Common Issues with Dual-Boot Setups

A dual-boot setup allows you to install and run two operating systems on a single machine. You are prompted to choose one of them to boot during the startup. With this setup, you are allowed to handle different tasks on different operating systems, which can optimize the workflow and enhance productivity.

However, some underlying issues may arise while using a dual boot setup, including:

► The boot menu doesn’t display when powering on the computer.

► An installed system is not listed in the boot menu.
