Updated today, unable to boot, refer to BIOS.

Hi, I had something similar happen- not to 2004, but a different feature update, as I'm staying with 1903 for a couple of reasons for now.

Exactly the same- except I'd left it overnight- had to force shut down. And as you say it recovered.

What I then did was, using my downloaded iso file, to reattempt the upgrade but without accepting updates as part of the upgrade procedure. Indeed, you can simply disconnect the internet. This succeeded in the expected time, and updates were applied subsequently.

However, in your case, it sounds as if the upgrade or update succeeded.

The forum prompted you to state your current build number (so we don't keep having to).

Please could you do so to confirm what happened:
win key + r, winver

You may see or check your build numbers here:

- and also search that thread for yours.

Thanks for replying, I am not with the PC now, but I usually screenprint and save the updates as the new version appears, has to that, will post it. The other day I had the WAAS problem which had to do with updating, so on further thoughts I may have switched off the PC then before it was completely fully shuttted down, I rarely do that, but if I do its funny on next startup .

Note: What I experienced in the past over all the problematic updates hanging at a certain percentage, was that if I just pull the DSL cable to PC for 1 minute and reconnect, it then always completed the update, so I used that successfully in the past.
