Installing Windows on a new computer or upgrading an existing computer usually goes without errors. Some Windows users have reported an error code 0x8030002F when upgrading/installing Windows 11 on their computers. If you try to install a modified version of Windows (anything other than the original version of Windows), Windows will stop the installation and give you an error message.
What causes the error code 0x8030002F?
- The installation media is a modified version of Windows: the most common cause of this error is when a user tries to update to the latest version using a modified version of the Windows installation media.
- Damaged HDD/SSD sectors: It turns out that corrupted system files can also cause this error if the corruption involves MBR or BCD files used in the update process.
- Damaged boot configuration data: If you only see this error when trying to upgrade your version of Windows to the latest version, you should try running a series of augmented CMD commands to prepare your boot configuration data.
- Damaged system file: In some cases, a corrupted system file may cause this error when trying to upgrade to the latest version of Windows.
