How to Open Device Manager During Installation of Windows 8 and 8.1


information   Information
This tutorial will show you how to open Device Manager and disable trouble devices during the installation of Windows 8 or 8.1.

This can help solve problems during installation such as hanging and crashing due to a problem device.

For example: If your graphics card is what's causing the issue, then you could disable it in Device Manager during installation to causeWindows to use the default 'Standard VGA Adapter'. Once you have finished the installation and booted to your desktop, you could then download and install the latest video drivers to have your graphics card work properly afterwards.




Here's How:

1. Boot from your retail Windows 8/8.1 installation DVD/USB, and do the usual steps 1 to 9 in either tutorial link below while installing Windows.
2. When installation is ready to do it's first restart, wait or click/tap on Restart now, and boot from the Windows 8/8.1 installation DVD/USB again. (see screenshot below)

warning   Warning
It's important that you boot from your Windows installation media again after restarting, and do not let the installation setup continue for now.

bcdedit /set {default} safeboot minimal


6. Restart the computer to boot into safe mode.


7. When the computer restarts, you will get a warning that "Windows cannot complete installation in Safe Mode...". (see screenshot below)

bcdedit /deletevalue {current} safeboot

13. Close the command prompt, and click on OK for the warning to restart the computer and continue the installation. (see screenshots below steps 7 and 8 above)

14. If you disabled the correct problem device, then installation setup will hopefully continue until Windows 8 or 8.1 is finished installing. If not, then repeat this tutorial until you disable the correct problem device.
