Fix Error Code 0x800701E3 on Windows 11/10 during Windows Setup

While a Windows 11/10 upgrade is going on, a number of components take part in this process. There is the Network, CPU, Disk, and even more. Thus, it makes the process of upgrading Windows intensive. However, if there is an obstruction in your upgrade process, you could end up seeing error code 0x800701E3. This is caused mainly due to the ‘disk’ part of this whole process. It is caused due to a conflict with the storage of the computer.

Windows cannot install required files. Make sure all files required for installation are available, and restart the installation. Error code: 0x800701e3.

Today, we will be discussing how to fix error 0x800701E3 during Windows 10 Setup.

Error code 0x800701E3 during Windows Setup

To resolve this error code 0x800701E3, we will be carrying out the following fixes:

1. Delete System Files related to both the components.
2. Use System File Checker and DISM.
3. Use CHKDSK.

Exit the setup process and boot normally into your Windows.

1] Delete System Files related to both the components

Some residual junk system files like Cache files and driver residue can block an upgrade. Hence, I would recommend you to run Disk Cleanup to delete the files and data that is safe to be removed from your computer. The main files that you need to remove here should be Previous Windows Installations.

You can also use third-party software like CCleaner to clean up System and Registry junk that might be causing a conflict.

2] Use System File Checker and DISM

Run CMD as Administrator and then execute the following command to run System File Checker:

sfc /scannow

Restart your system after the scan is completed.

You can also use our freeware FixWin to Run the System File Checker utility with a click.

Now, to fix Windows Update files using DISM, open Command Prompt (Admin) and enter the following three commands sequentially and one by one and hit Enter:

Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth

Let these DISM commands run and once done, restart your computer and try again.

3] Use CHKDSK

To run ChkDsk, open This PC. Right-click on your Operating System Partition for Windows and select Properties.

Navigate to the tab labeled as Tools. Under the section for Error Checking, click on Check.

A new mini window will now pop up. Click on Scan drive.

Let it scan your disk drive partition and after that reboot your computer for the changes to take effect.

Having done this, try running Setup again.
