Hi, WORKSTATION2 WORKSTATION2
Welcome to Microsoft Community.
We understand that you are having trouble loading the driver gdrv.sys after installing Win 11 24H2. The gdrv.sys file is a driver file for GIGABYTE motherboards and graphics cards, and if you see the message “Unable to load driver gdrv.sys”, it means that the program is not supported on Windows 11 24H2.If you see the message “Unable to load driver gdrv.sys”, it means that the program is not supported on Windows 11 24H2, it cannot pass the kernel quarantine of Windows Defender, we suggest you to feedback to GIGABYTE's official about the compatibility of this software, due to the working principle of the driver itself and the existence of certain vulnerabilities, it is very easy to be judged as vulnerable. It is very easy to be judged as vulnerable due to the way the driver itself works and the vulnerabilities it has. This needs to be reported back to the manufacturer for them to release a fix for this issue.-If you don't need the program, please uninstall it by going to Control Panel - Programs and Features and find the GIGABYTE program.-If you need to use the program, you can try to turn off Kernel Isolation (Note: Turning off Kernel Isolation is risky, as it may expose your device to unknown programs, so please consider it carefully).1. Search for Windows Security Center in the Start Bar2. Click on Device Security3. Find Kernel Isolation and turn it off.If that doesn't work, you will need to temporarily disable Driver Signing Enforcement:1. Reboot your computer and enter BIOS or UEFI setup by pressing the appropriate key at startup (usually F2, Del, Esc or F10, depending on your motherboard).2. Look for the “Secure Boot” or “Driver Signing” setting and set it to “Disable” or “Warning”. Warning”.3. Save the changes and restart the computer.*Disclaimer: Microsoft provides no assurances and/or warranties, implied or otherwise, and is not responsible for the information you receive from the third-party linked sites or any support related to technology.**If you are going to modify BIOS Settings, please back up all your personal files first to ensure you do not lose data.*Due to the fact that Windows 11 24H2 is still in its early stages of release, some programs may not have been optimized for compatibility, so it is recommended that you contact GIGABYTE after performing the above actions and report the issue to them so that they can issue a fix for the problem.If you have any questions, please feel free to contact us.
