Operating system boot mode change (021) | **** + enter - to complete the change

Hi Guys, Learn how to fix "Operating system boot mode change".

The Boot Menu allows a user to load up other operating systems or applications, even if the computer itself already has an operating system on it. A Boot Menu is also useful for installing a new operating system on a computer because the user can choose what device to use.

Your system is equipped with UEFI BIOS, which is based on the Unified Extensible Firmware Interface (UEFI) specification. For this reason, the system can be configured to boot in Legacy BIOS Boot Mode or UEFI Boot Mode. Legacy BIOS Boot Mode is the default.

To access your BIOS, Press F2 to access BIOS, Press DEL to enter setup
