Something happened, Windows 10 installation has failed error.

Entropy said:

I have downloaded the tool from here https://www.microsoft.com/en-us/soft...load/windows10 (64-bit) and I get the infamous message of "something happened" the moment I have made all my choices and the download should start.
I’ve chosen to create a USB media but I get the error also with ISO
I’ve seen online that a possible cause was the regional settings, which is not the case with me.
I run windows 8.1 PRO.

Does anybody know anything?

I tried running the Media Creation Tool X64 multiple times, and it does nothing...no error messages, no setup screen, no "Something happened"...nada, zilch, nothing at all. Any ideas?

I found a solution and I think it might work for you too since you problem seems very similar. It turns out that there was some problem with the boot configuration data and I simply had to rebuild it. I found good instruction of how to do it here - https://www.winhelp.us/repair-your-c...8.html#bootrec - look for "Step 1.3 (optional) - repair Boot Configuration Data". More clear and straight forward instructions can be found here http://pcsupport.about.com/od/fixthe...re-windows.htm , but they only work for legacy boot mode, if you have UEFI boot mode you will need to use following commands instead:


diskpart (opens Disk Partitioning tool)
select disk 0
list volume (please note the number of the volume that has no drive letter assigned and has FAT32 listed in Fs column)
select volume <the number of ~500 MB FAT32 volume with no drive letter, or with label ESP>
assign letter=Z: (gives drive letter Z: to EFI System Partition)
exit (closes Disk Partitioning tool)
cd /d Z:\EFI\Microsoft\Boot\ (changes current folder in Command Prompt window)
attrib Z:\EFI\Microsoft\Boot\BCD -h -r -s (removes hidden, read-only and system attributes from BCD folder)
ren Z:\EFI\Microsoft\Boot\BCD BCD.old (renames BCD folder to BCD.old)
bootrec /rebuildbcd (retries the rebuild)

I can verify that this advice solved the failure at 24%. It was the boot record causing the problem. Many thanks.

Hey Guys, can i just check that you've tried redownloading the installation files?

The Microsoft KB points to these errors being caused by corrupt/missing files within the installation directory.

Hi Sniper, you know i had problems with the upgrade for my 4th computer, since you tried to help me with that.

After trying to upgrade some 7 times, i tried to find a solution for the problem on the net, but also gave feedback to Microsoft, without a reply, but i guess they have enough work right now.

Finally i looked here on the board and found what i quotes above.

And it works also for my problem....very strange .... only one command to do.

Right now installation is busy and should end in half an hour or so.

Kudos to you and thanks

Jeff

I found myself the solution after 2 days of searching the Internet, however, I believe that this error is not the same for everybody.

My Internet connection, A1 mobile Internet here in Austria, had firewall and antivirus on my connection without my knowledge.
The moment I disabled these services from my online account with my internet provider everything works now as expected without problems or stupid messages like “something happened” that I received when I was trying to download the ISO of windows 10…

The firewall & antivirus of my provider prevented the download.

That’s it..

This also worked for me. I was upgrading from 8.1 to 10. I tried different ways others suggested and none of them worked (always failed at around 24%). After rebuilding the Boot Configuration Data, windows 10 installed successfully. I am now running win 10. Thanks so much, cifad.
