I have just upgraded my motherboard and CPU to ASUS ROG STRIX Z490-E Gaming + i9-10900 S. My old motherboard and CPU were EVGA X99 classified and i7-5930K. The reason for upgrade was that my PC wouldn't boot up 5 days ago. After numerous emails to EVGA technical and EVGA forum. Prior to that I actually replaced the PSU and memory modules. To cut a long story short, after installing the new motherboard and CPU, the system booted up to the BIOS whereas I couldn't do that with the previous motherboard and CPU. I only changed the Secure Boot setting from "Other OS" to "Window UEFI Mode". In previous system, I have 1 x 2TB SSD as boot drive. 1 x 1TB as Game drive, 1 x 3 TB WD black as data drive and 1 x 6 TB WD Black as backup drive. Oh, and a LG Bluray writer. These are all detected by the new motherboard.
When I restarted the system, a message saying, "The system found unauthorized changes on the firmware, operating system or UEFI drivers. Press [OK] to run the next boot device, or enter directly to BIOS Setup if there are no other boot devices installed. Go to BIOS Setup > BOOT and change the current boot device into other secured boot devices." There is no other bootable device. Window 7 Ultimate Pro 64 bit was installed on the 2TB SSD. Although it was quite some time ago, I distinctly remembered that UEFI was selected. If anyone can help, it would be greatly appreciated. Many thanks in advance.
