Resolving the “Boot Device Not Found” Error Caused by Disabling Intel Rapid Storage Technology on HP Pavilion Convertible Laptop

Introduction

Encountering a “Boot Device Not Found” error can be a frustrating experience, especially when it occurs unexpectedly after disabling important system drivers or services. In this article, we will discuss how disabling Intel Rapid Storage Technology (IRST) can impact your laptop’s boot process and provide step-by-step guidance on how to re-enable it, focusing on an HP Pavilion Convertible laptop model.

Understanding Intel Rapid Storage Technology

Intel Rapid Storage Technology is a driver and firmware suite that optimizes the performance and reliability of systems with SATA or NVMe drives. It manages how data is stored and accessed on your disk drives, and disabling it may lead to boot issues, especially if your system relies on the driver for recognizing boot devices.

The Issue: Disabling IRST and Its Effect

Disabling IRST can interrupt the system’s ability to recognize your operating system drive during startup, resulting in an error message like “Boot Device Not Found.” This can occur if the system was configured to rely on IRST for drive management or RAID configurations.

Step-by-Step Solution to Re-enable Intel Rapid Storage Technology

Access the BIOS/UEFI Settings
Shut down your HP Pavilion Convertible laptop completely.
Turn it on and immediately press the Esc key repeatedly (or the F10 key for HP systems) to access the startup menu.
Select BIOS Setup or UEFI Firmware Settings from the menu.
Locate Storage Configuration Settings
Within the BIOS/UEFI menu, navigate to the Storage or Advanced tab.
Find the SATA Configuration or similar option.
Re-enable Intel Rapid Storage Technology
Look for settings related to SATA Mode or RAID Configuration.
If it is set to AHCI, switch it to RAID if your system originally used RAID mode with IRST enabled.
Alternatively, if the setting was simply disabled, enable it back or set the SATA Mode to Intel RST or RAID.
Save the changes before exiting (usually by pressing F10).
Re-enable the IRST Driver in Windows (if accessible)
Boot into Windows if possible.
