How to Access Asus Boot Menu

What Is Boot Menu

Boot menu is related to computer boot process. Many people may think that boot menu is the same as the boot order/sequence. The two items are similar but they also have differences. What is boot order/sequence? To explain this item, you should know what the booting process is.

The traditional boot process is as follows:

• Once the computer is switched on, start POST (Power On Self Test) process.
• The BIOS initializes the necessary system hardware for booting (disk, keyboard controllers etc.).
• According to the boot order, BIOS checks the devices (hard disks, removable devices, CD-ROM, etc.) one by one until it finds a bootable drive.
• Once it finds a bootable device, it tries to load bootloader and then the bootloader will load the system from partition to boot it.

Then, what’s the difference between boot menu and the boot sequence/order/priority? The difference is that boot order is permanent while boot menu is temporary. Once the boot order is fixed, your computer always checks drives in that order and therefore it always boots from the same drive.

If you want to boot from another drive, you should change the boot order to make that drive locate at the first place. But sometimes, changing boot order may be inconvenient, because you should change it again if you want to go back to the previous boot order.

Unlike boot order, if you choose a drive in boot menu, then the computer will boot from that drive just for once. When power down the computer and then switch it on again, the computer will boot in the previous boot order as usual.
