让我们了解如何在下面提到的解决方案的帮助下修复第一个引导阶段错误中的安装失败。

检查你的磁盘空间
禁用/卸载第三方防病毒应用程序
断开所有外部硬件
执行干净启动，然后尝试
在日志文件中搜索。

让我们更详细地了解所有这些解决方案。

1]检查您的磁盘空间

如果您尝试在磁盘空间不足的驱动器中安装Windows ，安装将失败。^(Windows)在执行Windows^(Windows)升级之前，我们必须检查硬盘上的可用磁盘空间。您的系统上至少应该有 30 GB 的可用空间。

您可以按照以下步骤检查系统上的可用磁盘空间：

按“ Win + E ”键打开文件资源管理器^{(File Explorer)}窗口。
在左侧窗格中，单击“此 PC”^{(This PC’)}（或 <您的计算机名称>）。
您现在可以查看要安装/升级Windows 11/10的驱动器。

如果驱动器至少有 30 GB 的可用空间，则可以安全地开始安装。如果驱动器空间不足，您需要通过删除或移动某些文件夹来释放一些空间。

2]Disable/Uninstall第三方防病毒应用程序

第三方防病毒软件应用程序可能是您在计算机系统上安装/升级Windows期间遇到的错误 800704B8 – 0x3001A 的原因。^(Windows)您应该尝试暂时禁用该应用程序或完全卸载该软件。有时，第三方安全软件可能会干扰该过程并可能导致此错误。

您可以按照以下步骤操作：

右键单击^{(Right-click)}系统托盘中的第三方防病毒程序^{(Antivirus Program)}图标。
从上下文菜单选项中，选择“禁用^(Disable)”或“暂停保护^{(Pause Protection)}”。
现在选择您希望防病毒软件^(Antivirus)保持禁用的时间范围。

成功禁用后，再次尝试执行安装过程，看看错误是否解决。

3]断开所有外部硬件

要解决此错误，请尝试断开连接到系统的所有不必要的外部设备。请注意，这不包括您的鼠标、键盘和显示器，因为这些对系统至关重要。

4]执行干净启动

使用以下步骤在Windows 10中执行干净启动。

您首先需要以管理员身份登录系统。
现在，在任务栏的搜索框中键入“ msconfig” ，然后从搜索结果中选择^{(msconfig’)}系统配置^{(System Configuration)}。
在“系统配置^{(System Configuration)}”窗口中，单击“服务^(Services)”选项卡，然后选择“隐藏所有 Microsoft 服务^{(Hide all Microsoft services)}”。
一旦选择点击“全部禁用^{(Disable all)}”。
现在单击“系统配置^{(System Configuration)}”窗口的“启动”^(Startup’)选项卡，然后选择“打开任务管理器^{(Open Task Manager)}”。
“任务管理器^{(Task Manager)}”窗口打开后，单击每个启动项，然后选择“禁用”^(Disable’)。
现在，关闭“任务管理器”并在“^{(Task Manager’)}系统配置^{(System Configuration)}”的“启动^(Startup)”选项卡上选择“确定^(OK)”。

注意^(Note)– 如果您没有管理员帐户，则必须创建一个。使用本指南创建管理员帐户。

现在，当您重新启动系统时，它处于干净启动状态^{(clean boot state)}。现在试试看你是否成功。

5]在日志文件中搜索

这是您可以做的另一件事，查找可能被命名为“xxxxxxx_APPRAISER_HumanReadable.xml、setuperr.log 和 setupact.log”的安装错误日志文件^{(Setup Error)}

如果有任何与磁盘空间相关的实例，请在这些日志中搜索。它可能类似于“ DISKSPACEQUERY : Final disk space required estimate”。

如果是这种情况，则更新需要硬盘驱动器上的更多空间来完成安装。

If you trying to upgrade to Windowѕ 10 or upgrading to a new update from Mіcrosoft, then there may be occasions where the installation may fail leaving you with error 0x800704B8 – 0x3001A. Microsoft states specific upgrade error codes that start with the digits 0x800 imply general operating system errors. These are not unique to the Windows upgrade process. A few examples include devices not functioning, timeouts, devices not functioning, and a process stopping unexpectedly.

Error 800704B8 - 0x3001A

Windows Boot goes through multiple phases which makes sure that your computer is not compromised. If you get a Windows Update Error Code 0x800704B8 – 0x3001A, it means that there is an extended error has occurred during the first boot phase.

If your upgrade process on Windows failed with an error message stating:

Error 0x800704B8 – 0x3001A
The installation failed in the FIRST_BOOT phase with an error during BEGIN_FIRST_BOOT operation.

In this case, use our troubleshooting guide to quickly fix it.

Windows Update error code 0x800704B8 – 0x3001A

Let us understand how to fix the installation failed in the first boot phase error with the help of the below-mentioned solutions.

Check your disk space
Disable/uninstall third-party antivirus applications
Disconnect all external hardware
Perform a clean boot and then try
Search in Log files.

Let’s look at all these solutions in more detail.

1] Check your disk space

If you are trying to install Windows in a drive having low disk space, the installation will fail. We must check the free disk space on your hard drive before carrying out the Windows upgrade. There should a minimum of 30 GB of free space available on your system.

You can check the free disk space on your system by following the below steps:

Press ‘Win + E’ keys to open the File Explorer window.
On the left pane, click on ‘This PC’ (or < the name of your computer>).
You can now look at the drive you wish to install/upgrade Windows 11/10.

If the drive has a minimum of 30 GB of free space, then it is safe to begin the installation. If the drive is running low at space, you will need to free up some space by deleting or moving some folders.

2] Disable/Uninstall third-party antivirus applications

A third-party antivirus software application can be the cause of the error 800704B8 – 0x3001A that you are facing during the installation/upgrade of Windows on your computer system. You should try temporarily disabling the application or completely uninstalling the software. Sometimes, third-party security software may interfere in the process and may cause this error.

You can follow these steps:

Right-click on the Third-Party Antivirus Program icon from the system tray.
From the context menu options, select ‘Disable’ or ‘Pause Protection’.
Now select the time frame for which you want the Antivirus to remain disabled.

Once successfully disabled, try to carry out the installation process once again and see if the error resolves or not.

3] Disconnect all external hardware

To resolve the error try disconnecting all unnecessary external devices that are connected to your system. Please note this does not include your mouse, keyboard, and display as these are essential for the system.

4] Perform a clean boot

Use the following steps to perform a clean boot in Windows 10.

You will first need to sign into the system as an administrator.
Now, type ‘msconfig’ in the search box on the taskbar and select System Configuration from the search results.
In the ‘System Configuration’ window, click on the ‘Services’ tab, and select ‘Hide all Microsoft services.’
Once selected hit ‘Disable all’.
Now click on the ‘Startup’ tab of System Configuration window and select ‘Open Task Manager’.
Once the ‘Task Manager’ window opens, click on every startup item, and then select ‘Disable’.
Now, close the ‘Task Manager’ and select ‘OK’ on the ‘Startup’ tab of ‘System Configuration’.

Note – If you do not have an administrator account, you will have to create one. Use this guide to create an admin account.

Now when you restart your system, it is in a clean boot state. Now try and see if you meet with success.

5] Search in Log files

Here is another thing you can do, look for Setup Error log files which might be named as “xxxxxxx_APPRAISER_HumanReadable.xml, setuperr.log and setupact.log”

Search in those logs if there are instances of anything related to disk space. It may be similar to “DISKSPACEQUERY: Final disk space needed estimate”.

If that’s the case, the update needs more space on your hard drive to complete the installation.
