    What causes "Windows 8.1 installation has failed"?

    I have 3 computers, all running Windows 8 with no problems. I could not update to Windows 8.1 on any of them using the Store. Just kept repeating the download over and over with never running the installation. I was able to update to 8.1 on 2 of the computers using the ISO/DVD method as described in several places on the forum. This went smoothly. On the third computer, installation seemed to be working (went past the 100% mark), then suddenly popped up the message "Windows 8.1 installation has failed" and the installation abruptly halted. There was no explanation or error code. My question is: what causes this message? There must be a way to determine what triggers it so the problem can be corrected. I can find no log file or other clue. Maybe I don't know where to look. If anyone has the solution to this annoying problem, please let me know.

    Thanks,
    Jarome

    You could try the setup logs to see if there is anything there that may shed some light on what is happening: http://technet.microsoft.com/en-us/l.../hh824819.aspx

    I suspect it's some kind of hardware issue. It could be a CPU compatibility. I would also see if perhaps there is a Bios update for the failed PC.

    Here is what I have tried: Downloaded the latest BIOS. No difference. Ran chkdsk.exe, sfc /scannow and WMD (windows memory diagnostic). Found nothing. Decided to do a REFRESH to replace any corrupted or missing system files. It started, but then stopped with the error 0xc000000e - "A required device isn't connected or can't be accessed". Then I decided to start from scratch and reinstall Windows 8 from the installation disc. It got to about the same place that Windows 8.1 failed and displayed the exact same message: "Windows 8 installation has failed" and would not let me reinstall Windows 8. I think it must be a basic hardware problem but I have no idea of how to find it. Does anyone know of a good diagnostic tool that might help? Right now I am running Malwarebytes in case it could be a virus or other malware. I will post the results.

    Thanks,

    Did you check your Device Manager?

    Device Manager shows no errors. Downloaded memtest86 and running it now. Has been running for 15 minutes and shows no memory errors so far. Will let it run to completion. Thanks for alerting me to it. Looks like a good utility. Still looking for the solution. I did try boot mode set to "legacy". It was set to "UEFI and Legacy" in the BIOS setup. Made no difference.

    Thanks,

    Did you check the setup logs? That's the certain way to find out. Windows logs pretty much everything it does, precisely because of situations such as this.
