Overview of UEFI BIOS Boot Options

Compared with the traditional BIOS boot, EFI/UEFI boot is a more advanced and flexible booting mechanism. UEFI (Unified Extensible Firmware Interface) refers to a modern firmware interface that is commonly used in newer computers and operating systems. UEFI replaces the older BIOS (Basic Input/Output System) firmware interface.

Your system drive might be a GPT drive and the system is with EFI/UEFI boot. As known to all, it is quite complicated and time-consuming to boot into BIOS/UEFI to change the Boot Options. For different brands of computers, the key to enter into BIOS might be different. Normally, you need to constantly press a specific key (usually DEL, ESC, F1, F2, F8, F9, F10, F11, F12) to enter into BIOS/UEFI and change the Boot Options. And, you need to specify and change the Boot Sequence manually. The whole process might be difficult for one without computer experience and it will take time to finish the operation.

Now, with the UEFI BIOS Boot Options Manager in AOMEI Partition Assistant, you can easily and quickly change the boot sequence, delete, backup, restore, and refresh your EFI/UEFI BIOS Boot Options without manual entry into BIOS and complicated modification of startup entries. It will significantly save your time to quickly manage the boot options.
