Win8 – Disable Windows 8 Secure Boot On Dell Laptop Computer

If your new Laptop computer comes with Windows 8 as the built-in operation system, it might has the “Secure Boot” enabled by default. And with “Secure Boot” on, you cannot boot from CD-ROM drive or USB storages, NIC etc.

If you need to boot from CD-ROM drive or USB thumb drive to reinstall the system to Win7 or Windows XP, you need to disable “Secure Boot” on a Dell Latitude E6530, E6230computer, the procedure will be similar to other model of DELL computers, since they use the similar BIOS menu interface.

By default a new Dell windows 8 computer’s boot menu looks like this. (Boot mode is set to: UEFI; Secure Boot: On)
