   On some systems, outdated firmware or misconfigured BIOS settings can cause installation freezes. If you’re comfortable doing so, check your device manufacturer’s support page for a BIOS update or reset BIOS settings to defaults. If your device supports Secure Boot/TPM, confirm those settings are correctly configured for your Windows version.
