I tried all the options when offered at boot time of Win 10, and none seem to work, Two weeks ago i successfully updated it to the 21h version, and now for some reason i cannot get into win 10. I even tried the MBR fix and it failed. I do have the iso file that i used to update win 10, 2 weeks ago on my thumb drive, but can't find a way to use it with win 10 unapproachable. Just to note that my version is all from updates, no disc. Suggestions would be appreciated if I had not tried them as yet.
