    I have a big problem with dual-boot. I have three partitions:

    C: 146 GB capacity, 73 GB free
    D: 146 GB capacity, 97 GB free
    E: 172 GB capacity, 126 GB free

    So, on C: drive I have Windows 7 Ultimate 32-bit already installed, but yesterday I tried to set dual-boot so I can run both Windows 7 Ultimate and Windows 8.1 Pro. But, I installed Windows 8.1 Pro on D: drive (DVD which I burned with Windows 7 USB/DVD Download Tool using ISO en_windows_8_1_x86_dvd_2707392.iso) without problems and I activated it. But now I cannot manage Windows 7 to work, so instead of this, Windows 8.1 Pro is now default OS, instead of choosing OS on Startup.

    And now, D: drive is now C: drive, and C: drive (Windows 7 drive) is now E: drive. In Disk Management, C: drive is marked as boot drive, but E: drive isn't. If I mark E: drive as active, I cannot run any Windows.

    So, how to set dual-boot so I can choose which system to run?

    My specs of laptop:

    Intel Pentium P6200 2.13 GHz
    Intel HD Graphics Pentium P6200
    3 GB RAM DDR3
    500 GB HDD
    Windows 7 Ultimate x86 and Windows 8.1 Pro x86

    Thank you in advance. ;)

    Now I want to remove Windows 8.1 from dual-boot, but how to do it without formatting partition? In EasyBCD it says that default drive is D instead of C, but default OS is Windows 7. :confused:

    Windows 7 is installed on C, Windows 8.1 on D drive. I'm afraid not to delete Windows 7 from laptop. :eek:

    Yes, but in EasyBCD it says that D drive is default drive (Windows 8.1 is installed on D drive), but default OS is Windows 7 which is on C drive.

    Just do as neofita says. No mater where you install Win7 or Win8 if it is not in the C drive Win7 and Win8 will still say that it is C drive. You could install them in M drive and it will come up as C drive.

    Your only removing the entry of Win8 from the boot screen!!

    If after you remove the entry from EasyBCD and Win7 does not boot up then just pop in your Win7 disk and repair the boot files.

    I switched boot drive from D to C. Windows started normally, but I needed to activate Windows 7 again.

    Now I want to delete Windows 8.1 from my laptop. I am only running Windows 7 Ultimate. I deactivated Windows 8.1 from Boot Menu.

    How to delete Windows 8.1 safely without formatting hard drive?

    Use any partitioning program and just format the drive that Win8 is on as long as it is not on your C drive.

    It's not possible to just delete folders (Program Files, Users, Windows) ?

    I deleted Windows 8.1 in EasyBCD and it haven't anything about Windows 8.1. Only Windows 7 is plugged in boot.

    Yea I guess you could just delete manually the files and folders etc. but there will be things left behind. If you really want to clean it out completely then you have to format it.

    Deleting it from EasyBCD only eliminates Win8 from the boot process. Win8 is still there!
