[Fixed] “Installation Failed in the safe_OS Phase” Error
What Is the Safe OS Phase?
The operating system encounters an error while updating, whether online or offline when it cannot migrate the driver due to the risk of unauthorized operation. During the safe OS phase, the system verifies that all components, including drivers, function according to their intended programming.
To maintain system reliability, all operations must be appropriately encrypted and signed. Attempting to force an incompatible upgrade can often result in a blue screen of death (BSOD).
What Is the Prepare-First-Boot Operation?
During the First Boot operation, a computer can load its operating system from various sources, such as its internal or external hard disk or pen drive that may be connected to it. This allows for flexibility in how the computer starts up.
The BIOS settings can be adjusted to modify the order in which the computer searches for the operating system during the First Boot operation. This can be useful when the primary operating system has become corrupted or damaged and an alternate operating system needs to be loaded from an external source.
Fix Windows Installation Failed in Safe OS Phase With an Error
It’s common to encounter errors when using a computer, but the good news is that they can usually be resolved quickly. This guide outlines methods to tackle a specific error and provides possible reasons and solutions to help make future troubleshooting easier. Each technique presented applies to this error.
Identifying the exact cause of the error can confuse users, as there can be multiple underlying reasons.
