    Hello Golden,

    It modified the MBR on my PCI-E SSD when I installed Windows 8 to a separate HDD, so it should do the same for you. I would recommend to leave the SSD plugged in so that it will be included in the dual boot setup, and unplug any other HDD that you are not installing to to help prevent it from getting the MBR placed on it by mistake.

    When you are finished installing Windows 8, you should see the Windows Boot Manager from Windows 8 afterwards at boot.

    Please let us know how it went.

    Hi Brink,

    Thanks. Unfortunately it didn't work....in fact I was left with having to do a Repair Install and MBR fix on my Windows 7 installation

    These are the steps I followed:

    1. Unplugged all Samsung HDD's with the exception of the WD HDD to which I wanted to install W8 - I also left the OCZ SSD plugged in.
    2. Booted from the Windows 8 ISO.
    3. Select the WD HDD to install Windows 8 (if was formatted as a single primary partition)
    4. Clicked Next
    5. Was presented with a message that i could not install to this disk.
    6. Deleted the partition, reformatted it as Primary, and tried again - same message
    7. Exited installation and shutdown PC
    8. Removed USB and tried to boot into Windows 7

    I was left with :

    Loading Operating System ...
    _

    Attempted a few unsucccesful Repair Installs on the Windows 7 installation, but I think the MBR was damaged? Booted into PW7 ISO and repaired the MBR, and have my W7 back again.

    So.....did I miss something critical here? I'm absolutel positive I tried to install to the WD (its the only WD HDD I have).

    Golden

    Golden,

    The drive letters at boot will not always be the same as they were from within Windows, so I suppose that you could have used the wrong drive letter to install to.

    Hi Brink,

    I'm confused, there were only two options to install too : the SSD (C drive) and the HDD (H drive), and I selected the HDD. How do the drive letters come into play here?

    Thanks,
    Golden

    Sorry, I had thought you did it at boot.

    Hi Brink,

    No worries. It seems for whatever reason the dual-boot setup is just not working for me....not entirely sure why. I'll do some research and see if I can work out where the problem lies....

    Thanks,
    Golden

    The way you tried it should have worked. Apparently there is something in your WD HDD that the installer did not like.

    Unplug all other disks including the SSD and leave only the WD. Then lets see what happens. If the installer is still coughing, we'll have to see what's wrong with the WD.

    Hi Wolfgang - it works perfectly if the SSD is not plugged into the motherboard.

    Regards,

Replace Vista with 8 on dual boot PC
I have a Vista and Win 7 dual boot desktop. I want to replace Vista with 8. Is it just a case of booting into Vista and running the 8 install DVD as I did when I upgraded to 8 on my Win 7 laptop? What chance is there of the process screwing up booting into 7 Do you recommend any precautions?
