    How to resize Surface 3 Pro drive by third party utility


    I could manage to resize the system partition by using a third party utility software but think there must be more efficient way to do it. Here's how I did it:
    1. I let the Surface 3 Pro boot from a USB bootable drive for the third party utility.
    2. Noted that I could not resize the OS drive or any drive.
    3. I disabled TPM and Secure Boot Control on UEFI.
    4. Surface 3 Pro did not boot and instead got to recovery mode asking for recovery info.
    5. I could not find the info anywhere and I reset the Surface 3 Pro.
    6. I launched the third party utility again and could resize the partition this time.

    BTW: After the step 6 I enabled TPM and Boot Control, and now I can no longer resize the partition.

    Any suggestions?

    TPM = Trusted Platform Module
    SecureBoot = Prevents anything from loading before the OS

    Both have to be disabled - before trying to boot from 3rd party software.. So it is working as it is suppose to be..

    Your system most likely has 5 partitions ( standard setup for OEM PC's) or has 4 partitions if it has a 32GB drive or less (usually a wimboot setup)

    So what is it you looking for suggestions for ?

    If both are disabled my experience as stated in my previous post indicates I have to go through the step 4 to 6. I would think this cannot be the solution. Or the recovery mode is not supposed to happen?

    There are some Linux distro's that will work with UEFI on, You just boot up on the USB stick that holds the Live version of Linux, then resize with Gparted.

    I am not familiar with Linux. Could anyone point me to a specific Linux distro?

    This is an excellent program, worth grabbing while it is free. Will make it's own bootable PE media as well.

    broe23,
    Do you mean encrypted drive can be accessible from Linux so that I can resize/create/delete its partition?

    KYHI,
    Thanks for the info but this is not a Linux distro or is it?

    If the partition or drive is encrypted, You need to turn it off, before the resizing.

    Trusted Platform Module (TPM) is an international standard for a secure cryptoprocessor, which is a dedicated microprocessor designed to secure hardware by integrating cryptographic keys into devices.

    thus
    If the partition or drive is encrypted, You need to turn it off, before the resizing.

    Thanks everyone for your help.

    I have found out by now that my problem was that I did not know the Surface 3 Pro's hard drive was encrypted out of the box.(W8.1 automatically encrypts if the hardware supports) The encryption key did not come in the box, thus I could not enter the key when requested. BitLocker key I knew is that it is created when a storage device is encrypted. In my problem case, it came encrypted but the system is set up to allow the key to be backed up by the user. I was supposed to back up the key or turn off the encryption soon after the initial basic configuration was done.

    Any comment or correct me if any part of the above is incorrect.
