    Thanks for the info, think I'm getting my head around it now. I have been reading up on the subject, just wasn't clear at the first reading.

    Looks like the 300MB Recovery partition is for OEM Windows RE Tools, if they require them, which would be likely if they add a Recovery Image at the end of the disk.

    Recap:
    If you want the Windows 7 style dual boot page, install W8 first.

    If you want the W8 style dual boot page, install Windows 7 first.

    The second OS installed can be installed to an additional Basic partition, for example after the first OS and at the end of the disk, from a Bootable USB Flash Drive for UEFI.
    Are there any precautions needed before the second OS is installed?

    I was looking that one.

    300MB Recovery partition is for all uEFI installs.

    Just edited my last post before I saw your reply, from 'Recap:', is that the correct way to add the second OS to the same drive (SSD will have both OS installed)?

    If you install Windows 8 first, you can still have the Windows 8 style dual boot page, by doing a Refresh.

    Ok, sounds a bit easier to install Win7 first.

    Have both 7&8 install USB sticks made from the 'How to Create a Bootable USB Flash Drive for UEFI' tutorial.
    With #11 on the Win7 USB stick.

    Thanks for clearing that up for me.

    Hi Dave

    I personally would go for Windows 8 first,
    Ref: SevenForums, all the problems, we have had with System Reserved Pairtition being to small.

    Everything installed with no problems.
    GPT and dual boot 7&8 on my new Samsung 840Pro SSD.
    No 300MB Recovery partition was setup during the installation. It does have the 100MB EFI System Partition and the 128MB Windows reserved partition.

    Installed with all HDDs disconnected, when I connected one of my HDDs (previously with two OS partitions and a data partition) it wouldn't boot, went to Automatic Repair and still wouldn't boot. Removed HDD and it boots.
    Another HDD, for backups, connected and the system boots with no problem.
    Worked fine on old motherboard.
    Still works on other desktop.
    Passed HDD long and short tests.
    Deleted the Win7 OS partition, still won't boot in new system.
    Deleted HDD 100mb System Partition, still no boot.
    Configured a port for Hot Swap, can connect the HDD after boot and everything works.
    Moved the data partition to the backup HDD, previous data HDD is not connected. System is running great.

    Does this have something to do with the GPT set up on the SSD?

    Hi Dave

    1) 300mb partition is only made when Windows 8 is install first.


    2) When Windows 8 is installed, if you add a HDD with a OS install to it, 8 will go into repair mode.


    3) NO, the same with MBR.

    4) When you shutdown Windows 8, Windows 8 will do a hybrid shutdown.

    Base of
    4A) Closes all open windows & Apps.
    4B) Copies all ram info to the HDD.
    4C) Turns off the hardware.
    4D) When restarted Windows 8 will do a hybrid boot, & picks up right from where you shutdown.


    4E) To by-pass hybrid shutdown, you can do a command-line shutdown, shutdown.exe /s /f /t 00.

    No problem with not having the 300MB partition.

    I installed W8 on several systems, all other drives disconnected, never had a problem connecting a HDD with Windows 7 installed. I use the one time boot (F12) when I want to use it.

    My other desktop has a single OS, W8 installed with MBR, and the HDD with a Windows 7 partition works fine when connected on it.
    Same with my previous build, W8 and Windows 7 on a SSD, separate HDD with one Windows 7 partition, no issues when it was connected.

    Never had a problem with hybrid shutdown on any system.
    I understand how it works and don't have any problems with it on the GPT system.

    Must be the partition sector on the HDD, even after I removed the Windows 7 partition and the System Reserved partition the GPT SSD still won't boot when the HDD is connected to the GPT system.

    I'll format the HDD in question, it should be able to be connected to the GPT system then.

    Considering your different set-up seems to isolate both drives from each other. In your opinion does this method you incorporated guarantee no cross-contamination of either drives from such things as virus's?
