Hey I Upgrade to windows 11 approximately one month above and when I started it some black arrow error was coming like all the the other version of windows at startup. Then after some time it was asking me for recovery and was sayin' "Your PC Did not Start Correctly" and giving me two option to continue 1. "advance data recovery" and "reset" and I think that reset actually means factory reset and like you'll I would like to choose advance data recovery option and was showing many options such as troubleshoot, command prompt, start up settings, and and recovery and under that recovery option was only one option that was to go back to windows 10 and I selected that. Then it started and took some time and was loading, then it made me get back to windows 11 again and no OS was changed by doing so windows please fix this error it's 2021! and one more thing that, in windows 11 why always that Cortona pops up in middle whenever I do my work. Please fix these 2 problems if possible team Microsoft and Windows.
