    Install Windows 10 as dual boot without USB or DVD


    Hi guys,

    I have the Windows 10 Pro ISO with a Windows 10 key. (from MSDN)

    I want to install Windows 10 as dual boot with Windows 8.1. Both are x64.

    Is it possible to install Windows 10 from the ISO? I know you can upgrade that way. But I want to do a clean install AND install alongside Windows 8.1.

    :)

    Install Win 10 Pro as dual boot currently have Win 7 Pro

    Can do Partitioning during install or better do from Win 7 Pro disk manager?

    New self build PC or install Win 10 PRo as dual boot

    I will build a PC myself, i already have SSD so

    Partitioning or erase/format NTFS can be done during install[Win 10 Pro]? I want delete all data in ssd when adapt to new build...

    Installing Win 10 Pro from usb flash drive is better than using an external usb 3 dvd writer & dvd with Win 10 Pro? the latter should boot from dvd... if set boot from usb? better use usb 2 or usb 3?

  3. Windows 10 Upgrade from Win 7

    How did you initiate the upgrade to Windows 10, using the Media Creation Tool or ISO burnt DVD or bootable USB?

    Are you sure a dual boot configuration has not been created?

    Are you able to boot into the Windows 7 installation listed?

    Create a system repair disc just in case.

    Create a new partition on your drive or install to a separate drive, should have no problems.

    I have cleared a partition for Windows 10.
    C:\ = primary = 100GB: has Windows 8.1 on it
    D:\ = primary = to be used for Windows 10
    E:\ = logical/secondary = data partition

    There are other system partitions too.

    So you are saying that I can simply mount the ISO in Windows 8.1 and run the setup and choose D: partition as the install location for Windows 10 and it will work?

    I tried it. Sadly, the installer doesn't give the option to choose the partition. It just uses the same partition where Windows 8.1 is installed.

    I only get 3 options.

    1. Save settings and user data : means, upgrade
    2. Save only user data : means, upgrade
    3. Delete everything : means clean installation deleting windows 8.1

  9. Without researching, the fastest answer I can give you would be the following.

    1) Disconnect your existing HDD.
    2) Connect a new/spare HDD.
    3) Install Windows 10 to the new/spare.
    4) Reconnect previous HDD.
    5) Ghost/Clone the new/spare to your partition on the previous HDD.
    6) Run the Windows boot repair on Windows 8 or 10, they should both add the second entry. (Or manually add the entry using Bootcfg?)

    Too tedious. I'll probably get someone burn a DVD then.

    i downloaded Windows 10 in VHD format. Can it be used to install Windows? For example, copy everything on it to the physical partition, do a boot repair and Windows will make it bootable? After that, it will probably redetect all the hardware?

    Because that guide is from last year so it refers to preview builds.

    Microsoft probably removed the ability to mount a Windows 10 RTM ISO and run the setup from there to install it as dual boot. I have no other explanation why the custom install option isn't showing. This probably is due to activation.

  13. Install Windows 10 as dual boot without USB or DVD

    RTM = Release to Manufacturing. I've always read it as Released to Market meaning it's "good to go" or stable. There are differences between Technical Preview (Alpha/Beta) and RTM. The link I sent him referred to a Tech preview which had the ability to do side-by-side installations. Which would of been the solution to his problem.
