    Windows 10 Installation Problems On Seperate Internal Harddrive


    Has anyone heard of any problems with installing 10 on a separate hard drive with another os system like 7 ? I want to get rid of my 8.1 installation and go with 10 but I did have a few problems with the 7 install even though it was disconnected from my board during the install of 8.1 but that was only until I shut down and reconnected the drive and started back up booting into 8.1. I can't for the life of me remember what all took place but it was a close call from having to rebuild the whole operating system 7 that is. I didn't reconnect the 7 drive until 8.1 was all finished with updates and what ever else Software, ETC I installed .

    Assuming you are going to install Windows 10 on a separate HDD than your current Windows, there are two ways to proceed.

    1. Leave the old OS HDD installed when installing Windows 10. Doing it this way should set up dual booting automatically, but the issue is that Windows 10 will not create a new set of boot files. It will modify the existing boot files. Those are likely to be and remain on the old OS HDD. So, if you ever want to remove or reformat the old HDD you are going to have to move the boot files.

    2. Disconnect the old OS HDD before installing Windows 10. This will cause Windows 10 to set up boot files on the same HDD Windows 10 is installing to and it will not set up dual booting. You can then dual boot in two different ways. Just reconnect the old HDD and go into bios each time you want to change boot order. That is very cumbersome. Or reconnect the old HDD and add the old OS to the Windows 10 boot menu to set up real dual booting. There is a single command line that you can run to do that, I'll have to look it up.

    The command line would be:
    bcdboot e:\windows /d /addlast

    where the path in red would be the path to the old Windows you wanted to add.

    since booting to the UEFI is no problem at all with this board , F8 choose and I'm done . I'm just am looking for some problems that someone may have run into during their install this way.

    Not 100% certain, but can you run just msconfig and select default OS?

    I know you can do this for dual boot pcs, and you can do it booting from a macrium rescue drive.

    Might be worth a try as would be faster than swapping in bios.
