    Sorry, but I ran out of ideas. It is hard to say from here. I have made those installations following the described procedure many times and they always worked. You must have made a mistake somewhere along the line.

    Yup it is marked as "Active, Primary"
    The only other thing I can think of is that there is a problem with the bootmgr. Run this command again from a Windows 8 system: bcdboot F:\windows /s F: /f ALL
    There's another method used for making flash drives bootable to try out. The commands are entered in a command prompt as well. This uses the bootsect.exe tool First you already have the external HD partitioned and formatted but not made bootable as the main cause even when using that line there.

    Instead try the following once yiou have a command prompt open. If your optical drive is D you would first change to that drive at that prompt with "D: cd boot" which changes directory from the "C:\Windows\System32\" default.

    Next you simply type in "bootsect.exe /nt60 G:"(G or drive letter used for exteral HD) command to see the boot information written and boot files unpacked as long as you burned the 8 iso to disk and have that present in your optical drive. If the bootsect tool works the same for 8 as it did with 7 you should see results.

    The installation method for USB HDD using Partition Wizard was causing my problems. Once I went the manual command prompt way, or even using EASUS as a partition manager it worked. Thanks for the help, it might be worth considering removing the partition manager link, and just letting people do it via the tried and tested command prompt?

    Risco,

    This method worked for me also.

    Keep in mind that the bcdboot part can pose problems. It failed for me too when I ran it in Win 7, so I retried in Win8 (in Virtualbox with my usb stick mounted).

    Bcdboot failed also in Dev Preview but worked the second time in CP (hmmmm...)

    This worked for me:
    If you put, let's say, a Release Preview on a usb run bcdboot F:\windows /s F: /f ALL from the same version (Release Preview)
    The next step is obvious, but just in case: if the os on usb is x86, bcdboot has to be x86 also.
    The same rule applies for x64 versions. I'm not sure it's an official rule, but to keep things safe, it should work.

    Regards
    Hopachi

    That is an interesting observation. I did use Partition Wizard myself without any problems but I hear what you say. I know that it is easy to make a mistake with Partition Wizard. I have been victim of that myself in other contexts. I will make a note of the problem.

    When going to prep the 32bit flash drive used here I never used any 3rd party program or even clean with DiskPart but simply right clicked on the flash drive in Windows Explorer to choose the format option. The bcdboot F:\\windows /s F: /f all command worked without a problem. That includes not having used VirtualCloneDrive.

    The other string command I pointed at there is how to see a flash drive or in your case an external usb HD made bootable from the command. You would need to have the RP iso burned to dvd and in the drive however since an installation disk with the files is requireed in order to utilize the bootsect.exe tool.

    It's the same way I did it.
    And if performed correctly, it should work anytime.

    The other method referred to there was how to create a bootable flash drive for installing Vista or 7 but would use the other command simply to make the external HD bootable. The command used accesses the boot folder on the installation media in order to write the boot information on a usb flash drive and could work for the external hard drive as well.

    Did that drive come incased in a sealed factory enclosure or did you place a drive in an external usb closure bought separately? Risco That shouldn't make any difference in general but could be an explaination for why the command didn't work right away for you.

    Just revising this thread with a little more information.

    For those that are put off by a long download to obtain imagex.exe, it is possible to apply the Windows install.wim image using dism.exe - which is found in your c:\Windows\system32 folder.

    dism /apply-image /imagefile:d:\sources\install.wim /index:1 /applydir:t:\

    this is absolutely equivalent to:

    imagex /apply d:\sources\install.wim 1 t:

    and takes a similar time to apply the image. ~20 min

    I have a small tip - if you have difficulty booting from a particular USB device, because Windows wont let you, sometimes putting the installation on the USB Device in a .VHD virtual disk and using that to boot from circumvents some of Windows' prohibition of booting from some removable devices. The VHD file can also be copied as an entity from one device to another, which is good for backups and reinstallation.

    Is my understanding correct, that Windows To Go is ONLY going to be available in the Enterprise version of Windows 8 when released? Thus, the consumer market won't have any access to any of this stuff?
