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.

How To Boot From a USB Device
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.
Tip: The BIOS on most computers list the USB boot option as USB or Removable Devices but some confusingly list it as a Hard Drive option, so be sure to dig around if you're having trouble finding the right one to choose.
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.
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.

• Restart your computer.
• 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.

• Your computer should now boot from the flash drive or USB based external hard drive.

Most PCs will not boot usb, unless the CMOS setup configure supports that device as a boot choice on cold start. F10 or does allow whatever key strokes needed before windows logo, will get you into CMOS config. Then look for boot, sequence and see if the usb is an option, if not, no hope for usb boot.

If CMOS config does allow usb boot AND your usb device has been set up to be a boot device,(and you saved the cmos changes) with the proper files...
shut dow, put in usb and cold start.... save

Go into the BIOS settings then to the device Boot Order.
If USB device is listed in the boot order then you can move the USB as the first boot device.
If the USB device is not listed then your ASUS noteboot cannot boot up with an USB device.

Go to the BIOS settings and then Boot (start up) order and make the USB device the first boot device and the hard disk the second boot device.
If the USB is not listed then your laptop cannot boot up from an USB memory stick.
To make a Hirens USB boot memory stick copy the Hirens files onto the USB memory stick. Then you can boot up Hirens with the USB memory stick.

Boot hp pavillon zd8000 with usb is possible.simply plug the USB flash drive with iso and reboot, then press F10 navigeyt Boot Order Mark hard drive, hit enter, Highlight your usb and press F6 so usb was on top of the press F10

Go into the BIOS setting - Boor/startup order and move the USB to the first boot device.
If your Boot/startup does not have the USB listed then you cannot boot up with an USB device.

If you go into the BIOS configuration then the Device boot order and you do not see the USB port in the list, then an USB boot up option is not available.
If it is available the move the USB as the first boot device so you can boot up with an USB memory stick.

Hi

Thank you for your query

Please try the following

1) Switch on PC
2) Press F12, del or the ESC key to enter setup
3) Go to advanced options and then choose boot options
4) In boot options choose USB peripheral to be set as first boot device
5) Save and exit from the BIOS screen

As the PC restarts make sure the USB flash drive is plugged into the PC

I hope this has been useful

Yes, it is possible to boot to a USB device, even when there is no support in the system BIOS for such a feature. To do this you would need to install a freware utilty, a boot manager, called the PLoP Boot Manager. The PLoP Boot Manager is a small program to boot different operating systems. You can boot the operating systems from harddisk, floppy, CD/DVD or from USB. You can start the boot manager from floppy, CD, network and there are many more ways to start the boot manager. You can install the boot manager on your harddisk. There is no extra partition required for the boot manager.
