    A100TA - cycles booting in Recovery mode

    Here's the best four letter word : HELP
    My daughter has had her T100TA for 1.5 years. No issues. works great.
    Then last week Microsoft released some updates. After she agreed to install them, the computer rebooted.
    Now it goes into Recover mode stating Your PC couldnt start properly. A required device isnt connected or cant be accessed. Error code 0xc0000185. You need to use the recovery tools on your installation media. If you dont have it contact your system admin or pc manufacturer.

    I called Asus. They said I'd have to send it in for repair. I asked how much and was quoted $450 Canadian (which is almost double what I paid for it from Best Buy)

    So, I thought maybe just to reformat the memory and reinstall with windows 10. I prepared a Windows 10 bootable USB key, told the tablet to boot from it within the BIOS. On reboot, I get the windows 10 splash window with the rotating circle and then it says the same thing.

    I tried booting without the Boot Manager and got IMAG1296.jpgIMAG1295.jpga DOS-like window with the same error but further details:
    File: \EFI\Microsoft\Boot\BCD
    Error: 0xc0000185
    Boot configuration data for your PC is missing or contains errors.

    So, how can I boot from the USB key to get to format the memory and reinstall windows?

    Any ideas out there would greatly appreciated. I dont want to brick this nice tablet.

    Welcome to the forum

    Sorry, but I'm no Windows expert - won't use the OS any more. However, isn't there a safe mode you can boot into? What happens when you press f2 to get into recovery during the boot cycle?

    I'm sure someone with more current Windows experience than I have (not difficult ) will be along soon...

    Your opinion matters. But should you disagree - please try not to be disagreeable

    The trick will be to get into the command prompt from the recovery environment. What happens if you press F9 while booting to get into the Asus recovery console? Then you can try some of these fixes:

    You can also try to boot from a USB ISO created by the media creation tool:

    It could also be BIOS setting, disabling Disable Hybrid Graphics will usually fix it:

    Otherwise, I'd agree, could simply be a procedure issue. From the setup menu, you should be able to run a repair installation, if the USB drive is setup correctly.
