    Need to move Windows boot manager from Win 7 drive to Win 10 drive


    I have found that when I installed Win 10 Pro 64 on my PC, on a new SSD drive, it put the boot manager on the old Win 7 drive. Perhaps that was because it was in the Drive 0 Sata port and the new SSD was in port 1. Didn't know that at the time. I've used the " which OS do you want the launch " blue screen all this time. Win 10 being the default. If I unplug the old drive, my PC finds nothing to boot to.

    I looked at the drive partition info in the "Computer Management -> Disk Management" part of Win 10 and see my C drive is not set as active, but a small System Reserved partition at the front of the Win 7 partition is. The Win 10 partition is set as " Boot, page file, crash dump, Primary partition " and Healthy. With a secondary partition as Recovery Partition.

    I used diskpart to verify I am not using an EFI type partition. Doesn't say EFI on any partition in the Manager screen either.

    I looked in the c:\boot\ folder on the Win 10 partition and it was empty. I couldn't find where it is supposed to be hiding on Win 7 partition. The Reserved partition is empty as well, but it is listed a " System, Active " I assigned a drive letter to it long enough to browse it.

    Where is the boot manager and how do I move it ?

    :)

  2. Dual-boot Win10/7 or go back to Win 7

    Separate Hard Drive for win 7 and win 10
    select boot drive at bios when Booting ( F10 )
    Keeps them entirely separate and makes wipeing disk later easier

    Win 10 boots...

    Yes, it's called the Windows Technical Preview and you can get it here (ISO Download)

    You'll have to sign up for a MS account using your email and a password.

    I'm using it with a 480GB SSD as the OS drive and it ~does~ boot faster, much faster.
    I also have a new Win-7 build with a pair of 120GB SSDs in RAID that takes longer to boot.

    Need to move Windows boot manager from Win 7 drive to Win 10 drive

    Win 10 boots...

    Anyone else notice Win 10 boots much faster into Windows? I mean much, much faster.
    I am now getting into Windows almost as fast as my SSD drive on my other machine.
    It's crazy fast for me.
