Thanks for your messages, michael_anderson. I'm glad you were finally able to install the 22H2 update with no issues. As you see from my original message - I was also able to install 22H2 - by disabling the Secure Boot in the Bios. However, I'd like to be able to enable the secure boot again, without running into problems. I am concerned about the vulnerability to security, privacy and malware. But, every time I enable secure boot - I get the blue screen: inaccessible boot device. This is my main concern.
