“It said something about a bios being updated, I waited like five minutes but nothing changed, so I restarted the pc.”,(reply>), I'm much more comfortable when there's a working recovery mechanism. Worst case a full dump of the memory chip. I've recovered a failed firmware update by desoldering the chip and flashing it externally with a previous backup image. It's a real PITA but at least I didn't need to replace the motherboard.,(reply>), @stonecat Yep... that sort of thing can happen -- which is one of the reasons why most folks who have been around PCs long enough will be quite hesitant to perform firmware update and tend to speak of the "in a flash the ROM is gone!"   If we do install the update (if there's no other alternative) we take every precaution possible (i.e. be paranoid about it) to avoid any sort of problem (e.g. avoiding performing update form online source -- you could get disconnected in the middle -- better to download the complete image and put on local storage), also making sure we plug everything involved into UPS (to avoid problem that might occur if we get "brownout" or complete power failure during the process).,(reply>), @Sara Vin You just wait. I had to reinstall Windows recently and the progress bar stayed on 80% for probably 10 minutes. Apparently people have had similar situations for several hours. If you give it enough time it'll eventually get done though.,(reply>), @Naoto Kimura I hard bricked an old phone because the shitty cable unplugged on its own<br>so much pain...,(reply>), Windows once did some updates and told me not the restart right now. But nothing happened for several minutes. I'm not sure what people expect to do when a PC seems to be stuck on a critical update where you shouldn't shutdown the PC. It's the last thing you can do. Luckily for me the PC still worked after.
