Windows 11 is Crashing During Installation [Easy Fixes]
Installing Windows 11 should feel like a straightforward upgrade or fresh setup, but for many users, it turns into a frustrating loop of freezes, restarts, or full system crashes. This usually happens during the initial setup phase, right after booting from USB or while the installer is copying files. The good news is that these crashes are almost always caused by fixable issues like incompatible hardware settings, corrupted installation media, outdated BIOS firmware, or unstable system memory.
When Windows 11 crashes during installation, the system is essentially failing to create a stable environment for setup to run. That means the problem is usually not Windows itself, but something underneath it, like firmware settings or hardware stability.
In this guide, we will go step by step through the most reliable fixes used by tech enthusiasts and IT technicians to get Windows 11 installed successfully without interruptions.
Let’s go for it!
Windows 11 is Crashing During Installation [Fixes]
If Windows 11 is crashing during installation, the most effective fix is to verify system compatibility, recreate the installation media, and reset BIOS settings to default. Start by confirming that TPM 2.0 and Secure Boot are enabled in BIOS, then recreate your USB installation drive using the official Media Creation Tool.
Next, reset the BIOS to default settings to remove instability caused by overclocking or incorrect configurations. After that, test your RAM for errors and disconnect unnecessary peripherals before reinstalling Windows 11. In most cases, installation crashes are caused by unstable memory, corrupted boot media, or incompatible BIOS settings rather than the Windows installer itself.
Step 1: Verify Windows 11 System Requirements in BIOS and Windows Setup Compatibility
The first thing to check is whether your PC actually meets Windows 11 requirements. Even if installation starts, unsupported hardware can cause random crashes during setup.
To do this, restart your PC and enter BIOS by pressing Del, F2, F10, or Esc, depending on your motherboard brand. Once inside BIOS, go to Settings > Security > Trusted Computing and confirm that TPM 2.0 is enabled. Then navigate to Boot > Secure Boot and make sure Secure Boot is enabled as well.
If either TPM or Secure Boot is disabled or missing, Windows 11 can become unstable during installation. Also, check your CPU compatibility using another working PC or by running Microsoft’s PC Health Check tool if you can boot into an existing system.
After confirming compatibility, save changes using Save & Exit > Save Changes and Reset. This ensures the system is aligned with Windows 11 requirements before continuing installation.
Step 2: Recreate Windows 11 Installation Media Using the Official Tool
A very common cause of installation crashes is a corrupted or incomplete USB installer. Even small file corruption can cause the setup to freeze or restart unexpectedly.
To fix this, create a fresh installation USB. On a working PC, download the official Windows 11 Media Creation Tool from Microsoft. Insert a USB drive with at least 8GB of space.
Open the tool and go through Create Installation Media > Select Language and Edition > Choose USB Flash Drive > Select Your USB Device. Let the tool rebuild the installation media completely.
Once done, safely eject the USB using File Explorer > Right Click USB Drive > Eject.
Now plug it back into your target PC and boot from it by pressing Boot Menu Key (often F12 or Esc) > Select USB Device. A fresh installer reduces the chances of crashes caused by damaged setup files or incomplete ISO downloads.
Step 3: Reset BIOS Settings to Default and Disable Overclocking
Unstable BIOS settings are one of the most overlooked causes of Windows installation crashes. Overclocking CPU or RAM may work in daily use, but fail under installation load.
To fix this, restart your computer and enter BIOS using the Del or F2 key during startup. Once inside, navigate to the Exit or Save & Exit section > Load Optimized Defaults or Load Setup Defaults.
If you previously enabled overclocking, XMP profiles, or manual voltage adjustments, disable them. Specifically, go to AI Tweaker or Overclocking Settings > Disable XMP Profile > Set CPU Ratio to Auto.
Save changes using Save & Exit > Save Changes and Reset.
This ensures your system runs at stable factory settings during installation. Windows setup is very sensitive to memory instability, and even small overclocking errors can trigger random crashes or reboot loops.
Step 4: Test RAM for Errors Before Continuing Installation
Faulty or unstable RAM is a major cause of installation crashes. Windows setup uses memory heavily while unpacking system files, so even small errors can break the process.
If you already have Windows installed, go to Start Menu > Windows Tools > Windows Memory Diagnostic > Restart Now and Check for Problems.
If you cannot access Windows, use a bootable tool like MemTest86 from a USB. Boot from USB using Boot Menu > Select USB Drive > Run Memory Test.
Let the test run for at least one full pass. If errors appear, try removing one RAM stick at a time if you have multiple sticks installed.
Also, ensure RAM sticks are properly seated by powering off the PC, opening the case, and reseating them in the slots.
Stable memory is critical for Windows 11 installation, and fixing RAM issues often resolves repeated crashes immediately.
Step 5: Check and Repair Hard Drive or SSD Errors
A failing or corrupted storage drive can interrupt Windows setup during file extraction, leading to freezing or restart loops.
To check this, boot into Windows installation media and on the setup screen, press Shift + F10 to open Command Prompt.
Type the command:
chkdsk C: /f /r
Then press Enter. This scans and repairs disk errors automatically.
If installing on a new SSD, make sure the drive is properly detected in BIOS under Storage Configuration > SATA/NVMe Information.
If errors are found or the drive is unstable, consider disconnecting other drives and installing Windows only on the primary SSD.
A clean and healthy drive ensures Windows setup can copy system files without interruption or corruption.
Step 6: Update BIOS or UEFI Firmware to the Latest Version
Outdated BIOS versions can cause compatibility issues with Windows 11, especially on newer CPUs or TPM modules.
To update BIOS, visit your motherboard manufacturer’s website and download the latest firmware version for your exact model.
Then copy it to a USB drive formatted as FAT32.
Restart your PC and enter BIOS, then go to Tools > BIOS Update Utility or EZ Flash Tool, depending on your motherboard brand.
Select the BIOS file from the USB and start the update process. Do not turn off the PC during this step.
After the update completes, the BIOS will restart automatically.
Updated firmware improves compatibility with Windows 11 installation and often resolves unexplained crashes during setup.
Step 7: Disconnect All Unnecessary External Devices
Peripheral devices can sometimes interfere with Windows installation, especially older hardware or external storage devices.
Before installing Windows 11, unplug everything except the keyboard, mouse, and installation USB.
Go to Power Off PC > Remove External USB Drives, Printers, External HDDs, and WiFi adapters.
Then restart the installation using only essential devices.
This reduces driver conflicts during setup initialization and ensures Windows focuses only on core hardware.
Many installation crashes are caused by driver conflicts triggered by external devices loading during setup.
Step 8: Try a Different USB Port or Reformat USB Drive
USB port instability can also cause installation crashes. Some ports, especially front panel ones, may not deliver stable power during setup.
Try switching to a rear motherboard USB 2.0 port instead of USB 3.0 or front ports.
If the problem continues, reformat the USB drive using File Explorer > Right Click USB Drive > Format > FAT32 > Quick Format > Start and recreate the installer again.
Also, try a different USB stick if possible. Some low-quality drives fail under continuous read/write load during installation.
A stable installation medium ensures smoother setup without file corruption or sudden restarts.
Step 9: Perform a Clean Install by Deleting Existing Partitions
If previous installations or corrupted system files exist, they can interfere with setup and cause crashes.
Boot into Windows setup and go to Custom Install > Where Do You Want to Install Windows.
Select each partition on the target drive and choose Delete Partition until only unallocated space remains.
Then select Unallocated Space > Next to allow Windows to create fresh partitions automatically.
This removes all corrupted boot records and ensures a clean environment for installation.
Be aware that this step erases all data on the drive, so a backup is required if possible.
