    I have a question about installing an OS to try on a USB hard disk. If I place the ISO on this drive and boot to it, and continue on with the install process, where will it install to? This is important because I do not want to lose all of my Mac files. Thanks in advance!

    Placing the ISO file onto the USB stick will do nothing. You won't be able to boot from a file. Use MRoogle to search for many similar topics (installing OS from USB device).

    Also only one Mac OS X installation can be done per partition, so you need another partition to install another Mac OS X installation.

    If you don't want a clean installation, you can clone your internal HDD to the external HDD via CarbonCopyCloner and SuperDuper.

    You cannot boot to an ISO.

    If I am following you correctly, you want to install an OS onto a USB Drive.

    If that is the case you will need to restore the ISO to some medium. Whether it be an external hard drive, a CD, or DVD.

    You would then boot to that medium.

    The installer for this OS should give you options. Since I don't know the OS you are wanting to try, I can't comment much further.

    That is correct.

    I have extracted the contents of the ISO and placed them in the uppermost directory on this hard drive.

    I am presuming that the drive is now bootable.

    I am trying to install Windows 7. Would this installer allow me to place the new installation onto this drive?
    Thank you!

    You presume incorrectly. You just have a USB stick with Windows install files. If you have a Windows PC to create the Boot USB from you can use this tool from microsoft and your ISO.
