There are times when you’d need to run another operating system to get things done on the same PC. Dual boot lets you select which operating system loads when you start your computer. Sadly, our readers report that the dual boot menu not showing on their PC.

Why is the dual boot menu not showing?

The dual boot menu not showing while booting up can occur for many reasons. Some notable causes of the problem are:

  • Fast startup is enabled – The fast startup option allows the system to boot directly into the default operating system. So, not disabling the fast startup option during dual boot may cause the issue.
  • The dual boot option is disabled – Because not all systems have two operating systems installed, the option isn’t enabled automatically. Hence, you may not see it.
  • Corrupt system files Corrupt system files on your PC can cause the boot manager to malfunction, resulting in the dual boot option not showing during startup.

Whatever the cause, we’ll discuss getting the dual boot menu to appear again on your PC.
