Ze5170 not showing usb flash as boot option

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.

did you check in the BIOS settings. Sometimes you have to enable that first to make it visible

Enter BIos ( F1)
Go to startup sequence
locate the excluded device
Press X and set the device in the desire boot order #
Press F10 to save.

No it is not possible unless a BIOS firmware upgrade provides this capability.

Some BIOS will only give you the option for USB if there is a USB detected upon boot. List all your boot options it could also be listed as something like Legacy USB, USB FDD, USB HDD

Ignore it, it just means it could run faster if you had USB 2.0 but almost all USB devices are backward compatible to standard (USB 1)

We are going to do this the easy way....you need a computer of course and one that has a working cd/dvd player, a flash drive and a windows installation disc. A recovery disc will not work...you need a windows installation disc.

Go to the control panel > folder options > click on the "View" tab, scroll down and UN-check the box the says "hide protected operating system files", now click the bubble above that says "Show hidden files and folders.
Now get out of the control panel and insert the windows disc in the drive.

Go ahead and insert the flash drive into a usb port and let windows recognize the device and load it. It will give the device a drive letter.

After the disc loads, it may appear on your desktop and say to install Windows....just exit the program but don't eject the disc. Open "My Computer" and look for your cd/dvd drive and right click on it. Choose "open" from the choices and a list of files and folders will appear. Select all the files except for a file that says "desktop

Copy all the files and paste them into the flash drive that you can find in "My Computer" The files from the disc will now be written to the flash drive. Once the copy is completed, the flash drive can now be used to boot the computer.

Insert the usb drive into the laptop that needs fixing and power it up. After the flash screen appears, tap the F12 key to bring up the multi-boot options. Choose USB drive and hit enter. The laptop will boot off the usb drive and initiate the Windows files.

Have had loads of usb media, as far as I know some USB sticks are bootable others are not, usually it will say either on the manual or on the box of the product whether its bootable. If it is bootable format the usb drive fully then copy the BOOT.INI, NTLDR, and NTDETECT from the root directory of your PC's boot drive to the flash drive. These files are hidden by default, so you will either have to configure Windows Explorer to show hidden files (including protected operating system files) or you will have to open a Command Prompt window and use the COPY command to copy the files. If you choose to use the Windows Explorer method, then open Internet Explorer and enter C: into the address bar so that you are looking at your local hard drive. Next, select the Folder Options command from the Tools menu. When the Folder Options properties sheet opens, select the View tab. Now, just select the Show Hidden Files and Folders and deselect the Hide Extensions for Known File Types and the Hide Protected Operating System Files check boxes. Click OK to continue.

Now that you have formatted your USB flash drive and installed the boot files onto it, the next thing that you must do is to configure your PC to allow you to boot from the flash drive. This is all done through the computer's BIOS Setup. I can't give you specific instructions for this part, because every computer is different. I can give you a few pointers though.
You can access your computer's BIOS by pressing a specific key immediately after you turn the PC on. The key varies, but it is usually either [F1], [F2], or [Delete]. Once you are in the BIOS Setup, you should verify that all of your computer's USB options are enabled. This might include things like support for legacy USB devices or support for USB 2.0. If there is a time out setting for USB devices, you should set it to the max to insure that the system doesn't time out while waiting on the USB device to boot.
Next, find the section on boot device priority. Normally, a USB flash drive (which is usually listed as USB-HDD, but may be listed as a removable device) will have a very low boot priority. If the USB flash drive's boot priority is lower than the hard disk (listed as HDD) then the only time the computer would ever boot off of the USB flash drive is if the system were to fail to boot from the hard disk. You must therefore rearrange the boot device priority so that the flash drive has a higher priority than the hard drive.
