if you have a USB flash drive, make sure that is plugged in before you reboot otherwise it may not show up in the boot manager.

the boot manager should appear showing you all the different options on your system.

Press and hold F12 as the computer starts to boot.

this is where a recovery usb or disc or windows installation disc will actually work. this will give you options to boot from CD ROM, USB, Network etc. System will now reboot using the old school CMOS/BIOS some of us are familiar with. Set this to ENABLED (may already be enabled for some of you).

use arrow keys and navigate to MAIN tab.

Note that the SECURE BOOT option is no longer there! That's normal as secure boot is a feature available only with UEFI.

use arrow keys to navigate to the BOOT tab.keep holding F2 until the UEFI screen (aka BIOS) pops up. Press and hold F2, then power on laptop.To do this on my Acer: (firstly, laptop has to be powered off). Disabling UEFI and switching it to Legacy (which also disables secure boot) will allow me to tell the computer to look at other locations when booting up.it doesn't care if I have a windows repair CD, or USB recovery flash drive plugged in. With UEFI (and secure boot) enabled, my computer is ONLY looking for the operating system on the internal HDD (or SSD). my Acer has the “no bootable device” error when booting up.if you hear clicking, then your HDD is more than likely toast. and these make a noticeable sound when they are running (smooth high pitched whirling). More often than not, these are standard with many factory systems. Almost like a high-tech record player there's a spinning platter that stores the data (the vinyl), and a read/write arm with a magnetic head that access the platter (not unlike the tonearm and cartridge-needle on a record player). these are traditional hard drives with mechanical moving parts. they are fast! they tend to be included with higher end systems or as aftermarket upgrades.

Think of it like how a usb flash drive works. Even if they fail, there will never be any clicking sounds, vibrations. there are no mechanical movements in these hard drives. here are some important points that need clarifying. Some misleading and incomplete info in a few of these replies.
