Most of our installs now use an operating system which boots from USB.
Sometimes the computer itself needs to know that it is supposed to boot from USB. To make this adjustment requires some knowledge of how to get into what is called “BIOS”, the most “Basic Input/Output System” for a computer.
BIOS is a hidden setup area that is accessible by hitting a few keystrokes when you first start up your computer. Below are the basic steps:
Step 1: Plug in a USB keyboard.
Step 2: Turn on the computer.
Step 3: Start repeatedly pressing the DEL key.
Step 4: If DEL key doesn’t work, look at whatever quick message is flashing – some computers require you hit a different key, like F1 or F10.
Step 5: You should see a page come up that looks like the image gallery below. Use the up arrow/down arrow keys to move between the different options – and hit ENTER key to choose the option. To get back to the main page, you usually can hit the ESC key.
Step 6: What you are looking for is the the HARD DRIVE BOOT ORDER. You want to make the USB the first option.
Step 7. What you also want to change is the POWER MANAGEMENT feature. It should be set to the “ON” option in case of power failure.
Step 8: Press F10 to save settings and reboot.
Step 9: If you don’t get a message like the last image in the gallery below – you’ve missed something. Keep playing with BIOS. The challenge with the screenshots below is BIOS looks a little bit different depending on the manufacturer – so the onus is on you to click around a bit to find the hard drive boot order and power management features.
