Alternatively referred to as boot options or boot order, the boot sequence defines which devices a computer should check for the operating system’s boot files. It also specifies the order devices are checked. The list can be changed and re-ordered in the computer’s BIOS as shown in the example below.

In the example above, the computer first looks at Removable Devices (e.g., Floppy diskette drive. If nothing is in the drive or it wasn’t bootable, the computer moves on to the Hard drive. If an operating system such as Windows is installed, the computer loads the operating system from the hard drive. If nothing was installed on the hard drive or it was not found, the computer would boot from the ATAPI-CD-ROM. Finally, if the computer could not boot from any of the earlier options, it would attempt to do a Network Boot. The most common devices to be listed in the boot sequence are the disc drive (CD or DVD), hard drive, USB fLASH DRIVE and SSDs

How to change the Boot Order on Windows 10

Open Windows Settings > Update & Security > Recovery Advanced Startup and click on Restart now.

This feature lets you access Advanced Options such as:

  • Boot Windows from a device or disk (such as a USB drive or DVD).
  • Change your PC’s Firmware Settings.
  • Configure Windows Startup Settings.
  • Restore Windows from a System Image.

When you click on Restart Now, it will reboot your PC, and offer you all the above mentioned Advanced Options. Select Troubleshoot > Advanced Options. This section offers further options which include, System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.

Select UEFI Firmware Settings, and it will let you restart your PC. Once the computer boots up, it will take you to the Firmware settings.

  • Switch to Boot Tab.
  • Here you will see Boot Priority which will list connected hard drive, CD/DVD ROM and USB drive if any.
  • You can use the arrow keys or + & – on your keyboard to change the order.
  • Save and Exit.

Now, when you boot it will follow the sequence in which you have set in your BIOS or UEFI Firmware Settings.

This comes in very handy when you want to boot from a DVD drive, which has Windows 10 Installation files or if you have another Windows installed on secondary hard disk.

NOTE:  If you have a Bluetooth keyboard, it will not work here. You will need a hard-wired keyboard to navigate and change the options. Also, Touch features will not work here.
