Points of My Scenario
1. I received a custom ISO for creating a bootable CD.
2. The bootable CD is used to boot a machine and instruct it to download an OS image from a remote server.
3. The machine to be configured does not have an optical drive (No DVD/DROM drive).
4. I need to create a bootable USB flash drive from the ISO.
QUESTION: What trustworthy utility/process can I use to create the bootable flash drive from the bootable ISO?

    If the iso is linux based, you might be able to use unetbootin to create a bootable USB stick from it. This works for many, but not all distro's, though:

    Accepted Solution

    A couple great utilities to accomplish this are.

    WinToFlash starts a wizard that will help pull over the contents of a windows installation CD or DVD and prep the USB drive to become a bootable replacement for the optical drive. It can also do this with your LiveCD.

    -UNetbootin, Universal Netboot Installer
    UNetbootin loads utilities or installs Linux/BSD to a partition or USB drive without a CD. It can use an existing disk image/kernel/initrd file, or download a supported distro or system utility (such as Ubuntu, Fedora, openSUSE, FreeBSD, PartedMagic)

    I find this program very helpfull in making different types of installation "cd`s" on a usb disk Works fine with all iso, img files that I have tried (a lot)

    Mount your bootable ISO to an image drive. For this example I will use drive D: as the image drive, and drive E: as the flash drive. This is the command you use to create an exact copy of a disk on to another volume.

    xcopy D:\*.* E: /s/e/f

    This can be used for instance, to copy the Windows DVD to an appropriately sized USB flash drive to install the OS from there. I have tested this at work a few times and it installs in about the same amount of time, but without the worry of caring for the DVD (scratches) or having problems with the lens in the DVD drive reading the data.

    You don't need /s if you have /e. Those are mutually exclusive. /f just shows you the files.

    However, if any file has the hidden or system attribute set, you'll need /h as well.

    xcopy does not copy boot sectors. At least not by default

    Wintoflash was the utility that was applicable for my custom boot CD. It was a customized WinPE-based ISO that is based on the Windows Server 2008 OS. I had to choose the "Transfer WinPE Vista/2008/7/8" option. Worked like a charm!
