    8.1 Upgrade fails, Error Code 0x800703f9

    On an Asus laptop with Windows 8 preinstalled, I have secure boot on, AV off, but every time I try to install the update from the Windows Store I get as far as:
    Getting the update ready
    This App wasn't installed, - view details.
    Something happened and the Windows 8.1 couldn't be installed. Please try again. Error code 0x800703f9

    I've tried installing with nearly every non-windows process disabled, but that doesn't help. I've Googled the error number, but although I found instances of it (back to Vista), I couldn't find what the error was or anything helpful.

    I've also experienced this issue. I know that on my system I managed to partially break the Windows bootloader and I've assumed that's the source of the problem, having tried a lot of other potential resolutions that haven't worked. I've tried repairing the bootloader without success so I think it's going to take a "refresh" or reinstall to solve. I don't have time to do that at the moment though so I can't confirm that that will work (I may not do it in the near term anyway because I don't trust it not to nuke the dual booting Linux partition on the same disk... which is how I managed to damage my bootloader in the first place :P)

    Try the drivers provided by the manufacturers and see whether it helps, from this post by theog:

    Thanks for the reply. Unfortunately HP's site simply says my laptop is not tested with Windows 8.1.
