    How to solve "The Installation Failed in the Second Boot Phase" 0X8007042B - 0X4000D


    I've been trying to upgrade from Windows 10 to Windows 11 for over a month now. Each time I get an error message stating that the Installation Failed in the Second Boot Phase. I've tried upgrade via the upgrade exe file that you can get from microsoft, and through a Windows 11 installation media file that I created.I've also tried removing all excess/old drivers and ensuring that all of my drivers, and my BIOS are up to date. I've tried enabling and disabling secure boot, unplugging everything except my mouse, hard drives, and an aRGB controller that is pretty difficult to get to.I also made s

    Windows 10 Upgrade failed - 0x8007042B - 0x4000D failed in the second boot phase with an error in the migrate_data option

    Hello,

    I am trying since weeks to upgrade my HP EliteBook x360 1040 G5 to the latest Windows 10 version without so far any success.

    Windows 10 Pro, version 1803, installed 27/02/2019, OS Build 17134.1345.

    I have 70 GB free and last time the update went to 92% before getting "0x8007042B -
    0x4000D failed in the second boot phase with an error in the migrate_data option".

    I have tried all the tips i found on internet but none worked.

    Any ideas?

    Hi Dhiraj. I'm Greg, here to help you with this.

    1) Here are fixes for the 0x8007042b-0x4000d Upgrade failure:

    https://www.howto-connect.com/fix-windows-10-er...

    https://www.howtoedge.com/fix-error-0x8007042b-...

    https://www.partitionwizard.com/partitionmanage...



    2) Update your drivers and BIOS/UEFI firmware from the PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start button. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

    Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page. Everything else depends on this.

    3) Follow the steps under Download Windows 11 DIsk Image ISO, by clicking the link "Before you Start" at https://www.microsoft.com/en-in/software-downlo....

    4) Double click ISO to mount it as a virtual drive, right click Setup to Run as Administrator, follow steps here to Upgrade from ISO:

    https://www.thewindowsclub.com/clean-install-or...

    5 If failure persists post a screenshot of Disk Management, which I read like a doctor reads X-rays. Follow the steps here so I can see everything needed to advise you: http://answers.microsoft.com/en-us/windows/foru...

    6) You can also do a Clean Install which is a superior install anyway:

    https://www.windowscentral.com/how-do-clean-ins...

    Create bootable WIndows 11 media by following the steps under Create Installation Media, clicking the link "Before you Start" at https://www.microsoft.com/en-in/software-downlo....

    Make sure during the booted install to unplug all other drives, boot the media as a UEFI Device, choose Custom Install, delete all partitions down to Unallocated Space to get it cleanest, choose the Unallocated Space, click Next to auto-create and -format the needed partitions and begin install - this makes it foolproof.

    After install (even for the Upgrade) expedite all Windows Updates including Optional until no more are offered. Then import any drivers from the PC maker's Support Downloads web page for your model that are newer, or branded instead of generic. The most basic thing we need to learn to maintain a PC is how to keep the latest manufacturer's drivers current. Windows drivers are rarely enough.

    Please report back results for each step in every link, so I know what else to suggest. I will keep working with you until it's resolved.

    How to solve "The Installation Failed in the Second Boot Phase" 0X8007042B - 0X4000D

    Win 10 Anniv fail - 0x8007042B - 0x4000D AND rasadhlp.dll


    just started to research this...

    0x8007042B - 0x4000D failed in the second boot phase with an error in the migrate_data option

    the worst part is, the restore messed up my computer ... have an error with windows\system32\rasadhlp.dll file and the online help doesn't repair it.

    should i try to get the update to work and hope that fixes the dll problem?

    i'm gonna do a clean boot and reinstall it and see if that works.

    ... and it worked. I forgot the clean boot upgrade/update trick til I saw it... I had to do it to upgrade from 7 to 10.
