    Have you tried the repair startup problems option? You mentioned using the select other OS option from the dvd you burned. When 7 was left as default when setting up the dual boot across two drives 7 would load but since 8 was a stand alone install without the 7 host plugged in during the install the 8 dvd repair options took immediate care of the winloader.exe error.

    You have to go through a few other screens first to arrive there however with the new look for the Startup repair tool on the bottom left! First selecting the repair tools option once you arrive at the Install Now screen.

    Click image for larger version

    On the next screen you see the options for other OS not the Startup repair tool or command prompt options which is throwing people off!

    Click image for larger version

    Continue to host, use another OS, Turn off your pc, and no one has identified the Troubleshoot icon as the repair options.

    This one also throws people off seeing the more or less OEM geared option for Refresh your pc or Upgrade to Repair, Reset your pc or full clean install of Windows 8, and the one item to pay attention to which brings you to the screen above is Advaanced options!

    I have actually tried all of those, refreshing, system restore and all the other advanced options. No luck. And I did download the iso off of the official Windows site. It's still downloading, so wish me best of luck!

    I wonder if the issue is related to laptop users
    FYI - I had no trouble to install on a 25GB partition of my Toshiba laptop (it is on a 90GB SSD where space is at a premium). I did have trouble though installing it in Virtual Box on that same laptop whilst the vBox installation on my desktop went like a breeze. So it seems to be erratic.

    I downloaded the 64bit and it simply would not install on VBox or the latest version of VM Player.

    As far as the Automatic Repair that replaces the Startup Repair tool seen with Vista and 7 being an automatic repair tool for finding out what is preventing W8 from loading up. The other options for System Restore wouldn't be expected to help when you first seeing a dual boot set up. That's for rolling back the registry after something goes on wrong once Windows is already up and running.

    When you click on the Advanced options>Automatic Repair that should have fixed and seen the CP start up for you afterwards unless you saw a bad install to begin with. It won't help any if you are able to get 8 on a VM however but install to a physical drive.

    You may want to reformat your E primary just the same if you going for a second download. To save time use a 4gb flash drive over burning a dvd. Besides the MS usb tool a recent freeware found reliable for writing isos to flash drives as well as burning images to disk is called Passcape found at Passcape ISO Burner

    Too bad you weren't working with a second HD however! the OEM boot setup can be a task at times! And 8 despite seeing the same old BCD store and winloader.exe, bootmgr files is still a newer version.

    It will take some time since each time any new build or version in beta/RC is seen people all rush to download! A million downloads in the first 24hrs. went one report!

    It should take close to an hour installing by dvd. likely catch you later if not on the flip side. Have a good install just the same!
