This approach can help you determine whether non-Microsoft products triggered the IO1_INITIALIZATION_FAILED problem. Here are the steps you can take to do a clean boot:

  • Type Windows + R to bring up the Run box.
  • Press Enter after typing msconfig.
  • Services > Hide all Microsoft Services > Turn off all of them > Startup.
  • On the next screen, click Open Task Manager. Then, select all services and goods that Microsoft doesn’t make and click Disable.
  • Last, on the Startup tab, click OK.

Take note: If the mistake still doesn’t go away after trying all of these things, it’s different from the usual options, basic device drivers, or Microsoft goods. That’s why you should use the Advanced ways.

Before you move on…

Before you try more complicated repair steps, you should use powerful data recovery software like Stellar Data Recovery Professional to get back your data from the machine that had a BSoD. There is a choice in the program to “Create recovery media.” It lets you make a portable media drive that you can use to get back data from a machine that won’t start up, has crashed, or has a blue screen.

Advanced Troubleshooting Methods

To do these fixes, go to WinRE (Windows recovery environment), which helps fix O.S. that won’t start up or has crashed.

Hold down the power button for 10 seconds to turn off your system. To turn it back on, press and hold the power button again.

  • As soon as Windows starts up, press and hold the power button for another 10 seconds.
  • Start the machine up again. Do the same things three times, and then let your machine fully start up.
  • You’d get to WinRE. Follow the steps given once you’re in the Windows Recovery Environment.

Solution 4. Run Startup Repair

Auto Repair is the name of the page you’d see in WinRE. There, click on More Choices.

  • On the screen that says “Choose an option,” choose “Troubleshoot.”
  • Now, click on Advanced Choices once more.
  • After that, choose Startup Repair from the list of choices.

Allow the process to go. After it’s done, restart the computer and see if the problem is gone.

Solution 5. Rebuild MBR

System MBR issues might potentially cause the error. Here are some steps you can take to fix it:

  • To get to the Command Prompt in WinRE, go to Advanced Options> Troubleshoot > Advanced Options> Command Prompt.
  • Type each of the following orders one at a time in the higher cmd window, then press Enter.

bootrec /fixMBR

bootrec /fixBoot

bootrec /rebuildBCD

  • Start up your system again and check to see if everything is okay.

Solution 6. Run C.H.K.D.S.K. Command

Another thing you can do is see if there is any damage to your hard drive. Broken or damaged hard drives might cause IO1 Initialization Error. To do this, take these steps to run the C.H.K.D.S.K. command:

  • Go to Advanced options > Troubleshoot > Advanced options > Command Prompt in WinRE.
  • After that, type chkdsk /f /r D: and press Enter. (Instead of D, type the letter of your hard drive.)

It’s time to see if the problem is fixed. Close the cmd window and start your system up again.

Solution 7. Set Disk Controller mode

Your computer may have the wrong drivers or A.H.C.I. or RAID mode on your Disk Controller. Your computer may display the Windows halt code IO1 INITIALIZATION FAILED. In the BIOS setup, you need to change the Disk Controller to either SATA or A.T.A. to get rid of this problem.

Follow the steps in the user manual that came with your computer to get into BIOS and then change the Disk Controller mode properly.


Q1. What does system initialization mean?

System setup is the process of finding and using the set settings for a system program’s variable data. For instance, an O.S. or app is loaded with values chosen by the user, which further determines how the app or system will work.

Q2. What are the common reasons for the IO1 initialization failed Windows 10 error?

This BSoD problem usually happens because of device drivers that need to be compatible, are out of date, or are damaged. Other causes include missing or damaged system files, third-party apps or programs that aren’t compatible, MBR corruption, or a hard drive that isn’t working right.

Q3. Can RAM also cause an IO1 Initialization Error?

An IO1_INITIALIZATION_FAILED error or another blue screen error could be caused by RAM that is broken or old. When you want to see if your RAM is broken, you can use the Windows Memory Diagnostic tool or memtest86.

Q4. There is a lot of data on my laptop. I want to recover that before fixing the IO1 INITIALIZATION ERROR. Can I do it?

Because it’s a blue screen mistake, you might not be able to get to your machine or its files. Because of this, we suggest that you use strong data recovery software like Stellar Data Recovery Professional. It has a bootable media recovery tool that lets you get back data from a laptop that won’t boot or has a BSoD.


Okay, this is the end of my piece. I have done my best to give you the right answers and details about the IO1 Initialization Failed Windows 10 Error.

Try each fix one at a time and see which one works best to fix the error and get rid of the B.S.O.D. error on your P.C. If you don’t want to use the instructions, you can also use the simple method given above.
