You might want to boot from a USB device,
like an external hard drive or a flash drive, for many different reasons.
When you boot from a USB device, what you're actually
doing is running your computer with the operating system that's installed on the
USB device. When you start your computer normally, you're running with the
operating system installed on your hard drive - Windows, Linux, etc.
Follow
these easy steps to boot from a flash drive, an external hard drive, or some
other bootable USB device.
Time Required: Booting
from a USB device usually takes less than 10 to 20 minutes.
Here's How:
1. Change the BIOS boot order so the USB device option is
listed first. The BIOS is
rarely setup this way by default.
If the
USB boot option is not first in the boot order, your PC will start "normally"
(i.e. boot from your hard drive) without even looking at any boot information
that might be on your USB device.
Note: After
setting your USB device as the first boot device, your computer will check it
for boot information each time your PC starts.
Leaving your computer configured
this way shouldn't cause problems unless you plan on leaving the bootable USB
device attached all the time.
2. Attach the USB device to your computer via any
available USB port.
Note: Creating
a bootable flash drive or configuring an external hard drive as bootable is a
task in itself. Chances are you made it to my instructions here because you
know whatever USB device you have should be bootable after
properly configuring BIOS.
3. Restart your computer.
4. Watch for a Press any key to boot from
external device... message.
On some
bootable devices, you may be prompted with a message to press a key before the
computer will boot to the flash drive or other USB device.
If you do
nothing, your computer will check for boot information on the next boot device
in the list in BIOS (see Step 1) which will probably be your hard drive.
Note: Most
of the time when trying to boot to a USB device there is no key-press prompt.
The USB boot process usually starts immediately.
5. Your computer should now boot from the flash drive or
USB based external hard drive.
Note: What
happens now depends on what the bootable USB device was intended for. If you're
booting to Windows 8 or Windows 7 installation files on a flash
drive, the operating system setup will begin. If you're booting to the DSL version
of Linux, it will start. You get the idea.
