Entering UEFI from a Windows 8 system
I wanted to boot a Dell Inspiron 14 5000 series laptop (model number 14-5447)
from a USB flash drive to perform an image backup of the internal hard disk
drive (HDD). I had placed the Clonezilla backup program on a USB flash drive -
see Creating a Clonezilla
bootable flash drive - and wished to use it to create an image backup
of the system's hard disk drive before upgrading the system from Windows 8.1
to Windows 10. But, in order to boot from the USB flash drive, I needed to
change the Universal Extensible
Firmware Interface (UEFI) settings to allow me to boot the system from the
external USB flash drive. The steps to modify the system settings are listed
at Entering UEFI from a Windows 8
system. Though these steps were written for this specific system, a similar
process can be followed on other systems.
