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.

Free usb reboot


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.

When a PC boots it searches for system files such as command.com,io.sys,msdos.sys. So, if you do not have the bootable files in your usb drive your PC will never boot from usb drive.

My pavilion dv5000 says on startup media test failure check cable


Computers can start-up ("boot") from many different devices:
* 3.5" diskette,
* CD-ROM,
* USB memory-stick,
* disk-drive,
* network,
* external USB CD-ROM

and so on.

Your computer is trying to use the network adapter to download a bootable image through a connection with a network-cable to a "network-boot-server" computer.

In your case, "check cable" means that your computer's network-port is either *NOT* connected to a network, or that no "network-boot-server" responded to the request to download to your computer.

First, check the "boot-order", i.e., the priority of each of the bootable devices, to ensure that "boot from network" has a LOWER priority than booting from your diskette, your CD-ROM, and your disk-drive.

Second, check that your disk-drive *IS* one of the bootable devices.

Is there any bootable media in the diskette?
Is there any bootable disk in the CD-ROM?

If not, then your computer has *TRIED* and *FAILED* to boot from your disk-drive, and then tried and failed to boot from the network.

So, it's possible that your disk-drive has failed.

Take the computer to a qualified technician, and get them to remove the disk-drive from your computer, and to connect it to another computer, to see if the disk-drive still is in working-order.
