💡 Why You Are Getting This Error

  • The primary reason for this error is that the firmware's reserved region on your HP Notebook 15-ac101tu is not compatible with the UEFI-based installation of Ubuntu 20.

🚀 How to Resolve This Issue

Updating BIOS to fix UEFI compatibility

  3. Step 3: Save changes and exit the UEFI settings utility. Then, plug in the USB drive containing the Ubuntu installation media and attempt the installation again.

Using a different installation method

  1. Step 1: Try installing Ubuntu using a different installation method, such as a Live USB or a CD/DVD. This may help bypass any issues with the UEFI firmware.
  2. Step 2: Create a Live USB drive using Rufus software and attempt the installation again. If this fails, try using a different Linux distribution that supports UEFI boot.

🎯 Final Words
