How can I fix PHASE1 INITIALIZATION FAILED BSoD?
1. Make sure your Windows is up to date
Microsoft is constantly working on Windows 10, and if you wish to get the latest Windows 10 features, you’re advised to perform Windows updates regularly.
In addition to the latest features, these updates offer security and bug fixes, and often they fix many hardware and software issues.
So if you’re having problems with the PHASE INITIALIZATION FAILED BSoD error, we advise you to update Windows 10 as soon as you can.
2. Update your drivers
2.1. Perform a manual update
- Press Windows Key + X to open Power User Menu and select Device Manager from the list.
- When the Device Manager opens, locate the driver you want to update, right-click it, and choose Update Driver Software.
- Choose Search automatically for updated driver software and wait for the process to finish.
Drivers are a key component of Windows 10, and if a certain driver isn’t working properly, that can cause the session 1 initialization failed BSoD error to appear.
In order to update a certain driver, you need to visit your hardware manufacturer’s website, find the model of the device you wish to update, and download the latest drivers for it.
Alternatively, you can download all the necessary files by using Device Manager and then follow the steps we mentioned above.
2.2. Update drivers automatically
Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically.
Using an automatic driver updater will certainly save you from the hassle of searching for drivers manually, and it will always keep your system up to date with the latest drivers.
This high-quality software will help you update drivers automatically in just a few seconds and prevent PC damage caused by installing the wrong driver versions.
3. Run the BSOD Troubleshooter

- Select Troubleshoot from the menu on the left.
- Select BSOD from the right pane and click Run the troubleshooter.
- Follow the instructions on the screen to complete the troubleshooter.
Now, we’re going to try Windows 10’s built-in troubleshooting tool. This tool can resolve basically any system-related problem you can think of, including the Windows 10 error, PHASE1 INITIALIZATION FAILED.

- Now, close the Command Prompt and restart your computer.
The SFC scan is another troubleshooting tool we’re going to try here. You can run the SFC scan from the command line, and it also scans your computer for potential flaws and resolves them (if possible).

- When Command Prompt appears, enter the following lines and press Enter after each line in order to run it:

In Command Prompt you should enter the following (but remember to use the letters that match your hard drive partitions on your PC):
- Restart your computer and check if the issue is resolved.
If there’s a problem with your hard drive or partitions, BSOD errors are quite possible. So, we’re going to run a test to see if everything is in its place.
7. Copy Catroot, Catroot2 and CodeIntegrity folders from a working PC
According to the users, PHASE1 INITIALIZATION FAILED BSoD error sometimes appears due to corrupted Catroot, Catroot2, and CodeIntegrity folders.
In order to fix this issue, users are suggesting copying these folders from a working computer and replace them. Before copying these files, make sure that both versions of Windows 10 are identical.
For example, if you’re using a 32-bit version of Windows 10, make sure to copy these folders from another computer that runs a 32-bit version of Windows 10.
8. Temporarily uninstall your antivirus software
In many cases your antivirus can be responsible for the stop code PHASE1 INITIALIZATION FAILED error and in order to fix it, it’s advised that you remove your antivirus software completely.
Removing your antivirus software is relatively simple, but to remove antivirus software completely including all the remaining files and registry keys it’s advised to use dedicated uninstaller tools.
Many antivirus companies offer these tools, and you can download them for free. If uninstalling your antivirus fixes this problem, you can install the latest version of your current antivirus software.
9. Check for problematic software
In some cases, your software can cause this error to appear, especially if you use VPN tools or any similar programs.
If you recently installed or updated certain software, uninstall that software in order to fix this Blue Screen of Death problem.
One of the most efficient methods that allow you to find out exactly what program is causing the Blue Screen of Death error is to access the BSoD file log location.
10. Perform System Restore or reset your PC
- Start the Automatic Repair process by restarting your computer while it boots. (You might have to repeat this step a few times before you access Automatic Repair options.)
- Choose Troubleshoot, select Advanced Options, click System Restore.
- Choose the restore point and follow the instructions.
If the problem is caused by problematic software or a driver, you can fix the PHASE1 INITIALIZATION FAILED BSoD error by performing a System Restore.
- Start Automatic Repair.
- Choose Troubleshoot then Reset your PC.
- Select Remove everything, choose Only the drive where Windows 10 is installed.
- Follow the process and wait for Windows 10 to install again.
If the System Restore didn’t fix the problem, you need to reset your PC. Before we start, we urge you to back up all your important files since this process will remove all files and folders from your C drive.
By performing this process you successfully deleted all files and folders from drive C thus removing any potential software problems.
If the error PHASE1 INITIALIZATION FAILED still appears, it’s most likely that it’s being caused by a hardware problem.
11. Check your hardware
If you recently installed any new hardware, make sure to replace it or remove it since it might not be fully compatible with your PC.
If no new hardware is installed, make sure to check your hard drive and RAM since they are the most likely causes of PHASE1 INITIALIZATION FAILED errors.
To check your RAM you can use tools such as MemTest86+, just make sure to keep the tool running for a couple of hours in order to perform a thorough scan.
If your RAM is working properly, the error is probably caused by another component. Users reported that your hard drive can also cause this error, so make sure to replace it.
