I have been on the Win 10 fast track with four computers since the start. All upgrades have been successful until 10240 fails to upgrade on my Lenovo Yoga 2 laptop. It gets to about 19 percent and then reverts back to build 10166. I noticed a safe mode indication during the upgrade and I don't know if that is significant. Two of my computers have been successfully upgraded to 10240. I haven't tried 240 on my other Lenovo laptop yet.
Yoga has got to be the worst name for a compter, ever.
It beats Apple..
Heh.
Yoga Berra wouldn't think so.
The upgrade finally finished successfully after an insane number of attempts.
It's Yogi
Yogi Berra is one of my all time favorite players. He hit home runs off balls that were thrown at his ear.
After about 20 upgrade attempts, the new build (rtm?) was upgraded. I did nothing but keep trying to get the upgrade many times, when much to my surprise the upgrade finally succeeded. I can't take credit for anything more than patience and persistence.
The force is strong with this one
