I was setting up a seccond windows 10 drive and, it worked, then when i went to boot to my older drive, the os loaded i could log in, but the desktop bg wasn’t what i set it to originally it was set to black, and it wouldn’t let me access my own files, and the only software that works is settings, windows run, command prompt, task manager, and all my task bar icons are gone, and it says there is a problem with the task bar and to sign out so it can try to fix it, my attempts were futile, anyone know what happend
