If you don’t have an installation media, you can create your own with the help of this guide (for Windows 7) or this guide (for Windows 10). To learn how to boot from the media, please check this article.

Method 1: Undo the recent changes

If you have changed the settings or turned on a feature on your computer, and the BSOD occurred right after, it is likely that the changes are the cause. You should undo those changes. Then check to see if your blue screen error is gone. 

It is also possible that the error occurs after you install new software or hardware. If so, uninstall those programs or devices and see if this fixes your error.

NOTE: If the steps above fix your NETIO.SYS blue screen error, you should contact Microsoft support, the vendor of your program or the manufacturer of your hardware and ask them for advice.

You can also use the System Restore feature to restore your system to a previous state. This will help you undo the recent changes and fix your blue screen error. To do this:

1) Click the Start button at the lower left of your screen. Then type “recovery“. After that click Recovery in the list of results.
